This thread is my introduction to the D7500, 10 minutes ago I had no idea that it was coming. Having said that. I have to remark on Ilkka's remarks, which hit home for me.
I have a D200, and for me focusing the 105/2.5 ais has been a problem. So much so, that I don't mount the lens on the D200. As Ilkka said, the F100 and F3HP were easy to focus with that lens. Remarks from other DX users have not extolled the virtues of non-cpu lenses on DX models, and AFAIK, that is a major problem. Nikon's non-cpu F mount lenses should not present focusing issues on any Nikon model, IMO.
Ilkka is right again about folks looking at used models when the hobble a D7200 replacement as they have donw with the D7500. No thanks, not for me. In fact, with the bon-cpu lens focusing issue for DX, I'm just not excited about replacing my D200 with a later DX model. Admittedly, I have not shot with any DX model newer than my D200, so I have no personal experience. OTOH, I'm not likely to get any such experience.
The way things are going with Nikon, I'm probably out of the camera buying market.
