Just ordered a lens I've been web-window shopping for, for some time, the Sigma 20mm f/1.8. Looking forward to using it on my DSLR and when I get my LEX later this month I'll be sure to post some footage with it. Wheee!
i have sigma 20mm 1.8 and been using it with my lex... i have to say i'm not happy with it.. it's bright, but at 1.8 LOTS of CA, no focus in the corners, unless you step down to f5.6 or more, but you can't cause you see noise from vibrating glass... i'm thinking to try something else, like nikon 20mm 2.8.
Hmm, damn, I'd heard good things about it from Phil Bloom, and read some pretty positive reviews. Well, I guess I'll just have to see for myself when it arrives.
