Fujifilm GFX 50s + 120mm f/4 Macro Plus Diffraction and Sharpening Evaluations
See my Fujifilm GFX wish list.
Kicking off my evaluation of the Fujifilm GFX in the Medium Format section, I start by evaluating the lens performance of the about $2699 Fujifilm GF 120mm f/4 Macro R LM OIS WR:
Fujifilm GFX 50s + 120mm f/4 Macro Aperture Series @ 1:10: Dolls
Includes images from f/4 to f/16 at up to full resolution along with large crops.
The findings above have a serious 'gotcha', and y’all are not going to like what I have to show for distance performance with the 120/4.
Adobe Camera Raw support for the GFX just arrived today. What I have found is that the GFX does not behave at all like the Hasselblad X1D in terms of sharpening or diffraction.
Accordingly, I take a detailed look at mitigating diffraction effects as well as how much to sharpen GFX files in Adobe Camera Raw. I think these two pages should be very helpful to any GFX shooter:
Fujifilm GFX 50s: Mitigating Diffraction from f/4 through f/32
