@zstomp please provide a sample raw file.
@Beep6581 Sorry, I thought RAW wouldn't be necessary. Here you go: https://gofile.io/d/rUAiJD.
@zstomp I get an error following the link:
Error: EPROTONOSUPPORT: protocol not supported, stat '/usr/src/app/index.html'
@Beep6581 The link still works for me, hopefully that was a temporary problem. Please try direct link.
The sample raw file uses a Sigma 10-20mm f/4-5.6 EX DC HSM
. Lensfun (DB version 1, just updated) has two profiles for that, crop factors 1.53 and 1.62. The Canon EOS 1000D has a crop factor of 1.6.
The profiles differ in crop factor, but RT seems to ignore it
How have you established that?

That's right.

The 1.6 profile has no distortion correction, but the one that is automatically or manually selected has it.
RT chooses the first lens from a list created by lensfun. The list is ordered such that the "best" match appears first. https://github.com/Beep6581/RawTherapee/blob/86471c88e0727c0e85766b6da8c088c836cc3105/rtengine/rtlensfun.cc#L481
Lensfun has multiple profiles for some lenses (e. g. "Sigma 10-20mm f/4-5.6 EX DC HSM"). The profiles differ in crop factor, but RT seems to ignore it and always select the first one in the list in auto mode. Additionally, only the first profile is available in the drop box in manual mode.
