Several readers noticed that the caption on yesterday’s image indicated using the Zeiss Otus 28mm f/1.4 APO-Distagon. That image was NOT taken with the Otus, but with the Sigma 28mm f/1.4 DG HSM Art.
Ambiguous lens names
In other words, the same value of "28.0 mm f/1.4" is seen for a Sigma 28mm f/1.4 DG HSM Art, Zeiss Otus 28mm f/1.4 APO-Distagon, and Nikon AF-S 28mm f/1.4E ED— no difference. Sometimes I miss catching it manually and then I have to go back and redo.
Even exiftool shows that the values are problematic; with the Sigma 28/1.4A mounted on the Nikon D850, the brand name "Sigma" does not appear even once anywhere even in the full EXIF dumped by exiftool (there is no 0xa433 Lens Make or 0xa434 Lens Model exif code, for example).

On the presumption that “chipped” lenses have identifying information, it appears to be a bug in the Nikon D850 and all Nikons—Nikon apparently feels no need to include the lens make or model. Furthermore, the Sigma 28/1.4A is really an "E" lens in Nikon parlance (electronic aperture) and that is not noted either (it”s recorded as a "G" lens).
What is available in Photoshop
Within Photoshop, the amount of EXIF is severely limited. It should not be confused with the full payload available with external programs like exiftool; the Photoshop-accessible values are woefully truncated. I have asked Adobe to add more fields and will ask again with specifics when time allows.
Below this is ALL the EXIF info available in Photoshop (GPS is included also for cameras that have it):
