Hey guys, that's my first post here. I've been reading this forum quietly for quite a while and finally decided to reveal myself, since I need your help as I failed on my search for a good copy of this lens. I've got one on my right now but due to issues with it, it will have to go back to seller - focus ring sticks at infinity and aperture ring is quite loose. Anyway, I struggle to find this lens in reasonable price. I think that I went through whole internet in search for one in decent price but I failed - and it's been going like that for three weeks now, I never experienced something like this with any other piece of equipment. Could you please help me out? I'm based in UK, so whole Europe is fine. Thanks!
