Hi everyone. I am a former Canon dslr user. I sold my old canon 40D and lenses a while back and am getting the itch to get back in the dslr hobby. I have done tons of research and narrowed my choice down to the Nikon D3300. How is the sensor on this camera? Is it hard to keep clean? Are there any new cleaning supplies for dslr lenses? That was probably my biggest pain in owning a dslr. I currently own 2 high end Canon compacts. I wll probably get the 18-55kit lens. What other lenses would be appropriate for this camera. My main shooting will be landscapes and portraits/candid portraits. Not really into sports. Would the 18-55 pretty much be all I need?
