(First post here; been lurking a while. Thanks for having such an awesome, informative forum.) Last week I came into possession of a NEX-5R (sold to me, indeed, by a member of this forum). After several years of point-and-shoots (and before that shooting film on an old EOS), I decided I wanted something small, but with more control and better quality than what I could achieve with a compact. I picked up the 16mm pancake, and the Sigma 30mm (which I've been using primarily), and I was initially planning to get the Sony 50mm, to use for candid/casual portraits. However, through reading this forum I've become very intrigued by the idea of purchasing one of the many legacy 50mm lenses instead. It seems there are some good ones available below £100, and I was thinking I could use the extra money I would have spent on the E-Mount 50mm, to purchase the EVF attachment (which I gather is something of a necessity for manual focusing?). I feel embarassed to say, that I've rarely actually focused manually before. How hard is it on NEX? I'm not interested wildlife or sports photography, but I'll be taking pictures of children, and worry I wouldn't be able to find focus fast enough. I've tried focus peaking on the Sigma 30mm, and found it fairly easy to get sharp pictures, but I imagine a longer focal length and wider aperture makes it a lot harder. If I do go for a manual lens, what are the best ones in the 50 - 60mm range for those on a budget?
