Hi guys, my name is Tom I'm pretty confused. I'm looking to buy a nikon d3000 but I cant figure out for the life of me if my slr lenses will fit on it. I've searched up and down and I'm starting to get pretty frustrated. I was hoping maybe someone could help me out. The lenses I'm looking to use on the nikon are a Vivitar 70-150mm 2x matched multiplier, a Vivitar series 1 macro focusing 28-90mm lens, and a olympus zuiko auto t 200mm lens. Any help would be greatly appreciated. This place looks really great, thanks in advance for any help that is given!
