The 21/4.5 C-Biogon is not available yet, I recall the release date will be in spring 2007. No price known so far, but I'm shure it will below the 2.8/21mm. The C-Biogon will certainly be a good performer as it can be expected from Zeiss, but it's useless to predict how it would compare with the other ZM 21mm.
The main rival on the market, in terms of performance, price and compactness, will be more likely the 21mm Color Skopar, not the other Biogon.
Luigi case ("rally") with a R-D1s in it, a dust-catching M6, some german and japanese glass. And some evil stuff, too
