Review – Canon EF-S 24mm f/2.8 STM Pancake

Review – Canon EF-S 24mm f/2.8 STM Pancake

By Canon Rumors | June 15, 2016 | Canon Reviews

Dustin has completed our review of the very affordable Canon EF-S 24mm f/2.8 STM pancake lens for Canon APS-C DSLRs.

Judging by the sales numbers for certain APS-C camera bodies from Canon, there are still a lot of crop sensor shooters out there, which is a great thing. The EF-S 24mm f/2.8 STM is a lens all APS-C Canon shooters should have, and at just $149, it’s an absolute steal.

Dustin’s observations:

It is rare that I refer to a lens as a “must own”, but I see no reason for a person that shoots crop sensor bodies (Rebel Series, xxxD, xxD, or 7D/7DII) to not own this lens. This is perhaps even truer if you own Canon’s diminutive SL1 body. The Canon EF-S 24mm f/2.8 STM has it all. Extremely compact size, a fairly large maximum aperture of f/2.8, great sharpness at all aperture values, fast focus, and a great, highly useful maximum magnification value of .27x. The bokeh is pretty nice (if a bit busy in some situations), distortion and chromatic aberrations fairly well controlled, and even the flare resistance is quite good. Read the full review

I use this lens quite a bit on my EOS 80D, which is a great combination of size and performance.
