It's time to start a thread that encompasses all of these type of lenses. Though there have been threads in the past that have been devoted to the Isco 3L or Schneider 1.33 lenses, I think now is the time to start a new expanded thread to include all commercially available Cylindrical Anamorphic Lenses. Hopefully this can be a source of reference to all present and future owner's of these lens.
At the present time these are the lenses available and that make up this group.
Cavx MK4, Isco 3s, Isco 3L, Prismasonic HD6000, 1.33X, Schneider 1.33X M, Schneider 1.33X XL. The Isco 3s/Schneider 1.33X M and Isco 3L/Schneider 1.33X XL are identical except for the body. Prismasonic HD-6000.
The current mounts for the Isco lenses are the Tech Ht mounts which include the Cineslide/MultiStand 2 automated lens sled/lens mount system. A Tabletop mount/MultiStand 2 is also available for stationary lens mounting. These work for the Schneider lenses as well. Schneider also has their own lens mount systems available from their dealer network. Currently they have the Kino-Linear slide system, which is being discontinued, and the Kino-Torsion swing system. All of these systems have pitch, yaw and roll adjustments for precise lens alignment. The Cavx Mk4 comes with a stationary mount but should be able to be mounted to a Cineslide or Panamorph sled system.
The advantage of the cylindrical lens is that it works like a traditional camera lens. With the adjustable focus element, you have the ability to have perfect focus from edge to edge, top to bottom, side to side. Artifacts such as Astigmatism and Chromatic Aberration are a non-issue with these type of lenses. Essentially the image enters and leaves untouched with the exception of two things, it's horizontally expanded by 33% and there is a very slight amount of pincushion. Light loss from the lens is small and alleviated by the corresponding gain due to the increased pixel count of 33%.
Unfortunately, these lenses aren't readily available for viewing. Not to many dealers have these or any A-Lens available to demo. Hopefully this will be a place for those contemplating a purchase can go for reference, to ask questions or to be reassured as these lenses are very expensive, though worth every penny, in my opinion.
