I don't like anything above 50mm.
I started this thread over two years ago. I can't believe it is still going.
At the moment it's my new CV 40mm Nokton. Only had it a few weeks and despite it's excellent performance I don't think the focal length is suiting me or perhaps it's more the 35mm framelines on my RD1 I'm not used to, as my framing seems off on some shots.
