I got a Nikon D70 a couple weeks ago and one problem i am having is keeping dust and other crap off the lens. I put the lens cap on all the time and stuff like that but it still happens. I also use the lens hood which i would think would probably help keep it from getting stuff on it. I was just wondering if anyone had any hints on preventing it. Ive been able to clean them off with some cleaning pad things my mother had for her old camera, but it would be nice to keep it clean for longer.
