Marc Alhadeff from SonyAlpha.Blog tested the new Sirui 75mm f/1.8 Anamorphic lens and concludes:
The Sirui 75mm F1.8 Anamorphic is a nice addition to the existing Sirui 24mm F2.8 Anamorphic, Sirui 35mm F1.8 Anamorphic, Sirui 50mm F1.8 Anamorphic to cover most situations.
This one is more focused on portrait and achieves its target with globally a nice rendering for portrait but inferior to a standard portrait lens .
- Sharpness is OK wide open but you gain a lot by closing by one stop.
- Color rendering is a good but not very neutral.
- Background blur is good and soft in general but can quickly become nervous
- Bokeh balls are quite small as min focusing distance is big : 1.2m
So very good for an anamorphic lens, average if you compare it to a standard portrait lens
