I'm inheriting a few good minolta lenses (35-70mm, 50mm, 80-200mm) and a Minolta 7000 Maxxum. I'm a huge fan with the ease of use of digital, and have been looking at the Sony Alpha. From what I've read, the 7000 Maxxum uses the A-type mount, as well as the Sony. So my Minolta lenses should at least fit on the Sony, but will they auto focus with the Sony, and will the Minolta lenses focus near infinity? I also understand there is the 1.6 crop factor, so I'm going to need to purchase a good wide zoom lens (mostly because I want to shoot skateboarders). I just don't know exactly what to look for. I want a lens that will blur the background nicely for close up shots, but will that kind of lens be capable of nice sharp landscapes as well? I'm currently looking at the Sigma 10mm - 20mm f/4-5.6 EX DC but it seems a little "slow" when compared to the Sigma 18mm - 50mm f/2.8 EX DC Macro. Both are right around my price range. Thanks, Tyler.
