Manufacturer profile vs specific lens profile
For some Fuji lenses, Phase One provides a specific profile, for instance for the 10-24mm.
For other Fuji lenses such as the new 16-80mm (and also for the lenses for which Phase One provides a profile), the profile menu indicates "Manufacturer profile". I understand that this is the profile provided By Fujifilm and which is somehow part of the raw file.
However, for lenses such as the 10-24mm where both profiles are available, the results are different. How is this possible, and which one should be used?

Which produces the best results? If you take an image of something that would make it obvious (such as a boring head on photograph of a brick wall) which one gives you better correction of distortion?

Honestly, difficult to say…
The Phase One profile seems to apply a stronger correction, and crops a little bit more. As for a preference to one or the other, I don't know.
I think what I was getting at but did not formulate clearly was: if there is a manufacturer profile, why did Phase One create its own profile in some cases?0 -

Usually because there is a feeling that for some lenses in some usage situations there may be a better profile possible.
Historically and perhaps before agreements with 2 significant manufacturers were completed, the access to the Manufacturer Lens Profiles may not have been fully available for some reason. In which case a C1 profile might have been a necessity.
More recently lenses from the manufacturer's concerned seem to have defaulted to the Manufacturer values rather than pass through the full C1 assessment process and have a new profile created. I can't be certain about that but it is an impression I get. Maybe an owner with recently released hardware could comment?

In the case of the 10-24mm, I think I saw the "Manufacturer profile" first, only inmore recent versions (couldn't say when) did the Phase One profile appear. 0 -

That is possible of course.
If someone decided that a different approach than the Manufacturer Profile might be worth producing they might have put an example of the lens through the lab analysis.

That results are different is a result of different corrections in the respective profiles, obviously.
Capture One first tries to apply their lens profile. If not available, the manufacturer's profile. In case that also does not exist, you have the manual options with sliders and checkboxes.
Based on that logic, Capture One assumes that their profile is best. 😉0 -
