Fujifilm GFX100 BUG: Sets Mandatory Lens Correction Profile for Unknown Lenses
I’ve long disliked mandatory lens corrections (vignetting, chromatic aberration, and especially distortion because of distortion correction.). Many lens vendors including Fujifilm rely heavily on heavily to make less than ideal optical designs. Nikon even claims claims ultra low distortion with its Nikon NIKKOR Z lenses, many of which have severe barrel distortion.
Adobe Camera Raw contributes to the situation by not offering any way to disable the flagged corrections. Most of the time this is OK because lenses needing correction would visibly suck without it. But there are many cases where all is well without it.
The Zeiss Otus 100mm f/1.4 APO-Sonnar and many other fine lenses do not need corrections.
Showing the folly of such an approach, the Fujifilm GFX100 now shows an outright BUG in setting a mandatory-correction EXIF flag for unknown lenses adapted via a "dumb" adapter. The camera cannot possibly know what lens is attached, and yet it sets the EXIF flag mandating correction! It concerns me that it might actually be creating color fringing—not yet sure. I’ve reported the problem to Adobe, asking them to add a feature to ignore required lens corrections or at least fix this bug on their side
Update: Adobe has responded and tells me that the setting is a “no op” (meaning nothing is done), and that it looks like a bug to be fixed.
