The Nikon D300 is the camera that I use most of the time and I really love it. It is strong and robust, so you don’t have to worry too much. It responds very quickly – certainly fast enough for my needs. The controls are very easy to master and there are lots of books, web sites and forums to help you share information with others and ask a question if you need to.
The battery life is fine but I did have a problem in the early days when I arrived at something special and found the battery flat and I had no spare. So I bought the Nikon MB-D10 battery pack and haven’t looked back. I set it to use the pack first and it is really easy to remove the battery for charging. If you leave it too late, you know you have the one in the camera as back-up.
Perhaps the major benefit though is that it has a shutter release and joy stick control for shooting in portrait mode and it also give the camera a much more satisfying profile that sits in the hand better. The only draw backs for me are that it makes it quite heavy and also more difficult to get into a compact bag for the times when you don’t want to take the whole kit and caboodle with you. However, if you really want to travel light, it is simplicity itself to remove – just make sure the battery in the camera is fully charged!
