I now own a Sony NEX5N, and over the last month have picked up some legacy glass to use with it. Plus the required adapter.
In particular, I got a Rokkor MC PG 50mm 1.4 (love this lens) and also picked up a Rokkor HG 35mm 2.8 and a Rokkor Tele MC 135mm 3.5.
I've only had the glass for a couple of weeks, but the 50mm lives on the camera at the minute.
To be honest, I wasn't real keen on the kit lenses that came with the camera, although to be fair they haven't had much time in use.
Anyone else using Rokkor glass on a digital camera? Quite a cheap but very good alternative to Sony E lenses currently available IMO.
