I know this thread is old, but the board won't let me make a new thread to ask about all the 20/21mm options at once, so I'm kind of stuck using these old, dead threads!
Just wondering if anybody can give any input as to whether this Zeiss is still worthwhile today now that lenses like the Sigma 20mm f/1.4 and Samyang 20mm f/1.8 are out, where the Sigma has AF and the Samyang is a bit lighter (and cheaper!). It's easy to find example photos but that doesn't tell you much about how the lens is to really live with. And most examples I find are of landscape or astro, while I'm looking at these lenses for indoor use when 24mm is proving a little cramped.
