Fujifilm GF 23mm f/4 R WR Focus Stacking Examples

I’ve published another focus stacking example with the Fujifilm GF 23mm f/4 R WR. This particular image is spectacular in its 3D feel near-to-far. It just comes alive when viewed on a Retina display as on an iMac 5K, and would print very large beautifully.

Fujifilm GF 23mm f/4 Macro R WR Focus Stacking Examples, Eastern Sierra (GFX100)

Images presented at up to 100 megapixels resolution.

For comparison purposes, I include the single frame versus stacked frame for all the stacking examples so far. In this case, the detail rendition of the stacked image is spectacular! The GF 23/4 does not lack for sharpness, but there are some things that need to be understood about how to get that sharpness; I comment on that for this image.

The resolution from the GFX100 finally captures the beautiful wood grain as I have wanted to for years—nothing short of 100MP will do, and now I want 200MP of course!

CLICK TO VIEW: Fujifilm medium format System

I am disappointed that for nearly all gear I’ll be reviewing going forward, the reward-to-effort ratio is much reduced: for the same effort (shooting, then stacking and retouching), my reward versus 100MP on even the highest-res cameras like the 61MP of the Sony A7R IV is an inferior 'deal'. I don’t know if Sony has finally implemented focus stacking support in the A7R IV—seemingly not, a major bummer since its pixel density is equal to the GFX100 and the same demands are there—which downgrades the A7R IV considerably for my favored type of photography.

As usual due to consistently buggy FOCUS BKT feature, I manually shot a far-distance frame, which proved to be critical even for the distant trees on the sunny hillside. I hope Fujifilm gets the bugs worked out of FOCUS BKT soon. It is such a hassle to always have to compensate for algorithmic failures, and this takes time, which can cause other issues, including losing the desired lighting when conditions are changing rapidly.
