#8. "RE: upgrading from D300" In response to In response to 1 Mon 11-Mar-13 03:29 AM by JPJ
This has been discussed before but it can be both the 'flagship DX' camera and a 'middle class DX format D-SLR'.
The middle class reference could indeed be a reference to where Nikon places the DX format in their hierarchy of cameras between the p&s/mirrorless class and FX.
I wouldn't read much into this either way. There is simply no way of knowing whether Nikon will release a D400, we all have speculated one way or the other, but the reality is no one knows.
For me the biggest question of whether to upgrade now is to ask if the new camera will let you take better pictures. If you need a high buffer/fps camera then the d7100 may be a hindrance. If however you don't need that, and don't mind a few things being altered via menu vs. dial or button, then there could be a lot about a d7100 that would allow you to take better photos. The increase in MP and removal of the AA filter means you can really maximize sharpness in your photos. This doesn't come without a cost though. You will need good lenses to take advantage of the MPs, and a steady hand/ higher shutter speed to avoid it recording camera shake that might have gone unnoticed on a camera with less MPs. More MPs also means more cropping ability and, if you don't crop too much, bigger prints. Also no AA filter means moire could be an issue, see the D800 forum for a good thread on this re: the D800e.
You also get a camera with probably at least a stop to stop and a half better ISO performance. Especially when down sampled to a 12MP image as your D300 would give you. Additionally the increase in color depth and dynamic range in the new DSLRs is quite stunning vs. the previous generation.
