What kind of composition requires corner to corner sharpness with a large wide open aperture (1.4 etc)? I'm genuinely curious.

none. nothing in any of the corners will be in the focal plane unless you're shooting a fucking wall.

I need it for shooting brick walls and test charts, which make up most of my photography

Hyperfocal ultra wide angle landscapes. That's pretty much it.

Unless you have a specific use case, a slight edge blur and vignette will help guide the viewer's eyes towards the subject

>Astro starfields
best actual answer
also >>4125056
also when you happen to want to focus on something near the edge of the frame, though that's not strictly corner to corner

There's plenty of crop and cine lenses with superb corner performance wide open. High end olympuses and leicas...

corner to corner sharpness wide open isn't really a thing outside of something that youtubers who make money talking about lenses say. it's stupid.

Have you ever seen a DOF scale in your life? Especially on a wide angle lens?
