Regarding your question about using R lenses with the a900, I've only converted my 400 Telyt so far and it works fine. Like everything you have choices. It's a lot easier to adapt R lenses to Canon bodies. On the Sony you have to change the lens mount, not just mount an adapter. But the Canons don't have IS. I'm over 60 so to me IS is a BIG advantage. You're mileage may vary ;-) Jim Laird On Sun, Oct 31, 2010 at 8:15 PM, <afirkin at afirkin.com> wrote: > It would be good to try Doug's DMR trick with the alpha.
