I'm looking for suggestions for inexpensive dedicated macro prime lenses. Adapted seems like a solid option for this sort of thing (especially since you're using MF for most macro work anyways!). Ideally, I'd like something that would double as a usable fast telephoto prime, so something in the 90-110mm ~f/2.8-4 category (faster is always nice). 1:1 magnification would be good. If possible, I'd like to spend <$150 for a decent copy. Weight/size aren't super important to me, since this wouldn't be an every day carry sort of item. I've heard good things about the Vivitar Series 1 105mm f/2.5, and it fits my criteria to a T, but it seems a little pricey for a copy in good shape. The Vivitar 90mm f/2.8 is a bit cheaper, but I don't know much about it. What are some alternatives that offer a good balance of price, speed, macro performance, and infinity performance in this focal length range? Any opinions on the two lenses I've noted? Thanks for any help!
