Canon EF 50mm f/1.8 STM Lens Review (With Sample Images)

Canon 50mm is one of the most popular lenses in Canon family. 50mm f/1.8 STM is a long-awaited replacement of 50mm f/1.8 IS II. Canon announced 50mm f/1.8 STM in 25 years anniversary of Canon 50mm f/1.8 IS II. 50mm f/1.8 IS II was the madly popular lens.  The 50mm f/1.8 STM comes back in the market with an extreme level of sharpness. The lens design with EF mount and will also work on EF-S mount.

Earlier the Canon 50mm f/1.8 IS II is enormously successful for some key reasons. Flexibility and brighter aperture are the main reason. On the other hand low price of this lens is a factor behind of its popularity. The new 50mm STM Is small, lightweight and has a decent build in quality. It has a metal mount.

The Canon 50mm STM is a brilliant looking lens with an AF/MF switch and a thin focusing ring. The focusing ring of new STM is smooth and wider than 50mm IS II. Canon produces two types of STM lens. One is Gear  Type, and another is a Lead Type.

Lead type is too good to focusing and in virtual silence. On the other hand Gear type motors are smaller but focusing very slowly with some sound. 50mm STM made by Gear type motor due to its size.  But it’s undoubtedly smoother and quieter than its predecessor.

What do you think there is a huge difference between 50mm IS II and 50mm STM? If your answer is YES, then you are in the wrong. Because there is not so huge difference between this two lens. 50mm STM is same optics design as 50mm IS II. Don’t be so disappointed.

Canon introduces the same optic design of 50mm STM as 50mm IS II.  But two new features included in 50mm STM. These two features change the image quality of 50mm STM. Canon promised Super Spectra Coating and optimized lens replacement and flaring than the previous model. At the same time, it enhances the quality of light transmission and color accuracy.


The lens minimum close focusing distance is just over 13, canon” and at this minimum distance, it provides you a magnification of 0.21x – not enough good for macro but not so bad at all. So one can try macro photography by this low price lens.


This is one of the cheapest lens Canon lens family. This inexpensive lens gives you outstanding performance. If you think about zoom lens then this lens not for you but if you want a quality lens in affordable price then 50mm STM is the best choice for you. Here is some online price list:

Here I show some photo taken by Canon 60D with 50mm f/1.8 STM. In my point of view, this one shows really mind-blowing performance in daylight and low light.



Over To You

This one is very low price lens but you can go for it. Beautiful portrait and landscape can take through this lens. Aperture f/1.8 value gives you a nice blur background in the portrait photo. So you can try it.
