I had mixed feelings about the 21mm ZF so I went out for a couple of hours to see If I could give it some more loving. It is a sweet lens, makes me wonder why you would ever want AF, what I don't like about it is the lens cap. I am yet to grab a UV filter for it & trying to put the lens cap on while the hood is attached is difficult with bigger fingers.
The Voigtlander 125 is an awesome lens, but the prices have gotten beyond ridiculous.
I'm looking forward to seeing what how the new Zeiss 135 performs...any word on when that one is released? I'm guessing Spring 2013.
