I am selling a new Mosler 35mm F2.8 for Exakta mount. This is a preset lens, although it might be fundamentally a T mount lens as it may have a T ring on the back, but I have not tried removing that to verify (there are some small set screws). If it is a T mount lens, it will also work on virtually any camera made with the appropriate T adapter, which can be handy! I bought this lens new about six years to try out on my Exakta, but never got around to it.
The condition is new, except I have noticed what night be a faint trace of oil on the aperture blades, which is inconsequential as this is a preset lens (and the iris moves freely). Sometimes a slight friction in the focus action can be noticed, but this is also not at the problem level for use (IMO). The glass condition appears to be perfect.
This is a compact and nice looking lens, and fairly fast for what it is. I'm sure it will deliver some useful images and make a nice addition to any retro collection.
