I think TS already isolate to choices betw. D90, D300 & D300s.
Let's focus on these shall we?
To TS: Personally, I was a D90 user. The decision mindset was simple, D3000 & D5000 (back then) is about the same features as my gf's D60. It was abt 1.4k back then and I could only afford that much. Didn't know much about AF-D lens actually even though I heard about in-built motor in D90. Later I realise the real differences betw. D90 and the entry level bodies and was very pleased about it.... Until I met the big brother D300s.... It's a 2k camera back then. With a price diff of $600, I think common sense will lead you to ask if it's really worth the price. At least to me, it's really worth it. The differences, in features that I was of concerns with, betw. D90 and D300s (or D300) are as follows:
Pros
- Bigger body with better ergonomic grip (Good or not really depends on your palm size
- Wider high dynamic range possibility with wider bracketing range (D90 - 3 shots @ +/- 2 range | D300s - 9 shots @ +/- 4 range) (Do note that this is a personal choice, which I like it)
- Higher Frames Per Shot (4.5 fps versus 7 fps (6 fps for D300)) (a.k.a Multishot speed)
- Mirror up mode (Again a personal preference, I prefer to be able to eliminate camera shake as much as possible)
- Better, more solid built (Rugged with with full magnesium alloy body)
Cons:
- D90 image quality output seems to be, and other also feels, is better than D300s (or D300)
Betw. D300 and D300s, the differences are the ability to shoot video and a tad slower FPS.
All the above are my personal opinion, do take it with a pinch of salt as well. Just like Ken Rockwell, what works for him may not works for me and you.
