I can’t comment on the AF speed of the Z7, but I found that my Z6 was no worse in C-AF performance than my E-M1 II. It’s still not at the level of my D500 though, so when shooting action I always have a D500 with me (the camera that originally began pulling me away from my Olympus gear).Thanks Ian. I'm liking both the camera and the quality of the images from the Z7 and its lenses so I'm definitely here to stay for a while. I'm going to go cold turkey with it and leave the Oly gear in the cupboard. If after a month I've not had any need or desire to go back to it, then it's off to eBay for my landscape trio (8mm f1.8 FE, 8-18/2.8-4, 12-100/4). I'll then get the 24-200.
That'll leave me with the EM1.2 plus 40-150 + TC for long lens use. I may at some point replace that with the 70-300 AFP since I'll get cash back on the deal and will get pretty much the same reach, but obviously down a couple of stops on aperture which the better ISO performance will make up. Anyhow, time will tell. The EM1.2 is a very fast camera, much faster than the Z7 so I may stick with it.
I have the 70-300 AF-P, and it is a very impressive lens given it’s price. Fast AF, optically sharp, and light weight (plastic body).
