Fujifilm GF 45mm f/2.8 R WR

TEST: Thypoch Eureka 50mm f/2 and Fujifilm GF 45mm f/2.8 @ f/2.8.

2026, Favourite, Fujifilm GF 45mm f/2.8 R WR, Fujifilm GFX 100SII, Inspiration, Print, Q&A, Teaching point, Thypoch Eureka 50mm f/2, Within 200 feet of My House™

We’re testing for central sharpness, with both lenses at f/2.8, on a Fujifilm GFX100SII.

For the GF 45mm, this represents wide open performance.  The Thypoch 50mm is slightly stopped down, which gives it an advantage.

Looking at the images, the GF 45mm wins.  However, the result is much closer than I expected, even though I already knew the Thypoch performance is impressive.

With the Fuji lens, you also get autofocus, weather sealing, and less vignetting.  With the Thypoch, you get a maximum f/2 aperture (not shown here), and a much, much smaller and lighter lens.

For me, both lenses are keepers.

I met Marwaan while I was photographing this corner of the street, which was lit up by some lovely late afternoon sunlight.  He asked me if he ruined the shot when he entered the scene and I told him no, but then quickly asked him if he wanted his portrait done.  Marwaan graciously said yes and the result is what you see here.

While chatting, I learned Marwaan had had a great day at work and was on his way home when our paths collided.  Thanks Marwaan, for making my day a little brighter too, by agreeing to have your photo taken.
