Hello! I am looking for a small in size, fast (1.x to 2) 35mm prime for my D800. I have an old manual 24mm f 2.8 that I enjoy shooting and I'd like a fast 35. I find manually focusing longer lenses is a bit trickier but I think a 35mm would still be ok. Anyone know any decent old lenses I might look on ebay or something for? Thanks -rob
