I'm thinking to upgrade my D5100 for three reasons -
- More pixels
- Quieter shutter release
Right now the D7500 is the front-runner because it still supports my DX lenses, and I do take my camera outdoors in many types of weather so the environmental sealing is appealing. The better auto-focus is nice and the higher ISO and higher shutter speed are also appealing since I do find myself taking pictures in some extreme lighting conditions.
One feature I can't tell about, is the quiet shutter available on some of the Nikon FX format cameras like the D810 and D850. Do any of the DX format Nikons have an actual quiet mode? I don't mean the fake quiet mode like my D5100 has, where all it does is split the two kerchunks so they don't happen at the same time.
