Fujifilm GF 23mm f/4 R WR Aperture Series: Dark Rocks and Flowing Water, Upstream View (Fujifilm GFX)

See my Fujifilm GFX wish list.

Anyone shooting medium format is presumably seeking top quality and thus ought to be thinking in terms of focus stacking, at least for near-far scenes like this. That’s because depth of field is in short supply. Stopping down too far degrades brilliance and depth of field too often remains inadequate even at f/16—an image dulled from diffraction that is still not fully sharp near to far.

Accordingly, this series incorporates a two-frame focus stack at f/10 which provides an intriguing look at what is possible versus f/9 and f/13 by optimizing focus for the two-frame stack.

Includes images up to full resolution from f/4 - f/13 as well as the 2-frame focus stack at f/10.

I really like Fujifilm’s variety of camera profiles for the Fujifilm GFX; they make it easy to get an image that looks more film-like than many a camera. This one used PROVIA/STANDARD, albeit with a reduction in contrast and other parameters—ACR settings shown as I usually do.

I have no hesitation in giving my highest recommendation to the about $2600 Fujifilm GF 23mm f/4—this is the lens that anchors the system in my view.
