Been playing the which DSLR should I get game. So far I like the nikon D5100. canon T3i, and the Sony A33/A55...I have been able to handle them all and none really stood out above the rest IMO. Anyway, the more I read etc, I am starting to lean towards the A33/A55. I like the the features & tech that the camera has and was wondering a few things... Is there that much of a difference between the A33 and A55 to warrant the extra $150? I know A55 has more MP and the GPS which aren't huge factor for me, what else though... And I read that Minolta lenses work with the A33/A55. Is it all or just a select few? What are some good wesbites that sell the Minolta lenses? Thanks!
