D600 upgrade

[Frank F.]

Am I right? Should I just get another D600, or can I get better ISO performances with the D800 or DF?
Thanks in advance!

A second D600 has a lot of PROs and very few CONS.

PRO

1) dirt cheap for what she can do
2) identical control layout to the D600 ;-)
3) batch editing over both cameras with large sets of pictures

CONS

The fifth generation cameras are so darn good in all the stuff the D600 sucks at (I used her professionally on a daily basis for 4 years, I know her inside out. Great piece of hardware & I used her professionally on a daily basis in parallel to the D500 for one and a half years until I got the D850 which smokes the D600 but not the D500, these are next to even).

So if you manage to shell out the money for the D500 at least you get all the benefits plus:

ISO up to 20.000 perfectly usable
Never before seen in a Nikon AF-Performance
Never before seen in a Nikon WB-Performance
10 frames per second professional sports shooter
gripped you get battery longevity to dream of
gripped you get ergonomics better than the D5 (yes, I used the D5 long enough to know!)
XQD blasting memory performance and buffer size
Very silent operation
Combination of DX & FX in your setup, so two "meanings" to every lens you own

Try to catch a sale on her or find her used. I recommend this shop: Nikon D500 Digital SLR Camera Body (Kit Box) to compare prices at least
