With my Fujifilm GFX100S arriving tomorrow, and the Fujifilm GF 35-70mm f/4.5-5.6 soon, I took a look at its distortion characteristis using some sample files I found. My concern was how much distortion at what focal lengths, and how much is lost by correcting it. This prompted me to document a very low distortion lens, the Fujifilm GF 50mm f/3.5.
I had assumed that the low level of barrel distortion with the Fujifilm GF 50mm f/3.5 meant that distortion correction had minimal impact. That assumption proved incorrect.
These examples show distortion-corrected vs uncorrected images for the Fujifilm GF 50mm f/3.5 R LM WR:
