So yesterday, I received an unexpected gift from a distant relative... a mint Konica Minolta 7D with two lenses - Tokina 28-80/2.8 and Sigma 12-24/4.5-5.6. Before that, I was kinda/sorta toying with an idea of getting an adapter and some old Maxxum glass for my Nex, but the size of the lenses put me off.. now that I have a couple lenses and the camera body to put them on (granted only 6.1MP but still should be good for most type of shots) this becomes almost a must. So, I have two questions. First, what AF lenses from film Minoltas are really good ? As I understand, the MD glass can not be used on A bodies, at least not with infinity focusing. I plan on using Nex as my main camera, still, so getting a Beercan, 50/1.7 and 35-70/4 Macro in AF versions is probably not going to happen unless I find them for a ridiculously low price - I already have them in MD. I need glass that I could use both on the Konica 7D and on Nex. Based on a quick web research, the Tokina is basically an OK lens, wide open, not as sharp as say Sigma 17-50/2.8. But Sigma 12-24 seems to be getting pretty good reviews. This covers the wide range - and that's what I am missing, my widest lenses for Nex are the 18-55 kit and Sigma 19. I don't yet want to invest in expensive more modern Sony Alpha glass, as I am not sure where I would progress from here, and don't want to drop over half a grand on a lens I may end up not using much. 2nd, do I understand it right that LA-EA2 adaptor has it's own PDAF and so would provide fast AF even on the Nex bodies that only have CDAF, like F3 ? I don't mind paying extra $100 to get fast focusing, but I am a bit put off by size difference vs LA-EA1.
