Also Zeiss promised at least one fast ZM lens in 2013!

Sonnar I guess because allow more space between sensor and last lens element.
55/1.4 Distagon probably using a medium formula for 35mm, where 55 in medium format is wide angle. Otherwise the lens would not be so huge with a 82mm filter thread!
The previous widest Sonnar is 50/1.5 on RF and the longest Distagon is 45mm on M645. So having a Sonnar 35/2 and Distagon 55/1.4 is interesting.
The previous widest Sonnar is 40/2.8 on Rollei 35. Longest medium format distagon I think is 80/2.8 on Rollei sl66.
Well, these "Sonnars" aren't real Sonnar designs, and neither will this be. The Sony/CZ Sonnar 135/1.8 and 24/2, for example, have nothing to do with the classic Sonnar design, and this has been so for quite a long time. For example, the Contax G 90/2.8 was marketed as a "Sonnar" but is really a very classic Ernostar (cemented doublet at rear). So the "Sonnar" designation basically nowadays seems to mean "fast, expensive quality lens". Of course one can argue about what is a "classic Sonnar", and if it is desirable when coatings are better and exotic glass and aspherics have made completely new designs possible.
On a somewhat tangential, but topical, note I have succeeded in putting a 5/4 "Sonnar" on my NEX-5:
Magnus Wedberg, photography and design. Contax T stripped down for NEX
Alas, no cemented triplets there, either.![]()
My bad. I am not familiar with Rollei and didn't realised they are so forward thinking.
This is an awesome mod. You must have spent lots of time designing, fabricating and calibrating the lens.

If not you can go Sony..with AF Zeiss lenses.I am thinking of moving to a FF DSLR and playing with Zeiss lenses.
Anyone can share any experience regarding ease of MF with Nikon (eg. D600/D800) and Canon (eg. 6D/5D3).
