Hey everyone, I currently take alot of landscape, but also love to carry my camera around for some street and travel photography. I love my Canon 22mm for its low light performance but I was wondering if it would be worth having the Sigma for the extra bit of light it would let in. Of course alot of photos would be in the daylight, but I don't really want to put the camera away when walking around outside at night. Would it keep my ISO down much lower?
depends
if shooting motion, yes
if shooting stills, the 11-22 with IS is what I would use
the 16 is a big lens - you have a small m200 - many use the 16 on bigger m bodies like the m6II or m50 II
I view the 16 f1.4 as a party lens to photograph kids indoors at f1.4 - sharp in the center at f1.4
outdoors at night, for stills, use the IS on the 11-22
outdoors at night, for motion, the 16 f1.4 would give you 1 stop of light, iso 3200 versus iso 6400, over your 22 f2
Re: 22 f2 vs 11-22 f4-5.6 IS
Your saying the 11-22 would be better than the 22 outdoors at night, for stills? IS would help that much with both at 22mm?
11mm = f/4.0
12-14mm = f/4.5
15-18mm = f/5.0
19-22mm = f/5.6
Canon EF-M 11-22mm f/4-5.6 IS STM Lens Image Quality (the-digital-picture.com)
handheld, with the 11-22 you get 3 stops of IS
that is the difference between f2 on the 22 and f5.6 on the 11-22
so then it becomes can you handhold the 22 at the slower ss
Is the three stops with IS really true? I'm just wondering about the real world use.
by a tad - Bryan found 1/3 of a stop less than 3

"in practice, I find that the EF-M 11-22mm delivers about 1/3-stop less than the specified 3 stops of improvement in shutter speed. Standing indoors on a stable floor and shooting freehand, I am seeing a good percentage of sharp images down to a 0.4 sec. exposure at 11mm and 1/5 sec. exposure at 22mm. At slower shutter speeds, the percentage of in-focus images drops, but it’s worth noting that a few sharp images were obtained at exposures as long as 1.3 sec. and 1 sec. at the wide and long ends of the focal range, respectively."
