I have an Anamorphic projection lens that was created by Iscorama for Runco Reinier. It originally sold for between $6000-$8000. It has higher quality glass than the Iscorama 54's which it resembles and are popular right now. It is stated as a 1.3x, but I have actually found it to be 1.5x. I worked with a German optics professor who is well known here (Dr. Klaus Schmitt) to build a structure around it and have extra diopters for close up work which are very rare for it's size (92.5mm). There are two tiny microscratches on it's back element and perhaps a few specks of dust which were there from origin before we purchased. As it is an amorphic lens (used to eliminate distortion in abnormally wide throws) so they are therefore inconsequential, and this was re-confirmed by Iscorama Gottingen themselves before we decided to go ahead and take it.
We built the rear threads with a 77mm diameter, the rotating locking pin unit to change / level out the anamorphic plane, and the the front threaded holder for the diopters. (92.5mm). The diopters for work in the closer 2 meter range are VERY RARE and one would have difficulty finding them in this size normally. I believe there are only 2 or 3 sets left in the world.
Edit: A new rear mount was machined to approach the taking lens by almost a full centimeter for additional coverage. A duclos delrin gear ring has also been added to the barrel.
Additionally there is a small chip on the .5 diopter near the edge, which is also of origin before us and does not affect image quality because of it's peripheral nature.
Further edit:
Because so many people have asked how this lens compares to the Isco 54 and more details about the lens, here goes:
The rear adapter I had made twice. The second one currently on the back of the lens is closer than the previous and of higher quality. It has a 77mm thread for taking lenses, which you can use step down adapters on quite easily. This allows for a much greater variety of lenses like the 54. I have also invested in a Duclos ring for the anamorphic focus ring.
Like the other Iscorama's I have found focus can be achieved using only one lens. However I have also found that unlike all the other Isco's it functions in the opposite way! Generally, I have found that once I set a good intermediary mark for the anamorphic I can pull focus with the taking lens rather than anamorphic. This is rather unique.
Closest focus without diopters is around approximately 170 cm (the 54 is around 200cm)
For the diopter 2.5x closest focus distance is approximately 110cm.
For the diopter 1-2.5x it is approximately 85cm.
For the diopter 0.5x it is approximately 35cm.
lens length - 10.5cm
lens diameter - 9.5cm
rear element glass size - 62mm
I don't know exactly how much the lens weighs, I would say slightly more than a kg.
The corner sharpness is excellent. It is an amorphic lens, which means it has been designed to eliminate distortion in abnormally wide throws. You will therefire find less curvature at the coners and sides than a typical anamorphic.
All three elements are hand machined parts you see in the third photo of the ebay listing, and the beveled retaining plate + adapter were expensive to make. They are designed to be as close to the rear element as possible. I invested somewhere around £1000 for the diopters, duclos ring and the hand machining of the parts. (Yes, the latter can be very expensive for one-off's, especially the beveled piece).
If you need additional information about the lens itself I would suggest you contact Isco-Gottingen directly.
