A while back, I posted here for advice on replacing my D5300 with a D7500. I mentioned that I rely mostly on modes like "sports" (race cars, air shows, birds) and "landscape", and some "manual" shooting (rocket launches, lighted bridges at night). I was happy with all of the D5300 results, except most of the night shots.
I received a lot of help here. The discussion was mostly about the benefits of the D500 but there was also some discussion on the D750 (possibly better performance in low light and certainly better portraits) - and the excitement of going FULL FRAME.
I eventually decided to buy TWO: A used D750 for portraits and landscapes and a new D500 (with the 16-80mm lens). I also own DX lenses: 18-300mm f3.5-6.3G, 35mm f1.8G and an FX 80-400mm f4.5-5.6G.
I've been shooting with the D750 for a month, mostly beach birds, seeing some better color (than with the D5300). But I am missing the extra "reach" (DX crop-factor). I'm just about to pull the trigger and buy the D500 AND HAVING SECOND THOUGHTS. My concern is that it doesn't offer the "sports" mode that I've used so successfully (race cars and fast moving jets). I'm worried that I may not reach the proficiency level to find and approximate those settings -- and even if I can figure it out, the D500 doesn't allow me to save all of those settings. That would be $2k spent for race shots that I may never be able to get.
Can anyone with experience (D500 and race cars or jets) share advice on this? Should I consider a lesser camera (ie: 7500) just for the sports (and some wildlife) shots and defer to the D750 for everything else?
