Fujifilm GF 45mm f/2.8 R WR Aperture Series with Focus Stack: Indian Rock
See my Fujifilm medium format wish list and get Fujifilm GF 45mm f/2.8 R WR at B&H Photo.
B&H Photo graciously loaned me the Fujifilm GFX for the 4th time this year so that I could review the 45mm f/2.8. Please support B&H generosity by buying your gear through links on this site, such as the wishlists.
The about $1699 Fujifilm GF 45mm f/2.8 R WR for Fujifilm GFX is now shipping. And even though it is a brand-new release, it is still $300 off as I write this.

This aperture series look at moderate distance (a few meters) performance from f/2.8 through f/11 along with a 4-frame focus stack at f/11. It shows off the Fujifilm GF 45mm f/2.8 at its very best—a very impressive performance.
Aperture Series With Focus Stack: Indian Rock
If you’ve held off on focus stacking, but are interested in cameras like the Fujifilm GFX or the Hasselblad X1D or Nikon D850 or Sony A7R III—you had better get started with focus stacking yesterday, as I think the stacked image in this series makes obvious, as with the other series. See Getting Started with Focus Stacking.
Includes images up to full camera resolution from f/2.8 through f/11 plus the 4-frame focus stack at f/11.
Below, I am almost shocked that in this day and age some loser has not defaced this work of art. Let it remain so!
