Going Back to Basics – My Week With a Canon EF 50mm f/1.8 II Lens


The demise of my first Canon EF 50mm f/1.8 II lens was an unfortunate one.
First, I dropped it – which is OK.
It happens. Still recoverable, I know.
Until, clumsily, I stood on it too.
And, just to be sure it was finished, what was left of the lens then rolled down a small hill. When I caught up, I scooped it up in my hands, all scratches and broken glass. It was my first, and I was gutted.
Nevertheless, after what seemed like an appropriate period of mourning, I did what any photographer would. I bought something newer, and shinier.
I decided to graduate to a Canon EF 24-105mm f/4L IS USM. From there it was all systems go, zooming in and out of those hard to reach spots and enjoying the freedom that a versatile medium-range workhorse affords. And despite the occasional bashing here and there, its been my go-to lens ever since.
Recently, however, I acquired another Canon EF 50mm f/1.8 II. Just like my old one, but much less crunched. So I decided to see what going back to a prime lens would be like. Especially after relying so heavily on the reach of the Canon EF 24-105mm f/4L IS USM. Here’s a quick rundown on my week with the Canon EF 50mm f/1.8 II and why a break from your old favorite can be surprisingly beneficial.
Ditching the weight of the Canon EF 24-105mm f/4L IS USM had another benefit too. Without swinging around a heavy lens, I was able to move a lot more freely. I could crouch, jump up and down, do some parkour…
Okay, I’m not that athletic.
However, being able to move allowed me to line up shots with more ease.
A lighter lens meant I could easily sneak my camera under this umbrella for a photograph

Slowing it down

The technical differences between Canon EF 24-105mm f/4L IS USM, and the Canon EF 50mm f/1.8 II took some getting used to – zoom being one of the most pronounced. Instead of getting closer to a subject in-camera, I needed to reassess what I wanted to achieve. This meant strategically positioning my body to get the shot. Sure, I walk around seeking out subjects to photograph all the time. But, with the Canon EF 50mm f/1.8 II, I needed to be just a little more active to get the image I was after.
Sticking with the Canon EF 50mm f/1.8 II got me thinking about the physical and mental elements that come together to create a successful shot. It made me slow down and appreciate the machinations of photography and the tactility of the image-making process.

Lots of light

One of the biggest differences between the Canon EF 24-105mm f/4L IS USM and the Canon EF 50mm f/1.8 II is written in the name of the lenses themselves. It’s aperture. While the Canon EF 24-105mm f/4L IS USM can manage a valiant F/4, it doesn’t quite cut the mustard compared to the Canon EF 50mm f/1.8 II, opening up to an aperture of f/1.8.
What does this all mean? Basically, the Canon EF 50mm f/1.8 II can allow a lot more light to pass through to the camera’s sensor. That’s a big deal in low lighting conditions. For example, shooting at night with the Canon EF 24-105mm f/4L IS USM may require a much slower shutter speed or higher ISO value to achieve the same exposure the Canon EF 50mm f/1.8 II can at a faster shutter speed and a lower ISO. This means that the Canon EF 50mm f/1.8 II can produce much better image quality in low light.
Photographing in darker environments can be challenging. But the Canon EF 50mm f/1.8 II allowed me to experiment at different times of the day without having to worry about available light. Of course, its a consideration when calculating exposure, but I was a lot less concerned about clogging up my images with insane amounts of noise than I would be with the Canon EF 24-105mm f/4L IS USM in the same conditions.
The f/1.8 aperture of the Canon EF 50mm f/1.8 II allowed me to take this shot with a lot less noise and a faster shutter speed

Extension tubes

Another benefit of the ample aperture of the Canon EF 50mm f/1.8 II is its versatility when coupled with a set of extension tubes. Extension tubes physically move your lens away from the focal plane. This makes the minimum focusing distance (the shortest distance at which a lens can focus) smaller, meaning you can get closer to your subject while still maintaining focus. It’s a way to shoot macro photography without an expensive dedicated lens.
However, extension tubes do have their drawbacks. One of them being diminishing the available light in a scene. With the addition of each extension tube, less light is able to reach the camera sensor. This drop in light can be difficult to contend with if you don’t have a tripod and a perfectly still subject. A fast lens like the Canon EF 50mm f/1.8 II is ideal in this situation. Even on a terribly overcast day, I was able to get some nice, sharp shots at a decent shutter speed. It meant that I could hand-hold my camera to take macro shots that may have required a tripod with the Canon EF 24-105mm f/4L IS USM.

Bokeh

One aspect of the Canon EF 50mm f/1.8 II lens that I was eager to experiment with was its capacity for bokeh. A Japanese word meaning ‘blur’or ‘blurry’, bokeh refers to the quality of the out of focus parts of an image. The term is often used to describe how unfocused bright points in a scene are rendered as disks of light in a photograph.
While all lenses are capable of bokeh effects, zoom lenses tend to smooth a background over rather than shape it. Prime lenses, on the other hand, deliver a more defined disk-like bokeh result. In addition, bokeh requires the lowest possible aperture value to take full effect. This makes the maximum f/1.8 aperture of the Canon EF 50mm f/1.8 II ideal for some sweet bokeh magic.
Seeking out opportunities for bokeh made me re-evaluate my surroundings. I had to quickly develop an eye for points of light that I could use to disperse into globes of color. But with the ease that a small camera lens affords, the little ‘nifty fifty’ produced some really fascinating results with little effort on my part.
Testing bokeh out on a rainy night in the city

There are plenty of other comparisons to explore between the Canon EF 50mm f/1.8 II and the Canon EF 24-105mm f/4L IS USM. I know, a week isn’t a very long time to truly get accustomed to a new piece of equipment, but challenging myself to a week of prime-lens-only photography was a lot less difficult than I thought it would be.

In fact, it was pretty fun!
Up until now, I’ve been a one-camera-one-lens kinda gal.
But playing around with the Canon EF 50mm f/1.8 II made me think twice about my equipment repertoire. And with the weight and maneuverability of a small mammal, captivating bokeh and such a tight performance in low light conditions, I think I might just add it to the camera bag too. Just in case.
Without stepping on it this time.

Do you use the nifty fifty?


Review: Yongnuo 50mm f/1.8 lens for Canon – At just US$50 could this be the most affordable “nifty fifty”?


The 50mm f/1.8 lens, or as we call it, the ‘Nifty Fifty,’ is one of the most widely used lenses in the market. This is usually the first lens a modern digital camera owner desires to purchase after the kit lenses.
The reasons why this is the most popular lens are fairly simple – the first being affordability, and the second, the ability to produce pleasing bokeh.
In terms of affordability, the Yongnuo 50mm f/1.8 lens is ideally the cheapest Nifty Fifty. Priced at less than US$50, this is less than half of the Canon variant and works on APS-C as well as full-frame cameras.
However, the Yongnuo lens for Nikon costs around US$70 as it includes the focus motor. I recently bought one for my Canon 5D Mark iii, so I thought of sharing my views about this lens.  

Build quality and ergonomics

The Yongnuo 50mm f/1.8 lens looks exactly like the Canon 50mm f/1.8 lens(discontinued version). The plastic used in the Yongnuo lens feels a bit cheaper though. Surprisingly, the rubber grip is smooth, and the ‘AF and MF’ switch is similar to Canon.
The construction of the lens consists of 6 elements in 5 groups and has 7 diaphragm blades – the same as the Canon variant. This Yongnuo lens is light to carry as it weighs only 120g – 40g lighter than its competitor. Overall the lens looks and feels good at this price point.

Focus speed and accuracy

I have been using this for almost a month now, during the day as well as night time. The focus speed is a bit slow as the lens hunts for focus, especially in low lightconditions. If you are shooting stationary subjects, then it is fine, but if you want to nail the focus swiftly, then you might be disappointed.
Though the focus speed is not that fast, the accuracy is fairly good. It takes time to focus but when it does the focus is accurate. I would not recommend this lens for video shooters as it messes a lot with the focus. However, if you are a hobbyist and casually shoot portraits or still objects, this lens can do the job.

Sharpness and Image Quality

Before clicking photos using the Yongnuo 50mm f/1.8, I had much less expectation from this lens. To my surprise, this lens produced amazing sharpness and image quality. I did not compare it side by side with its competitor lens, but I am sure it is on par with it.
The few image samples that you see are all shot at an event during the sunset/evening time. The images are tad sharp, and the colors also look natural. I had done a test on vignetting performance, and at f/4 it was almost gone. This lens worked for me when I was shooting stationary subjects as well as when shooting performing artists at an event.
For me, the bokeh shape was a bit unpleasant at f/1.8, and I’m not sure exactly why. I used this lens at f/2.8 and achieved sharp and crisp images with minimum vignetting and shallow depth of field effect.

This lens by Yongnuo is for someone who has just started with photography or has a tight budget but still wants to achieve the f/1.8 look at 50mm. The focus speed is something that might irritate you, but once it focuses the image quality is quite impressive. I would suggest this lens to someone who shoots still subjects or portraits without much movement. If you are a wedding, event or a professional portrait photographer, you might be disappointed.

Review of the Sigma 28mm f1.4 Art DG HSM for Canon


A couple of weeks ago I got my hands on the Sigma 28mm f1.4 Art DG HSM for Canon (also  available for Nikon, and Sony) and got to play with it for a couple of weeks. Let me tell you; it was a tough one to give back. This lens is quite amazing in terms of build, weight, and, most importantly, performance.
Karthika Gupta Photography Sigma 28mm f1.4 review

Ergonomics and build

The Sigma 28mm f1.4 Art DG HSM is a very standard Sigma lens when it comes to the ergonomics. Many of their primes more or less follow the same formula when it comes to the exterior design. In this case, and with pretty much most cases, there is a large rubber ring that makes up the focusing ring. This rubber ring helps greatly when it comes to the grip and overall ergonomic feel of the lens. The front of the lens has a 77mm filter thread and comes with a lens hood. The side of the Sigma 28mm f1.4 Art DG HSM has a switch for autofocus control.
The Sigma 28mm f1.4 Art DG HSM has weather sealing built into the lens. I was able to test this when I took it out in the snow. We have had an unusual cold spell here in Chicago, and when I was walking around downtown with this lens, the temperatures dipped, and it started to snow. I was a bit apprehensive taking out my gear in the snow, but I am glad I did because this lens performed beautifully with my weather resistant Canon 5D MkIII. Photographers who regularly operate in the outdoors with rain and snow will find this beneficial.
When you hold the Sigma 28mm f1.4 Art DG HSM, you feel a solid lens. My primary everyday lens is a Canon 24-70mm f/2.8. This lens has been in my bag for the past 9 years, and I like the feel of the solid form and am comfortable with the weight. The Sigma 28mm is a bit smaller, and a little lighter than I am used to, so switching to it was a non-issue for me.

Technical Specifications (from Sigma)

These specifications are from Sigma’s website.
Typical photography applications for this lens is listed as Creative, Travel, Landscape, Wedding & Events, Family. 
  • Best-in-class performance
  • Dust- and splash-proof structure
  • Designed to minimize flare and ghosting
  • Designed to meet all shooting conditions
  • Compatible with Canon Lens Aberration Correction

  • Lens angle is 75.4deg
  • Filter size is 77mm
  • Minimal aperture is f16
  • Minimal focusing distance is 28cm/11in

Performance

I gauged the performance of this lens in three different areas:
  • Low light performance
  • Color output
  • Wide angle

Low light performance

The Sigma 28mm features a very fast lens design at f/1.4. This makes it an ideal low light photography lens. Moreover, the mechanics of the lens also delivers incredible sharpness even at its widest aperture. I love photographing at wide apertures and am generally at f/2.8 or f/4.0. So the f/1.4 was attractive to me, especially in low light. I tested the low light performance at a couple of places in Chicago and was very happy with the results. The lens was also quite fast at focusing in these low light situations.

The interiors of the museum of science and industry in Chicago are quite dark but I was at ISO 320 and f/1.4. The 28mm captured the entire shuttle in the frame.

Color output

Sigma’s Art series is known for its superb color rendition, and the 28mm Art lens did not disappoint in this area. I tested the lens in a variety of lighting conditions, both indoors and outdoors, as well as on bright sunny days and overcast days. In each scenario, the lens output was beautiful.

5 Photography Mistakes You Need to Avoid When Shooting Seascapes

Here are some practical steps to take and 5 photography mistakes you want to avoid in order to help you capture better seascape images.
Capturing seascapes is a very popular past-time and one of the most enjoyable and fascinating types of landscape photography. People love to capture the ocean and for good reason.
Seas around the world are more accessible than ever to the majority of us. People take regular holidays to visit the abundance of natural beaches and the ocean provides a fantastic place of escape and freedom from bustling towns and cities.
beach and palm tree - 5 Photography Mistakes You Need to Avoid When Shooting Seascapes
The ocean is a breathtakingly beautiful place and offers peace, tranquility, and an ideal opportunity to capture some memorable images. While the coastline offers photographers spectacular seas and atmospheric skies, recording these scenes can be challenging.

Mistake #1 – Cloudless skies

A common mistake that is often presented in seascape imagery is a vast expanse of empty sky without any texture or formation from clouds to lift the image.
Seascape rocky shore sunset - Here are some practical steps to take and mistakes you want to avoid to help you capture better seascape images.
To avoid this pitfall, head to the coast on partially cloudy days. Photographing ocean vistas to include the different patterns and shapes of clouds above the sea will help your images to become more inspiring.
If you find yourself taking pictures by the sea during first and last light, you will discover the colors in the sky can look even more dramatic than at other times of the day. This can beautify your image with vibrant sunset skies igniting the sky.
Alternatively, capturing big white clouds to complement a blue sky or dark, moody and overcast skies can add drama and emotion to your images.

Mistake #2 – Not checking the tide schedule

If you are unprepared during a visit to photograph the ocean by not checking the tide schedule, you may get caught out by incoming tides and even freak waves during adverse weather.
The sea and waves can be unpredictable and powerful. I have ended up with wet shoes countless times while trying to capture the moving waves. Be mindful of the risks the ocean presents to you and the harmful impact the saltwater can have on your camera and equipment.
Always protect your camera (a plastic bag can keep it safe from the salty sea air) and be sure to clean your camera when you return home.

If you would like to capture the swell of the ocean at high tide or an exposed bay of rocks during low tide, be sure to check the tide times and visit at the right hour.
You will find that planning to be at the coast when the tide is at a certain point will help you shoot better compositions and seascape photos.

Mistake #3 – Not considering your composition

Capturing beautiful images of the coast is not as straightforward as you might think, especially if you don’t think about your composition carefully. A few things worth considering are leading lines and the rule of thirds.

Leading lines are a great way to lead the viewer’s eye into the frame toward the main focal point in the photo. They can help to create depth in an image and provide more purpose.
When photographing the sea, you will find that placing the horizon in the middle of the image will generally be less effective than positioning the water level above or below the center of the frame.
Seascape simplified - 5 Photography Mistakes You Need to Avoid When Shooting Seascapes
You may be asking if should you include more sea or more sky in your composition? Well, that depends on the nature of the scene in front of you and what is the most interesting and important aspect of the story.
If the sky is compelling and vibrant, your image will be stronger by including more sky. But if the sky is uninviting and lacks drama while the ocean is swirling beautifully, compose the image to include more of the sea.
Whatever you decide to shoot, be imaginative and creative with your composition and capture some great images.

Mistake #4 – No focal point

Seascape blue water and a fish - 5 Photography Mistakes You Need to Avoid When Shooting Seascapes
One of the great benefits of being by the coast is the variety of subjects to shoot. However, it is surprising to see the number of times beginner photographers take images of the sea without including a strong focal point in their images.
You could focus your camera on any number of interesting material at the sea such as piers, fishing boats, lighthouses, cliffs, rocks or fish.

Mistake #5 – Not including any foreground interest in the shot

While the sea can make an exciting subject, a mistake newbie photographers tend to make when capturing the ocean is to photograph the sea and sky with nothing in the foreground.
This can occasionally work well in the right light and setting.

But capturing an extra element such as cliff ledges, flowers, shells, or footprints in the sand will add context and another dimension to your image to help it stand out.

The best seascape images rarely happen by chance. Instead, they are the result of careful planning, diligence, and practice. Keep exposing, avoid these photography mistakes and use the tips and with plenty of practice, you will soon be capturing breathtakingly beautiful images!
How about you, what do you enjoy about seascape photography? Please share your tips and images below, as well as any questions you might have.

4 Less Popular Types of Lighting Every Photographer Should Know



How can you, as a photographer, best use lighting to your advantage? Working with different kinds of light can be a challenge for even the most seasoned photographers. This often leads to a common suggestion: “Point your shadow at the subject.” Yet certain underutilized less popular types of lighting can actually enhance your photographs.
macro photography bokeh flower dahlia - Types of Lighting
In this article, you’ll get tips for working with four different types of natural lighting, including shade, overcast light, and strong backlighting. Hopefully, you’ll come away with the know-how and inspiration to start using more creative lighting in your own photographs.
macro photography bokeh flower tulip - Types of Lighting

1. Shade plus front light

By “shade plus front light” I’m referring to the lighting situation when the sun is behind you (and coming over your shoulder), but the subject is shaded. That is, the sun would normally front light the subject, but it is blocked by an object.
macro photography bokeh flower trout lily - Types of Lighting
I shaded this trout lily with my body, resulting in a shaded subject and a well-lit background.
Many photographers like to ignore shaded subjects. However, I love this lighting situation for a few reasons.
The first is that it is easier to expose for a shaded subject. You don’t have to deal with intense highlights and shadows. Instead, you can rest easy knowing that the range of lights and darks in your image will be rendered properly by your camera’s sensor.
purple flower - Types of Lighting
Another shaded but front lit situation. Notice the brighter background here.
The second is that this lighting scenario offers up wonderful backgrounds. This is an especially powerful technique when shooting during the “golden hours”, the time just after sunrise and just before sunset.
If you can position the subject so that the sun falls behind it, you can take images with rich, warm background colors. The key is to expose for the main subject (i.e., meter off it), and let the background remain bright. Use a wide aperture to ensure that the background is thrown out of focus.
macro photography bokeh flower cosmos - Types of Lighting
Shading this cosmos flower allowed me to produce a more subtle looking subject with a
beautiful background.
Shaded subjects can make for great photographs if you know how to use them!

2. Shade plus backlight

To continue with the “shade” theme, let’s discuss another underutilized type of light: shade and backlight.
By this, I am referring to a situation with a shaded subject where the sun is positioned behind that subject so that you are pointed toward the sun. In this situation, you cannot do the shading yourself. Instead, you have to rely on environmental features to block the light.
macro photography bokeh flower - Types of Lighting
This flower was shaded by some nearby grasses. I was able to get these background
highlights by including the edge of the sun in the frame.
What does this type of lighting offer you? Similar to a shaded and front lit subject, a shaded but backlit subject is easier to expose.
If you’re struggling to photograph a brightly colored flower, for instance, it might be beneficial to find a similar specimen in a shaded area. This will help prevent you from blowing out the highlights on the flower’s petals.
macro photography bokeh flower aster - Types of Lighting
Another compelling reason to use this particular type of lighting is that it can create beautiful bokeh. I’m not really talking about bokeh in the sense of that smooth, creamy look that we photographers love (for that, go back to shade plus front light).
Rather, I’m referring to those beautiful geometric shapes that occasionally appear in the background of photographs.
macro photography bokeh flower tulip - Types of Lighting
Notice the slight highlights in the background, created by the shade-sun combination.
How do you do this?
In a backlit environment, the light is often filtered through the surrounding greenery. These are often leaves, but also grasses, shrubs, branches, tree trunks, etc. The rays of the sun are broken up into small points of light, which are then rendered in that geometric fashion when incorporated into your images.
This is a beautiful effect that can add an extra punch to your photographs.

3. Overcast lighting

This type of lighting is more commonly used than the two mentioned above, but overcast light (i.e., light on cloudy days) deserves a mention.
macro photography bokeh flower aster - Types of Lighting
I photographed these flowers on a cloudy afternoon.
You might think that the camera should stay inside on overcast days. After all, the subjects aren’t very well lit, and everything seems a bit gloomy and bland.
Actually, overcast days are fantastic for photography. Especially if you go out toward the middle of the day when the sun is high in the sky (and blocked by clouds), you’ll find wonderfully diffused lighting.
The clouds act as a giant softbox, subtly lighting the entire landscape. This results in colors that are deeply saturated. Macro photographers such as myself love overcast lighting because our flower photographs become much more colorful.
macro photography bokeh flower tulip - Types of Lighting
Another advantage to shooting on overcast days is similar to that of shaded lighting in that the subjects are easier to expose well. There is no bright sunlight to create harsh shadows and unpleasant highlights.
Therefore, overcast days can be a great choice for photographing brightly colored subjects.

4. Direct backlighting

Direct backlighting refers to situations where the sun is directly behind the subject (and therefore directly in front of the photographer).
macro photography bokeh flower tulip - Types of Lighting
The sun is just out of the frame here, above the tulip.
This type of lighting is difficult to work with. Photographers often come away with unwanted flare and a drastically underexposed subject. However, using backlighting is simpler than you might think. Just remember a few key guidelines.
The first thing to note is that I don’t like to use direct backlighting unless the sun is low in the sky. Otherwise, instead of achieving a charming, warm look, you’ll find yourself with a harsh, contrasty image. Sunrise and sunset are your windows, so you’ll need to work quickly and efficiently.
Second, don’t put the sun in the image itself. This will result in a nearly impossible lighting situation. Instead, block the sun with your subject. Move around a bit. Get down low. If you do decide to include the sun in the image, put it at the very edge of the frame (as I did in one of the photos above).
macro photography bokeh flower bleeding heart - Types of Lighting
Backlighting (the sun was in the background on the right-hand side) produced some really
interesting bokeh in this bleeding heart photograph.
Third, make sure that your subject stands out against the background. I often try to compose with the subject against the sky.
Fourth, expose for your main subject. Don’t worry about the bright background. Then, once you’ve settled on an accurate exposure for the subject itself, feel free to raise or lower the exposure. Lower it for a slightly darker, more dramatic look (and if you lower it a significant amount, you’ll end up shooting a silhouette). Raise it for a slightly brighter, in-your-face type image.
While there are certainly variations in backlighting conditions, these four guidelines will get you well on your way to shooting some creative backlit images.

While it can be difficult to think outside the box and take risks when it comes to lighting, the rewards can be great.
Try using some of the lighting scenarios discussed above: shade and front light or backlight, overcast light, or even direct backlighting.
Your images will become far more diverse and a lot more impressive!
