Yes - well, the 35L and Contax 35 f1.4 even have very similar looking length, girth, and size/curavature of front and rear elements, which is why I use the word suspicious.
No need to speculate... here are block diagrams:
The Canon is an 11/9 design and the Zeiss is a 9/8 design. Both have a single aspherical surface. The length and girth similarity is due to the fact that the lens is very fast and it takes some space to fit enough elements to make such a lens sharp. Other than the fact that they're both reverse-telephoto lenses (like pretty much all SLR wide-angle lenses) they seem pretty different.
The newer 35/2 is a 9/7 design and again pretty different from both f/1.4 lenses.
Anyway, all three are amazing. I'm glad we have so many options at this focal length since it's one of my favorites. Between these three and the flektogon and EF 35/2 anyone could find the lens for their needs (AF, close focusing, bokeh, "look", weight, etc.)
Edit: I just noticed the 35/2 is only 50g lighter than the 35L. Ouch.
