I use Nikon camera equipment, so what I am about to say may not make Nikon extremely happy. Only you know what camera will be best for you to use. I always tell people to go to a camera store or the camera department of a store you like to shop at. Pick up the various cameras and look through them. Test the ease at which you can change the settings. Look carefully at the menu and see if it makes sense to you. The camera that best meets all the criteria of comfort, features, and quality that you demand of it is the camera you should buy. The camera manufacturers would like you to think that their cameras and lenses are superior to their competition, and sometimes they are, but if you do not find the camera comfortable to use, you are not going to recommend it to anyone else. That said, I bought my Nikon’s because they have always met my needs.
The big 3 camera makers, Nikon, Canon and Pentax, each make high quality camera’s. Nikon is rugged and has top notch glass. Canon is a bit more varied than Nikon and also has great glass. Pentax is a bit more innovative and rugged, and their glass is quite good, with cost becoming more important in my selection, if I were starting out today, I would seriously consider Pentax.
My choice of Nikon was made long ago when I started shooting film. The controls of my camera are intuitive to me. I know where to find the commands I use most often on my cameras. The transition from film to digital was not difficult because Nikon kept most of them in the same location I had gotten used to using. Their menu for the features that I wanted to learn made them easy to find. I suspect Canon and Pentax did things in a similar manner.
So when selecting a camera, choose the one you find most comfortable when it is set up with a lens that you prefer. That is the only way you will be happy shooting.
