I was thinking I might buy a 5n as they look set to drop in price shortly but am wondering if the a57 might be a better buy? Currently about £100 price difference. What would you guys advise? I like the nex form and iq, the phase detection and lens availability of the a57, plus the cheaper price of lenses! Looking at the new e mount 35mm and it's priced here around £400, does that seem expensive? The a mount equivalent is £150 ish.
