This sequence was shot with the Thypoch Eureka 50mm f/2 lens on the Fujifilm GFX100SII, using the camera’s native (4:3) aspect ratio (i.e., whole sensor, uncropped).

Although the vignetting improves as we close down, the dark corners do not fully disappear.

I don’t find it to be too troublesome for most photos, as a slight crop (or even correcting the horizon), excludes much of the troublesome bits from the final image.  The rest of the vignetting can be largely corrected during post processing.

In dimly lit scenes, I find the that the vignetting/dark corners enhance the final image.

Considering how small the 50mm Eureka is, it is incredible how well it covers the GFX100SII medium format sensor.  I’m also impressed that its sharpness is maintained throughout the frame and there is only the slightest dip in the edges.
