    Cons: Manual focus is possible, but with a tiny focus ring, isn't happening. Annoying CA no matter the aperture. Only in bright/contrasty situations though. Usually neglible in most situations. Wouldn't worry about it too much.

    Pros: Light weight, fast, cheap, build quality, silent focus, sharp and useful wide open.

    Summary: This is one of the hidden gems in the photography world. It's image quality per ounce coupled with its performance wide open is unrivaled. People trash talk Canon M all day long so this lens doesn't get the attention it deserves. Other mirrorless APS-C lenses its size are 2.8 and not as sharp anywhere in the aperture range. Typically large aperture prime lenses are soft wide open and only useable stopped down. Not this lens. Not only is it fast (actual t-stop is around 2.3 I think) but it's sharp corner to corner. Stopping down does not noticeably make things sharper. So coupled with the large APS-C sensor, the Canon M and this 22mm packs a powerful punch in hand held low light that is pretty much unrivaled in its class. Just watch out for bright/contrasty scenes as you will get purple fringing even when stopped down. Not a big deal though most of the time.

    Cons: unobserved

    Pros: no need for a tilt shift as this lens has virtually no distortion, DXO says 0, single digit CA, razor sharp center with an f2 aperture. f2 at 22. Where else does this exist with these qualities. Zeiss for thousands is as close as it comes. Use it outside or inside in any light as the M has CA correction, ISO noise reduction, Distortion correction and HDR if you were shooting with a lens that needed any of that, which with the 22f2 you're not. Some one some where said the M had slow AF and everyone wrote off the M system. For me it's worth it to own an M just to have this lens. It's become the only crop sensor I carry as, with an adapter, it's the only camera I enjoy short of full frame. What's not to like? All my best glass on a pocket sized gem that has a Digic 5 sensor and touch screen!

    Summary: You'll never regret owning the 22f2 or the M. I own the L85f1.2M2, USM100f2, Zeiss 135f2.8, L70-200f4is, 50f1.4, and a great many classics and they are all in the bag as the 22f2M gets all the work until I think I need to take the time to stop and set up my 5DM2 or my M with something bigger, which is not often. With the quality of crop I get from the 22f2 on the Digic 5 I seldom need to reach for anything else unless I'm setting up for dedicated portraits or birding. I think the Sony A7ii with the in body stabilizer and an EF adapter will be the next purchase as I am interested in the L85f1.2M2 wide open and stabilized but that's not something I'll take everywhere I use the 22f2. Good shooting and remember to thank me.
