Hi, Marek. Sorry, it’s easy to be confused when you don’t have the products in your hands. Firstly you are concerned about the outside diameter of the lens housing. That’s not really relevant.
Let’s consider the physical specs of the 1.33x-65mm Anamorphot adapter.
This adapter is optically designed for taking lenses with 30mm and longer focal lengths. For example the SLR Magic 85, 50, and 32mm APO. It won’t work well on the 25mm APO but I think one day I’ll try it anyway, just not yet.
The 65mm refers to the maximum diameter of the entrance pupil (the visible diameter or the front element) of the lens. If you have larger front elements, the Anamorphot won’t work properly. Smaller front elements will work.
The adapter has a 82mm thread designed to screw-on a lens (or step-up ring) with an 82mm front thread. All new APO lenses have 82mm front threads. I use a 62-82mm Heliopan brass step-up ring on my original generation 50mm APO prime.
This adapter is quite large with an outside diameter compatible with 114mm matte boxes. It’s also heavy so I strongly recommend the beautiful SLR Magic Lens Support for this lens as it integrates very securely with the adapter. The adapter ensures your squeeze is perfectly vertical.
It’s a lovely setup for the URSA Mini 4.6K PL to transform 16:9 into widescreen layouts that unfortunately I cannot use with the even larger short focal length Tokina Cinema ATX 11-20mm T2.9 PL zoom. But it’s a perfect squeeze adapter for the BMPCC4K with the Fujinon MK mFT zooms that I hope to acquire as budget allows, first the 18-55mm please (squeezed in the 30-55mm and 50-135mm ranges).
