I just bought the camera yesterday, and looked online for tricks. I have the "AF-ON" button programmed for 200% magnification. Easily reached, zoom-in, focus, hit the button again for full-frame. Will not work for moving skaters in the Dark! I also turned the focus peaking to max sensitivity- which comes close to the zoom-function. I am getting used to this camera. First new camera since buying my Df. If Nikon comes out with a FX (corrected) format Zf, I'm getting it! BUT- at under $1K for the Z5, the Nikon F3HP that I just sold paid for it.
