I'm principally a travel photographer and want a camera that's built like a tank. Part of the reason I bought a D300 in '08 the first place is my old film camera died after being drenched by waterfall mist in Costa Rica. The D300 was a no brainer. I haven't looked at cameras since, but with all this excitement about the D750, I had to check it out. I gotta say, I was a bit disappointed. The D750 seems to use cheap plastic parts for the dials and many of the other material choices don't seem to match up to the D300. On one end of the spectrum, the D800 appears to be a better build, but didn't blow me away (I prefer the D300). At the other, the D7100 seems to have about the same build as the D750 at half the price. Since I don't need/want FX, the D7100 appears to be the best choice of the three. Unfortunately though, when I consider the additional pain to change accessories (different batteries, different memory cards, different ball head mount, etc) and a less robust camera, I'm not so convinced. Sure, I'd love to have more pixels for crops and the improved DR, but it may make sense to hang on a bit longer for something special to come around. After all, I still get some great shots and (if I'm honest with myself) am probably more limited by my creativity/capability than camera pixels. Anyone else in the same boat or have experiences to convince me otherwise?
