Canon EF 40mm f/2.8 STM Overview
|I own it||I want it||I had it|
The Canon EF 40mm F2.8 STM is a very slim, very lightweight pancake-style prime lens for both full-frame and APS-C Canon DSLR cameras. It features a stepper motor for fast, quiet focus, particularly important with the contrast-detection method of autofocus used for live view and video. Its optical construction includes an aspherical element and coatings optimized to reduce flare. Its closest focus distance is a mere 30cm, and a circular 7-bladed aperture ensures pleasant rendition of out of focus areas.
The EF 40mm f/2.8 STM is a lens whose impressive image quality belies its low price and tiny size. For APS-C users it's a tiny, inexpensive companion to a kit zoom, and on full frame it offers a great option for general shooting. It's taken a while for Canon to come to the pancake party, but the 40mm takes its place alongside its peers as one of the best examples of its type.

The EF 40mm F2.8 STM offers excellent image quality in a tiny, well-made package. For APS-C users it provides a great carry-everywhere complement to a kit zoom, and for full frame shooters it's an excellent general-purpose 'normal' lens. The STM motor means that autofocus is almost completely silent, but it's not super-fast.
Good for: Canon SLR owners who want the image quality of a prime in a tiny, relatively inexpensive package.
Not so good for: Photographers shooting in really low light or aiming for maximum background blur. They'll do better with a faster lens like the EF 50mm F1.8 II.
