Zoom and M4/3rds v crop and FF for wildlife?

[woof woof]

The problem is this isn't really a like for like comparison. Generally a FF camera cropped will give better IQ, but it usually comes at significant cost and larger camera/len combinations.

I never had FF but told my APS-C DSLR for a micro 4/3 system as I found I wasn't using the DLSR because it was too bulky to carry everywhere.

Whilst the IQ may be lower in my micro 4/3, at least I have the shot as I'm more likely to have the camera with me.

I think you have to compare the specific camera body and lens combinations you're interested in as unbelievable as it seems some MFT and APS-C camera bodies are bigger than some FF bodies. For example the Panasonic G9II is bigger than my FF Sony A7III and A7cII. I mostly use wide to normal primes and when I have a compact one fitted to one of my Sony cameras there not enough bulk and weight saving to make my MFT GX80 worthwhile.

I think the main difference doesn’t show with long range shots ,but when you get a subject that is frame filling with MFT you get a sharp shot but with a high mp FF camera you get a sharp shot plus lots of fine detail ,it’s a subtle difference but once you notice it you can’t overlook it

I bought the S1Rii earlier this year after previously owning the MK1 version which I loved. I changed systems to the Nikon Z8 from the Mk1 as I was getting back into wildlife photography and didn't like the blackout of the EVF.

Imo the S1Rii blackout wasn't much improved over the Mk1 version and I returned it. I paired it with 24-105mm kit lens which was excellent and a Sigma Sport 150-600mm lens which was also excellent.... If I was you, I would rent a S1Rii before making the purchase to make sure it's suitable for your needs. YMMV to mine.

Interesting regarding the evf blackout on the S1Rii as there is no blackout on my S1iie, and they're both advertised as blackout free when using electronic shutter.

I have noticed that the AF isn't as accurate when tracking in electronic shutter to normal, but I never noticed evf blackout, something I'll look for more next time.
