For example, Lightroom identifies the 7-14mm and 17mm as having both types, while the 8mm FE and 25mm only have CA correction. I wonder if perhaps older versions of Lightroom were doing automatic distortion corrections but not anymore (perhaps if there were complaints such as the OP has?), or if there is some setting I need to change to implement automatic distortion correction.Įdit: Some of the Pro lenses do have distortion correction, after all. In any case, I’ve oftentimes have had to manually do even more CA correction for purple fringing. The info button says it’s applying built in CA correction for the specific lenses, but it doesn’t say anything about distortion correction.

It is, however, correcting for chromatic aberration. This is why I haven’t noticed any de-fishing. As far as I can tell, Lightroom Classic CC isn’t automatically doing distortion corrections on the Olympus Pro lenses I’ve looked at so far. I’m getting closer to solving my problem.

Thank you for any information you can give me. Perhaps someone has looked into this and can tell me.ġ) Does the LensFun make produce a usable stand-alone tool? Either a console app or a GUI?Ģ) If so, can it be called as a plugin from a pixel editor?ģ) If not, what does the make give you? Perhaps I can build a 'swift' wrapper around it.Ĥ) And, perhaps most important, is there a downloaded version of LensFun that is already built? I am not sure I have the proper libraries on my system to build it, and am not sure I want to install what I might need. I thought there might be some information about that on this forum, but a search did not show me anything that answered my questions and I decided to ask specific questions. When I visited the LensFun website all that they seemed to have was a source download and some 'makefiles' to create the tool on my system, but no real information on how to use it. Because of that I decided to look into LensFun with the idea of using it as a plugin for some of my pixel editors. Several of the others say that they do, but either require manual correction or do not handle my Olympus 8mm FE properly.

Only one of the photo editors I have on my Mac (Dxo's PhotoLab) actually seems to do automatic lens corrections.
