M43 with f1.7 and 3 axis IBIS versus canon apsc with f2. Which is better in low light? Looking for trouser pocketable camera that is better than a 1" compact. Specifically the e-pl9 vs m100. Both are under 40mm. Add pancake around 60-70mm. The Canon has a bigger sensor and more megapixels and I like to zoom into pictures. However, the e-pl9 has IBIS which helps with the smaller sensor and videos look much better with it. I also like olympus color more. It would've been easier if there was an e-pm3 or something. Not into the panasonic look.
I shot Canon for many years, I even have a Canon EOS-M + 22mm f/2 before I switch over to M43. In my experience with lowlight:
Olympus E-PL9 (with 16mp Sony sensor) is superior to Canon in lowlight,
Canon, both 24mp or 18mp, is better than Panasonic in lowlight
But once you factor in the 3 stop IBIS advantage, it becomes a definite win for Olympus E-PL9
Keep in mind that Canon M100 don't have IBIS, and Canon 22mm f/2 prime lack stabilization. Still, I'm quite happy shooting Canon 22mm f/2 in lowlight without stabilization: smaller the camera, easier it is to hold without stabilization.
16mp Sony sensor in Olympus is quite good, I prefer it over both Canon 24mp and 18mp due to its slighlty cleaner iso3200 performance, where I shoot mostly. I'm comfortable using iso3200 with Olympus, with iso6400 as last result. The biggest advantage in lowlight is that Olympus has 3 stop IBIS. That means under these same conditions of extreme lowlight:
Canon with 22mm f/2 (no stabilization), I have to rely 100% on high iso. I dont' find iso6400 tolerable for my portait photography: too noisy result in poor skintones, so I will rather under-exposed @iso3200 then post-processing to brighten the image with noise reduction.
Where as Olmpus E-PL9 (under the same condition) in theory can be shot @3 stop lower. That means instead of noisy iso6400 → iso3200 → iso1600 → iso800, I can shoot @much cleaner iso800 without noisy images.
These are just theory, in real life, I'm more conservative with 2 stop estimation. Still, that means I can shoot @iso1600 (very clean) without worrry.
Canon biggest advantage is in Dual-CMOS-AF for superior Video Tracking for Vlog. If you Vlog, forget Panasonic or Olympus, just stick with the Canon. For still, shooting, I'll take either Olympus E-PL9 / E-PL8 / E-PL7 over Canon M5 / M6 / M50 / M100.
Canon 22mm f/2 is a great lens, but it also FLARE quite easily and doesn't have a lens hood to prevent lens flare.
