I have the Nikon D50 for the last 3 years now and have been very happy with it. However I am thinking about upgrading towards the end of the year (when finances will permit) so I am looking for some advice and opinions from people. I want to stick with Nikon as I have a couple of lenses and flash so I don’t want to have to change all my kit and I am happy with Nikon. The extra functions I am interested in are auto bracketing and multiple exposures. What Nikon would people recommend and what sort of price are we looking at.
