Hi, I have the aforementioned lens, and it gives me a green color cast near the edges (vignetting) that I with lensfun would autocorrect. The cast is strongest when shooting in low light (i.e. with large apertures and higher ISO).
The thing is, when I try photographing e.g. a white wall at different focus distances, lensfun's vignetting correction always manages to remove the color cast, but on more real-world images the cast is still visible. In fact, vignetting correction actually makes the cast more apparent in such images. I'm shooting on an Olympus OM-D E-M5 Mark II and for the record, my Olympus 45mm f/1.8 lens does not show such a color cast. Here is an example raw file that exhibits this issue (see the window, the cat's fur, the sweater, the stair steps): https://www.dropbox.com/s/ik100ywbct4z00n/_3250430.ORF?dl=0 Is there something I could contribute to help lensfun autocorrect this color cast? ------------------------------------------------------------------------------ Transform Data into Opportunity.
