Is the 7artisans 25mm f 0 95 sharp wide open?

I don't have sharpness test results for the 7Artisans 25mm f/0.95, so I can't honestly say how it performs at f/0.9. What I can tell you is that it's a manual-focus prime, so getting a precise focus at its widest setting depends on your technique and on a focus-assist tool like magnification or focus peaking. Its depth of field is very thin wide open. On APS-C it gives about the depth of field of f/1.4, so your focus point needs to be exact. The 7Artisans 25mm f/0.95 page has the full specs and the list of cameras it fits. For how wide apertures affect sharpness on a subject, see Portraits.
