Hi everyone! I've been a Canon shooter for quite a while but have fallen in love with my new NEX 3n because of its size and IQ. I bought the kit with the 16-50 and 55-210. I have the following Canon lenses: 80 1.8, 70-200f4L, Tamron 28-75 2.8, Sigma 50mm 1.4 and Tamron 17-35. Basically I like this setup with my FF 5D but I would like to get APS-C lenses such as the Sigma 10-20, 30 1.4 etc (which I could also use on my 30D). Would I be better off getting the Sony adapter and buying these third party brands in Sony mount, or would I get acceptable AF performance with Canon mount and the metabones adapter? I'm a big fan of third party brands because they are great value. I will be selling some of the Canon lenses which are either expensive or I don't use often. I might just keep the primes to use with the 5D if I decide to go the Sony route.
