I've got a Canon 50/1.4 and have used the nifty fifty, too.
I find I very much like 50mm, but am thinking I'd like to try some alt 50mm gear.
Any suggestions? I see a Zeiss 50mm 2.0 macro. That's pretty fast (I rarely shoot my 50/1.4 below 2.0 anyway) and I like close-in work.
I see there's also a Zeiss 50/1.4 Planar. Then of course there's the Sigma 50/1.4, but I've never been lucky in the Sigma lottery.
There's also a CV 40/2 pancake.
Any others I should consider?
I'd be interested in interesting bokeh, very smooth mf ring (if the lens isn't supporting AF), and the macro option is nice.
