    Way up there.
    I was looking into gettng a focal reducer for either the canon ef or nikon f mount. My question is, i have some m42 lenses i would like to use and is there an adapter for one of these mounts that will focus to infinity? I would like to know because if i can't get infinity focus, i may just buy a cheap m42 focal reducer. Anyways thanks in advance. I think it might just be better to get the nikon one as i have nikon legacy glass because then i will need an ef to nikon adapter and i am not sure if that would focus to infinity.
