After about a month of using the sony a57 i returned it and purchased the canon t4i. So far, so good. the sony took great pictures, it just did not feel right in my hand. I also thought about betamax every time i looked at it. hard to drop close to a thousand dollars and have that feeling all the time. Hope i made a good choice. Wish me luck.
I'm not seeing the connection to the Sony Betamax or how that is relevant to the Sony camera taking "great pictures." The resulting "great pictures" is all that should matter in the end and Sony certainly makes nice cameras and is one of the leading sensor makers.
