Fujifilm GFX 100SII

TEST: Thypoch Eureka 50mm + Fujifilm GFX100SII Vignetting @ f/2, f/4 and f/8.

2026, Favourite, Fujifilm GFX 100SII, Print, Q&A, Teaching point, Thypoch Simera 28mm f/1.4, Within 200 feet of My House™

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.

I was trying to achieve a vintage look with this photo, and I believe I was at least partially successful as a result of 3 things:

(1) The way the image was processed (muted colours, less contrast),

(2) The moment caught, in which there are no pedestrians or passing vehicles (pretty rare in a metropolis like Toronto), and

(3) The fact that this stretch of Eglinton hasn’t – yet – been overtaken by towering buildings (the storefronts have more human-friendly proportions that don’t overshadow life on the street and that speak to a by-gone era.
