I’m getting what looks like barrel distortion whenever I scan 6X7 120 negatives.
I’m using an A7iii with a Nikon 28-105mm f/3.5-4.5D Macro lens with an adaptor, set to about 80mm, converting with NLP.
The negative’s frame fills the Sony’s frame nearly to the edges.
I’m using the Lomography Digitiliza to keep the film flat, and placing it on top of the Skier copy box ii having removed the skier’s metal film holder.
(I removed the skier’s metal film holder, as I’ve found when trying to run 6X7 frames through it they nearly always get caught in the metal when trying to slide them through or slide off the groove. Even if I (rarely) succeed sliding them through, they’re not flat.)
I suspect the distortion is is from the lens, and if were to get a better and native lens it might fix the issue, but was hoping someone with more scanning experience would be kind enough to offer advice before I go out and buy the 90mm 2.8 which isn’t cheap.
The distortion is consistent across films I scanned.

Thanks in advance for any help
