I have just noticed that the latest version of DPP will now allow lens distortion correction for any lens;well at least it corrects my Nikon 18mm F3.5, Nikon 24mm F2.8 and my Olympus 50mm F1.8.
Has anyone else noticed this?
I am running that version, and it will allow lens corrections on
my Sigma 50/1.4 but not on my Sigma 30/1.4, so I think
there must be a set of lens codes it works with, and the non-Canon
lenses that match these are treated like corresponding Canon lenses.
Don't know for sure, but nice to see that DPP's usefulness can be extended.
