SIRUI 50mm F1.8 1.33x Anamorphic Lens (Super 35 / APS-C)
The lens that made anamorphic affordable: a Super 35 prime with f/1.8, a 1.33x squeeze and Schott glass, now priced far below every other new anamorphic lens. Reviewers found it sharp wide open, with minimal breathing and controlled blue flares.

Caveats
- Covers Super 35 / APS-C only; on full frame you must use APS-C crop mode or you get dark corners.
- Manual focus with no electronic contacts: no autofocus, no lens data in the file.
- 2.8 ft minimum focus; close-up filters work, extension tubes do not.
- 1.33x gives a subtle look: mild oval bokeh, no extreme squeeze. Pick a 1.6x lens if you want more.
- Focus and iris markings are faint and there are no 0.8 mod gears in the box.

Price, availability and each code were checked on the merchant's own US store on the dates shown; they change, so the store's checkout is the source of truth. Full disclosure.
