Hiro, this is not a bad buy. I have the same lens, here is the test footage i have made yesterday. https://youtu.be/ZAqUDLmO_zM (EOS 50D, RAW recording) decoded in MLV app, Exported to Prores 422. (presented in 720p in youtube.)

Anamorphic lenses, especially the projection ones, suffers from some sharpness loss. This is mostly noticeable on wide f- stops under f8 and depending on what the recording format / bitrate used. -I have had most success with dialing the taking lens to f16 - f22 to increase sharpness to maximum, understandably this needs lot of light or ISO, depending on the situtaton in hand. Also recording the footage as RAW (magic lantern etc.) and post prosessing the RAW /MLV files in post will contribute to overall sharpness conceivable using the cheaper anamorphics. In the past weeks, I have been testing various workflows and you can see the "best" results here, using vintage EOS 50D, with RAW recording. the footage was edited in the free version of Lightworks, so it´s only presented as 720p in youtube. But please take a look, anamorphic lens used is ISCO 2x (the big golden one.) https://youtu.be/ZAqUDLmO_zM

I have the same lens. As this has model has been made for projection, it has a coating to prevent flare. You can buy the adapter which are not cheap, but you can also unscrew the rear threading ring, and replace it with step down ring to connect it straight to your camera lens. Basic 50mm DSLR lens will wignet a lot with this lens so use 50 mm lens from analog camera. Beware plastic adapters and use a sturdy DSLR rig.
