Hi there, I am in the process of upgrading from my Nikon D50 and after some research I have 99% decided on the D200 as I can afford it if I buy a 2nd hand body and it fits into my requirements as in Faster AF, faster shutter reponse, better field of view and additional functionality. However before I part with my hard earned cash I was hoping to get some opinions from people here who have one. Do they recommend as an upgrade, what sort of problems they have encountered that I should be aware of and also what number of shutter actuations I can expect from it so as to know what to look for in 2nd hand models. I am not particularly technically minded so please keep the jargon to a minimum (or at least accompany it with an easy to follow explanation Thanks in advance everyone. Mark S., Dublin.
