I'm taking a work trip to Africa this Fall, and was going to us that as an excuse to upgrade from my D5200 to a D610 for wildlife photography over there.
With long lenses, high shutter speeds and narrow apertures I was looking for better ISO performance.
Would the D610 still be the better choice, do you think? I'm thinking that I might be able to save enough in lenses (DX over FX) in the long run, to make the higher pricepoint worth it. But will the ISO performance of the D500 be that in the ballpark of the D610?
I'm a big fan of the D610 personally (I like it better than the D750 for me), but when you combine "long lenses" and "wildlife" in the same statement my first thought is DX body.
The D610 is certainly cheaper than the D500 at this point, so while the D500 is improving in the low light capabilities over previous DX bodies, the D610 can be had for less. But ... if you're needing the reach of a DX sensor combined with long lenses, you might prefer the D500 more than cropping the same images off the D610.
I would contemplate whether a single trip to Africa is enough to justify a new camera purchase (vs renting a more appropriate body if needed), and look at what suits the rest of your shooting needs before deciding on that one. Then again, I tend to over-analyze and then make impulsive purchase decisions anyway, so I may not be the best advise guy.
