Hi, I'm brand spanking new to this forum and I'd like some advice. I dabbled in photography during high school - pre-digital age- and now I'm rekindling my interest. I've been researching some cameras and I'm deciding between a Sony a37 and a Nikon d3200. Both good cameras. I like that Sony's offers 7 frames per second, but I like Nikon's 24 megapixels. I don't want a camera that is too overwhelming, but am looking for something that will grow with me. Thoughts?
