    ACR 8.7 release candidate, Nikon D750, Lens corrections tab

    ds2259

      I capture images using a Nikon D750 & AF-S NIKKOR 24-120mm f/4G ED VR lens with image quality set for NEF (RAW) + JPEG fine & image size set for Large. Slot 1 card saves the NEF files & slot 2 card saves the JPEG files. I download the images using Bridge CC Photo Downloader converting the NEF to a DNG while downloading. When editing the DNG image using the Lens Corrections tab in ACR it correctly recognizes the lens. When editing the JPEG image the same way it incorrectly identifies the lens as an AF-S NIKKOR 14-24mm f/2.8G ED and does not offer a choice for the correct lens. I hoping this can be fixed soon. A workaround that seems fairly accurate is to choose the AF-S NIKKOR 24-70 f2.8G ED instead for the JPEG images.

      I recently had to install Camera Raw 8.7 for CC Release Candidate Version: RC 1, Date: October 2, 2014 to recognize the D750 NEF files.

          What you’re seeing is normal.  Most lens profiles from Adobe are for RAW files only.  Many cameras do their own corrections, nowadays, so Adobe cannot assume the raw profile would work for JPGs from the camera as a general case.  For example with my new Canon 7D Mark II, which I'm awaiting raw support for at all, I can select vignetting, chromatic-aberration and geometric distortion correction as separate items on the menu to be used for producing camera JPGs.  Adobe doesn't attempt to interpret such proprietary information and apply the appropriate correction for corrections I haven't already asked the camera to do, they just don't supply a lens profile at all for JPGs.  The kit lenses for some cameras seem to be the exception to this, as well as a few other lenses, which I'm not sure why they've supplied profiles for.  You can also download profiles others have created, themselves, using the Adobe Lens Profile Downloader which you can find on the adobe.com site.

           

          If you are confident you won't ever have distortion or vignetting correction enabled on your camera for the JPGs it produces, then you can hack a copy of the Adobe-supplied raw profile for a particular lens to be for non-raws, by changing the whateverRAW tag from True to False, and put the modified profile in the user-created profiles area of your computer and it’ll be seen and used.
