From all this one might think that DxO have a better relationship with Canon than some other vendors. If that’s so, that’s good on canon - hopefully other vendors might consider their support. If I’m mistaken, then I’m not sure what to think.
Something I don’t understand: For the 105 Macro L-mount lens I can choose between 8 different bodies from 3 different manufacturers (4 Lumix, 2 Leica, 2 Sigma) and the 100-400 DG DN is also available for L-Mount. I don’t believe the optical formula is different, so why not allowing this lens also for L-Mount?
Indeed optical formula is the sams and we tried to support both mount with 1 calibration but it turned out there are some issues with Exif parameters we need, especially focusing distance. So for now we have differenciate calibration.
But we plan to catch up on L-Mount support.
Thank you for your reply @Marie. Are the EXIF parameters also responsible for the confusion of Sigma 35/2 C and Leica 35/2 APO? Never mind, I’m looking forward to see how far the catch-up goes.
that is what I find, specially with older bodies combined with newer lenses. Old body firmware does not necessarily report the complete lens designation and then, DxO has to draw conclusions from whatever info there is, be it in EXIF or other parts of the file.
Especially since the lens is delivering EXIF, but the camera might also redirect some entries (depending on manufacturer combination of body + lens. I saw that in two apps (Excire and PhotoStatistica).
And that one is sorted after lens model. Sigma hides their company name in a different field.
It must be an ongoing nightmare to get around in all these different proprietary naming systems. Lens and camera companies also alter their naming systems, I assume.
Imagine how easy life were, if there were an EAN code or MAC address etc. for each lens and camera model…
Btw, If you check raw files with a hex editor, you’ll see all kinds of repetitions of information that can include a full lens description and parts thereof.
I just used Graphic Converter to insert metadata into pictures made with a Laowa lens. As interesting as their products are, but no EXIF is a pita. How could I know the differences?
@Raisin54, the Sigma 150-600 DG DN OS Sport in Sony FE mount is in our planning, I don’t have a date of support yet. Here I’ve just provided what is on our short roadmap.
@ScottVincent, I’ll add the Canon EF 800mm F5.6 to the roadmap.
Marie,
does DXO already have a plan for the Viltrox lenses on the Nikon Z mount?
Unfortunately, Viltrox is one of the few companies that can supply lenses for the Nikon Z mount!!!
