I’ve received a Canon EF 40mm f/2.8 STM Pancake Lens. At about $199, it’s attractive for its compact dimensions and ultra-light weight, and thus might make a handy “normal” lens for all-around shooting on Canon DSLRs— slightly wider than a 50mm. It fits very nicely on a Canon 5D Mark III.
On a Canon EF-S camera (1.6X crop), the lens is equivalent to a 64mm lens, and is perhaps a bit less versatile than the 40mm angle of view, but as a short portrait lens, why not?
I’m a little puzzled about the “continuous focus for video” claim, since the lens makes a high-pitched noise when focused, which surely will be picked up by a microphone.
I’ll have more on the 40/2.8 STM in DAP in due time.
