It's not about equivalence (i don't care for that and never think about it when using APS-C or full frame) but can MFT cameras do birds in flight as good as dedicated SLRs ?

All my previous cameras were not spectacular, 300D, 30D slightly better but not impressive, 5D was the same, 750D was an improvement but 7Dmkii is on another planet, so for me no going back.

Can good MFT cameras perform as good as 7Dmkii or Nikon D500 for birding ? You know for birding stabilisation is pointless or even harmful, and more DOF is a plus ☺

Tony, of course MFT can do birding. Depends on the camera of course, EM1mk2 or GH5 would qualify as best in MFT land, and for example my Pana G7 is far from being inadequate. I can’t tell how it would compare to cameras you mention, however I can throw in some AF experience of my own.

I do use a lot of AFS and certainly this is the area where the camera excels. With AF accuracy, ability to position AF point anywhere in the frame, and instantly via AF touchpad, it won me over.

At continuous AF, birding I did few times only, more I do some sports and family stuff. No question there are more expensive cameras out there that do better in AFC, but 500€ G7 with 35-100/2.8 can bring keepers home rather easy.
