No.
I have been trying to see what is needed without experimenting by modifying
lensfun code, but I failed.
My idea was to use the Fx special effects of ImageMagick to experiment with
various correction formulas.
But I have not
Dear all,
I use a "smc Pentax-DA* 60-250mm f/4 ED IF SDM" on a "Pentax K-1".
This lens is not designed for full frame, but its only drawback is a strong
vignetting.
This vignetting does not show in the viewfinder, it only shows on the sensor,
which means it is "pixel vignetting".
