I have been a Nikon and Fujifilm shooter for years. I used to have Nikon DSLRs, and switched to a Fujifilm X-T1 years ago because the smaller size and weight appealed to me. I quickly upgraded to an X-T2, then added an X-H1 and at this point the cameras were pretty large, my lenses were too and the autofocus accuracy when adapting my Nikon F mount lenses with a smart adapter wasn't great. So I switched to a Nikon Z6, which wasn't larger and "fixed" everythinhg, but then I also realized I was still lugging around full frame lenses and though my camera was substantially smaller and lighter than my old D700, the lenses were just as big and heavy.

In parallel, I bought into micro four thirds as a little fun side system I would use for travel and casual occasions with an E-M5 mark II. The lack of good C-AF pushed me to splurge on a better performing body in June of this year, and since I'm a bit stingy and didn't want to spend 650 bucks on an E-M5 mark III, I dropped 400 on a slightly larger E-M1 mark II.

After using it for a couple of weeks, the realization came : this camera does everything I want a camera to do. Sure, low light isn't as good as my modern full frame body. But I shot concerts in nearly pitch black conditions and the E-M1.2 handled fine, I was even able to give the pictures to the artists that played that night and they reshared those pics on their social media happily. I, as a camera enthusiast and technical nerd wasn't really able to find many cracks in the low light performance of that camera, and I'm pretty sure that non-photogs wouldn't even think twice about the amount of noise or slightly blown out highlights. Similarly, every fast paced action stuff was just as easy to capture on my E-M1.2 as it was on my Z6, with an AF system that is comparable in performance, Pre-Capture, 18fps bursts and a rolling shutter effect when using electronic shutter that is manageable to the point that I don't hesitate to shoot action with it if I need the faster burst (thing I would never do with the slow-ass sensor in my Z6).

For my landscape work, at first I was doubtful : the sensor has less DR, and a lower resolution. Then I realized I do most of it on a tripod when I really need good resolution anyway, and at this point why not use the Pixel Shift mode? The DR increase you get is more than making up for the smaller sensor, which I don't have to close down nearly as much for good sharpness and DoF, and the 80MP files don't hurt either. Overall, it's a better landscape camera tool than the Z6 was, which is very high praise coming from me because the sensor in the Z6 is incredible.

On the video front as well : autofocus is great, 4K quality shooting DCI-4K in 8bit with the OM-Log400 profile is absolutely great and I have completed several projects with it without a hitch. The camera doesn't really overheat, the IBIS is exemplary, the audio pre-amps are better in every way then those on my Z6 too.

And then there's the lenses. They simply are awesome : sharp, small, lightweight for the reach they provide, and they are affordable. I wasn't sad in the slightest trading my Sigma 100-400 full frame lens for an Olympus 75-300mm lens to shoot airshows with. The prime lenses are also exemplary in the value they provide, I'm particularly fond of the Lumix 20mm f/1.7, Oly 45mm f/1.8 and especially the Oly 75mm f/1.8, this lens is a beast.

After a couple months using the E-M1 mark II, I came to the realization that that camera is as good or better than my Z6 in pretty much every area. At no point was I using that camera and thought "man, I wish I had the Z6 right about now". On top of that, I could share the lenses with smaller camera like my Lumix GF7, or turn the E-M1.2 into a really small package by using a small pancake lens on it (paired with the Lumix 14mm f/2.5 it's a silly looking camera, but very effective for street photography and sticking the camera into minuscule bags). I can't do that on Nikon Z.

I took the decision to sell the Nikon Z6 early next year (right now it's going for a long time loan to a friend of mine that wants to test out full frame), and as such need another camera with good AF and good 4K video as backup / second body for events. I initially thought about getting an E-M1 mark III with the money, since it goes for about as much money as I would get by selling the Z6, and it has some nice little improvements over the mark II. But prices are not coming down, and MPB listed that E-M1 mark II for 284€ (instead of the average 500ish) because the screen has a very small crack that's barely visible, so I jumped on that, and now I have two of those.

I fully intend on using both of those bodies until they break down in my hands, or I get the itch again and upgrade to an OM-1 (mark 1). Even then, I think I'll keep at least one E-M1.2 as a backup / second body. They're that good, and probably the best price to performance ratio to features you can get in micro four thirds. Extremely underrated.

The funny part is that it was on my recommendation list when people were asking me camera questions, I have several friends that ended up buying one in the last 2 years and were extremely happy with it. I guess it finally creeped on me !
