Thats the thing, Im also always asked if I can use my "fancy camera" to capture family photos outside when everyone is leaving, having the wide angle plus the ability to shoot a bit faster might be useful.

Im mostly concerned about being able to take photos of shops and buildings in the dark, so not totally low light. (personally im night blind, if I cant see I know the cameras sure cant lol)

actually, you bring up a point where your m200 in low light would struggle achieving auto focus by 3 stops worse than the m6II and by 2 stops worse than the m50II

The M200 is only one stop worse than M6II and same as M50II

if buildings in the dark are your application, I'd be concerned about the -2 versus the better low light bodies (-5 and -4)

M200

EV -2 - 18 (room temperature, f/1.4, ISO 100,

That is not true. It is EV -4 - 18 (room temperature, f/1.4, ISO 100, One-Shot AF)

I don't know why you post stuff like that?

I misread and posted movie mode by mistake

Canon EOS M200 Specifications (the-digital-picture.com)

that said, op can test if their 22 f2 at f2 focuses on dark buildings and if so, the 16 should be 1 stop better for 1/2 the light needed -- but I still wouldn't buy the 16 to shoot dark buildings handheld

With DxO Photolab and DeepPRIME it could be possible. Here's a link to Amtrak trains I shot with the Sigma 16mm f1.4 in very low ambient low lighting with the M6 Mark ii which does about 1/2-2/3 EV better than the M200 or M50ii in low light. In the samples I pushed to some extreme ISOs like 25,600 - 51,200. I had to shoot at around 1/200 sec to freeze the train. ISO 6400 is no problem with DxO DeepPRIME and the M200, and you may be able to push at least to ISO 8,000 - 12,000, depending on how much detail you need in the shadows.

impressive!

were you on tripod?

No, there is no time to set up tripod when chasing trains at night on bicycle! Besides there is no need shooting at 1/200s with 16mm focal length.

I've also pushed video to the extreme ISOs at night shooting trains. I created a special monopod rig that can hold 2 M6ii's, one with the Siggy 16mm and one with the Roki 135mm f2 and a speed booster, for wide and telephoto f1.4 simultaneous shooting. I can break down and set up the monopod from my large-ish camera bag in under 30 seconds, it comes apart into just 2 pieces.

I shoot in 4k, stabilize and process each clip with with Adobe Premiere, and downsample to 1080p to reduce the noise. It should work just as well with the M200 but it would be limited to the M200's 24 or 25 fps, not 30 fps, at 4k. See this post

Thanks!  Good Stuff!  Makes me want a 16!

M6II

EV -5–18 (at room temperature, ISO 100, f/1.4,

M50II

Working Range EV -4 – 18 (ISO 100 equivalent with F1.4 lens attached)

note - your m10 is even worse at EV of 1 at f2 which would be EV of 0 at f1.4 - that is a whopping 5 stops worse than m6II

Working RangeEV 1-18 (at 23°C, ISO 100, with EF-M 22mm f/2 STM)
