The 12mm was actually replaced by another camera system - I converted to micro 4/3, so now I'm using Panasonic 12mm lenses for my wide angle shots.
I never had the 35mm 1.8 as I went straight to the Sigma 30mm 2.8, but I had an older version of the Sigma 30mm 1.4 on a Nikon DSLR. As far as I remember it was a great lens.

How do you like the micro 4\3 compare to APS-C, and what was the reason for you jumping ship?
Thank you kindly. That was zone focused too. No viewfinder used for it.
I was checking your Flicker page, really digging your pics, spacial the low light\night stuff!
