Really intriguing.
What if you try 10600, following James1's findings?
BTW the "grain" is so sharp, it's strange you measured such a low actual resolution.![]()
There are several reasons why i didn't go the 10600 ppi way. :
Primary one : It didn't work propperly :bang: Histogram settings were not visible in the resulting image. Allready contacted Silverfast about that.
Second : For medium format (my niche) way too big files and way too long scan processing times.
Third : I'm not sure if it is 10500ppi in both ways (X-Y).
I did peform an optical resolution measurement with an USAF-1951 target (bought from Silverfast when they offered a 30% price reduction) and came out at circa 3650ppi.
Scandig has used same target and came out at 3450ppi :

However, for me the results of the Opticfilm 120 are very satisfying and i start to enjoy working with Silverfast (sometimes when it behaves)

That sure is a lot of grain! I have never seen anything quite like that on my P120 unless my negatives were really underexposed, but then again I only shoot Kodak negative film, so could potentially be a problem with Fuji's emulsions and the light source in the OP120.
Recently i did shoot 2 rolls of Kodak Portra 160 and didn't have any Aliasing effect issues with that film. Scans very good. Guess that Portra 160 will become my "standard" for the future.
