Selling a used Century Optics 1.33x ratio anamorphic lens. Cosmetically it's in excellent condition. No scratches, or fungus or dings, besides where the screws are. Rear thread is 37mm. Comes with 37mm - 52mm rear adapter and front screw-on lens cap. No need for clamps.
Best used on a cropped sensor camera APS-C or micro 4/3 or miniDV. Full frame would work too but give you vignetting on wide angle lenses.
This adapter is similar to the Panasonic LA72000. No focusing is necessary.
I just bought this lens on ebay the beginning of December. I've barely owned it. In my opinion, with my lenses and my camera the image quality did not hold up enough to justify keeping it. Shows chromatic aberrations, not sharp at wide open apertures, but fits nicely.
