Is the 7artisans 25mm f 1 8 sharp wide open?

I don't have sharpness test results for the 7Artisans 25mm f/1.8, so I can't tell you how it performs wide open. I'd rather not guess.

What the page does cover: it's a manual-focus prime for APS-C, and it's listed for Sony E, Fujifilm X, Nikon Z and Micro Four Thirds. On APS-C it frames like about 38mm on full frame, and at f/1.8 it gives the depth of field of about f/2.7.

For what f/1.8 means in practice, like blur and how much light it lets in, the aperture section of the lenses guide explains it. If you want to see how a wide lens handles a subject, the portraits guide is a good place to start.
