Please write down your thoughts because citing a video does not work. :-) You are right, Lightroom applies lens corrections automatically for µ4/3 and Fujifilm lenses. In Darktable, you have to switch it on explicitly. That is not a big difference in my opinion, though. A much bigger difference is that at least for µ4/3, you can't even switch that off in Lightroom I think. But I don't see any point in doing that anyway. µ4/3 and Fujifilm X both store the lens correction parameters in the lens, which is then embedded into the RAW. So, no extra profiles are needed. Hopefully DT will be able to extract that info as well and pass it to Lensfun. But we are far away from that because there is not even a description how the parameters are stored and which formulae to apply. At the same time, lens correction is part of the mount specification, and lenses are designed to be corrected afterwards. And yes, this *is* a trend for lens builders: They build lenses to be digitally corrected. Seasoned photographers may not like that but there we go. My personal opinion is that every lens design is a tradeoff, and in the digital era, there should be other priorities (like weight, size, price) than the unnecessity to correct.
