It looks like the Samyang site is offline, possibly due to a spike in traffic on this the official announcement day of the new 135mm f/2.0 photo lens and 135mm T/2.2 Cine Lens. Initial comparisons show an improvement in areas of chromatic aberration as well as sharpness at f/2.0 compared to the Canon EF 135mm f/2L USM Lens.

I've taken the spec table from Samyang and remade it with Millimeters and Grams converted to Inches and Pounds. Looks like the lens will be released for  10 different mounts as I suspected.
