Welcome to the Serif Affinity forums.

I don't think they're available anywhere else. But there are instructions on the Lensfun site for how to perform the profiling yourself, if I remember correctly. And that data should be usable in Photo.

You could then submit your profiling info to them to help others.

The Lensfun's test require some other applications and python installed, and it's a little complicated. But thanks anyway! Hope somehow future updates will add the lens. It would be great if we could use the same library as Adobe's.

Thanks for your help! I do find the profile for 35mm F1.2 DG DN is good enough for the distortion correction. 

Btw, I noticed chromatic aberration and Vignetting parameter were included in lensfun, do affinity photo uses these parameter?

The lens profile for Sigma 35mm DG DN is not available at lensfun, and the lens is not currently being calibrated.

Where else could I find its lens profile? Or is there ways to download adobe's lens profile and use it in Affinity Photo?

Thanks!
