That is what the Zeiss data sheet for it implies, however they also mention floating elements:

While looking at the line drawing of the lens, it struck me that its profile is almost identical to the mystery lens at the right side here: http://blogs.zeiss.com/photo/en/?p=5340 that we were speculating to be a 35/1.4.... What I thought was a rear element protrusion might actually be the mount itself if one ignores what looks to be a lens mount flange just above that part... I don\'t know.... Back a couple years ago apparently Zeiss was going to make another batch of the 85/2 but decided not to... it\'s one lens that should be mirrorless compatible as is. They could drop the cam from it and reintroduce it at a lower price. Though it wouldn\'t really make sense to do that and not have it fit in with the Loxia lens design.
Andrew, do you still have your ZM85/2 and how does it perform on the a7R?
Hi Ron,
I still have the ZM85mm, but only an A7s. Do you have an an A7r?
Andrew
Hi Andrew, I don\'t have any of the Sony cameras, but could probably get hold of an a7R.
Edward - thanks for those samples. It looks great, In fact I think I prefer its rendering over the 90AA...
You\'re welcome Ron! The Sonnar has a problem with blue fringing in highlights wide open. I believe the 90AA is very well corrected for that. Apart from fringing, indeed the Sonnar rendering is fantastic.
Hmm I think the 85 2 zm is actually a double gauss/planar design:
I thought that as well - and made reference to it earlier (\"Zeiss can call a Sonnar/ Biogon whatever they like, regardless of the actual design\") but theSuede said there is actually a formulae that Zeiss go by per named design that not neccesarily has to do with the number (and I presume position) of those elements.
