D300, still worth it?

Hi all

My trusty D50 has finally given up the ghost and so it is time to think about a replacement. I was kinda hoping that the mythical D400 would have been here by now so I could possibly upgrade to that. However, now that I am without a camera I am having to think about what to get in the interim. I shoot mainly landscape, architecture and my very active family.

A while back I considered buying a used D2x. But now I am thinking that perhaps I ought to think about picking up a used D300 instead. One of the reasons for considering a D300 is the fact that I would be using the camera in doors capturing family moments almost on a daily basis. Seems like the D2x may struggle here without flash, and the D300, with its better ISO performance and on board flash might work out a bit better on that front. I hear that the D300 AF is extremely capable, so would be adept at catching the action as it happens.

As regards landscape work, both would seem be rugged enough to cope and take a beating. IQ and DR on the D300 perhaps a little better?

In the end, 12 MP will be a great improvement over the D50, and I’ll have the ability to print bigger. Having greater low light capability is a plus for indoor and family pics. 2013 may see the introduction of the mythical D400, but who knows. In the interim, whilst saving for better glass (currently using Nikon 18-70mm) and keeping my ‘big purchase upgrade’ options open, I need something that will meet my needs over the coming months but also be a joy to use.

Would be very grateful for any feedback from those with experience of the D300.

Many thanks in advance and Happy 2013 to all.
