This lens is an update to the popular and inexpensive standard 50mm f/1.8 EF lens , replacing the standard focusing motor with Canon's new stepping motor technology, which promises smoother, quieter autofocus performance, which is especially suited to recording video.

This lens is situated as the next Nifty Fifty in Canon's line-up, offering the popular 50mm focal length at an affordable $125 price point. Of course, on APS-C cameras like the Canon EOS Rebel series will provide a field of view equivalent to an 80mm lens on a full frame camera.

Must have lens for every amateur

Sharpness is acceptable wide open, very good from 2.5 onwards; Lightweight Useful focal length on both crop as well as full frame

Compact and lightweight-an outstanding walk-around lens-Canon's EF 50mm f/1.8 STM is a great entry into the world of EOS prime lenses. With an 80mm effective focal-length on APS-C cameras, 50mm on full-frame cameras, it's an excellent prime lens for portraits, action, even nighttime photography.

Ask any Canon user what they think Canon's most popular lenses are, and I can guarantee that most will mention the classic EF 50mm f/1.8. Not only is it the most affordable lens in the EF line-up, it's also well matched to a wide variety of photographic genres.

It's a small lens that goes large in value for money and still manages to deliver some great quality...

Extremely light; Fantastic quality for the price; Much-improved handling

Honestly I can't remember how many 50mm lenses I reviewed during the last few years but there were many. Seems as if all the manufacturers are or have been in an update frenzy. All of then Well, Canon has been a little late in this game.

It's probably not as sharp as some people would like when used wide open, but stopped down to ƒ/2.8 or ƒ/4, it's as sharp as sharp gets. For the price point, you really can't go wrong with this lens, and it's a welcome improvement in sharpness over the previous version II of the 50mm ƒ/1.8.

This lightweight and compact lens offers more than just affordability; it gives you pure value for your money. The silent stepping motor allows for speedier and quieter autofocus, and the lens also delivers supreme quality images, robust exterior, and less motion blur at a bang for the buck.
