![]() It helps to create a DNG file with the correct expected values using the camera, than compare the three EXIF tags and copy the values over. Note that the first tag requires a 32 bit integer and the other two only a 8 bit integer, usually meaning "35mm" is differently encoded. ![]() "0x001dFocalLength", "SRFocalLength" for Shake Reduction, and "LensFocalLength", an extra record that keeps all Lens information. This lists three (3) relevant EXIF tags that store the focal length. I've looked at a few options online and on Apple's App Store, but it's hard to tell which one would work the best (though some clearly seem to be not so good).Įven with Exiftool command line tool working on Mac (which is possible) it will be tricky to correct the EXIF data. ![]() And the adjustment fields have to include things other than date and time-especially focal length. do any of you folks use an app or plugin to edit EXIF? I'm talking Mac-compatible software, preferably 64-bit since Mojave's about to get restrictive about such things. And the only other thread I found on this issue is about 7 years old and deals with an app for PCs, not Macs. LR, of course, permits date and time changes, but nothing else. The worst thing about that, of course, is that my K3ii's shake reduction didn't work quite as well as it could have, though the images themselves look fine.īut the fact that those images are now attributed in LR Classic to a lens with a focal length of 35mm is annoying-even if the photos themselves would stay the same even with an edited focal length. I don't do it very often at all, but it's annoying when it happens.) (Not that this is the first time I've missed the step of identifying the correct focal length of one of my many old-school lenses. But I apparently missed a step when I switched from my K 35/2.0 to the A 100 macro, and all the macro images were logged as having been shot with the 35/2. I just shot my first session with my "new" A 100/2.8 macro last Friday.
