Our take on the Canon EF 40mm f/2.8 STM

by Woody Sherman

If you own a Canon DSLR, this lens will fast become part of your essential traveling kit. Its "pancake" profile and low weight make it too portable to ignore, and when you add Canon's impeccable build quality and the lens' light sensitivity into the equation, it all adds up to "I have to have one."

You can shoot a huge variety of subjects, near and far, with this lens due to its versatile fixed focal length: 40mm on full-frame sensors/35mm film cameras, and 64mm on APS-C sensors. And the newly designed stepping motor for the autofocus system is incredibly quiet, making it perfect for video capture.

    Great Little Lens

    Written By FredW, Kingsport, TN on Tuesday, July 17, 2012
    Crutchfield Customer Review (What's this?)
     
    I purchased this lens to use on my 5D Mk3. It is the perfect small lens. It is small, light, and fast with extremely good image quality. Focus is fast, contrast is high, and corner to corner sharpness is great even at f2.8. I plan to use this lens indoors, as a walk around or anywhere that I don't want to carry my 24-105L.
    Pros:
    Sharp corner to corner Very low CA Very low distortion Good focus speed and manual focusing override Very little vignetting at f5.6 and narrower.
    Cons:
    Fair amount of vignetting at f2.8 Some vignetting at f4.
