In search of a better lens for my maxxum and Alpha, i was going to look into the Sigma 24-70mm f/2.8 from Kits because the company was having a big sale on a good portion of Minolta mount lenses. I had heard a rumor of a problem that a large batch of those lenses were having issues where they will not work, not even in manual focus mode. I ordered it, and when i tried it out, did not work at all with my maxxum or Alpha. So i returned it and was gonna pick up the Sigma 105mm macro instead, but even after 2 months, they still haven't gotten it in. Has anyone else encounter a similar problem? If it's sounds like what i've heard, i'll go back over and pick it back up and send it out to Sigma to get fixed. Thanks guys!
