Is the laowa argus 33mm f 0 95 cf apo sharp wide open?
I haven't tested this lens's sharpness wide open, and the site doesn't have that kind of test data for it, so I can't tell you how it performs at f/0.9.
What I can tell you is what the Laowa Argus 33mm f/0.95 CF APO page covers. It's a manual-focus prime for APS-C cameras, with no stabilisation. On Sony E, Fujifilm X and Nikon Z APS-C bodies it frames like a 50mm on full frame, and wide open its depth of field is about that of f/1.4 there.
Because it's manual focus and very shallow at f/0.9, you'll want to be precise with focus, and a camera with focus peaking or magnification will help. For more on what a wide aperture does to a subject, see portraits.
