Canon 50mm f/1.8 STM Review

Canon is known for their hundreds of unique and superb quality lenses. In March 2015, Canon updated their most famous, favorite and best bang for the buck lens, the nifty fifty, or 50mm lens. You can grab this lens for just around hundred dollars, and it captures professional quality images. Let’s see more details.

Visit my Buying Guide pages to learn everything about lenses and cameras. 



Focal length: 50mm

Maximum Aperture: f/1.8

Focusing motor: Stepping Motor (STM)

7 Diaphragm blades

There is nothing special about it, but there has been major updates from previous generation. There is now seven diaphragm blades instead of five. This will allow photographers to create much prettier bokeh! In addition, focusing motor has been updated to STM, which will allow quieter and faster focusing system.

Build Quality

Previous generation 50mm had serious problem with its longevity due to its plastic mount. However, Canon fixed this issue on updated lens by using the metal mount instead of the plastic. Sadly, it does feel very plasticky, maybe because it’s super light. I’ve accidentally bumped this lens into many walls, but it seemed like it’s pretty solid. It’s hundred dollars, you get what you pay for. 

Image Quality

You may think the image quality of this lens is poor due to its cheap price, but you are wrong. As I mentioned in Choosing a Right Lens, prime lenses tend to provide superior image quality due to fewer elements, or fewer glasses, in the lens. This lens can capture sharp and beautiful images. Here are some examples.

 1/10@f/1.8, ISO 100
1/10@f/1.8, ISO 100
 1/640@f/5.6, ISO 100
1/640@f/5.6, ISO 100

This lens have endless abilities. Wether you are a street photographer, a landscape photographer, or a photojournalist, this lens will satisfy you. 


This lens deserves to be called “nifty fifty”. It’s cheap and packed with performance. For hundred dollars, I don’t think there is any lens that can defeat this one. If you don’t have it? Give it a try, like I did, and you will keep it because it’s an amazing lens. 

It’s Christmas eve today, and if you know someone who likes camera, take this lens to him or her as a Christmas gift and they will love it.
