I had a SD14 with the 18-50mm f2.8 and I found that K mount lenses could be fitted to the Sigma body, but they are slightly loose (I secured my modified 50mm with bluetack!), and Sigma mount lenses...

I've owned an Nex 5n and I now own an a37... I think that the mirror definately reduces detail (marginally) and also increases noise by a 3rd of a stop as you need more exposure to get the same...
