A number of people have contacted me to ask how much lens correction there is on the new Leica SL. Or, more accurately, how much lens correction there is on the new SL lens, the VARIO-ELMARIT 1:2.8-4.0/24-90mm.

Below are the comparisons for an image shot at 24mm - the uncorrected image is from AccuRaw. (The original image is courtesy of PhotographyBlog).

I'm sure you won't need me to tell you which is which(!).






For those interested in the gory details, here is the content of the correction:
