Also Pentax…
Sony know they are the Apple of cameras - you will buy into Sony gear and add ons (like flash systems, etc, which for macro you may get into!) only, for the mostpart, where as the other three (Nikon, Canon, Pentax) you can typically use 3rd party stuff.
A lot of folk like this one, especially since you dont want to get technical, while it wont do telephoto stuff you want (things at a distance) it will do the rest pretty decently.
