Zeiss Otus 1.4/85 ZE lens not listed in Bridge Metadata

  • Updated 4 years ago
The latest release of Camera Raw 8.7 states that the Zeiss Otus 1.4/85 ZE is supported. Whilst in Camera Raw it is listed in the Lens Correction Tab, in Bridge the lens is just described as 85mm in the Metadata section. I also have the Zeiss Otus 1.4/55 ZE lens and this is correctly described in Bridge metadata.

Any ideas why this is would be appreciated - whilst not really an issue it would be nice to have the accurate metadata listed.

I'm running Windows 7 x 64 Pro.

Hello Ian,

The EXIF metadata for this lens is a result of communication between the lens and the camera and what the camera ends up writing into the raw image. Bridge is merely reading what the camera/lens combination generated. The profile for this lens was based on this same metadata and it should auto-match correctly when ticking the "Enable" box in the corrections panel.

Is profile auto-matching working for you?

If not, would you mind posting a sample raw file for me to look at so I can compare what you are seeing to our internal test images?

Thanks!

Hi Chris,
Many thanks for your prompt response. In camera raw all seems ok - when checking the 'enable lens profile correction' box the lens profile is correctly listed and is applied to the file. I It is in Bridge itself that I see the issue. In the Metadata section in the 'Camera Data (Exif) section against the 'lens' label I just see 85mm rather than Zeiss Otus 1.4/85 ZE. As I say for the Zeiss Otus 1.4/55 ZE the lens is correctly listed so I was expecting the same for the 85mm lens.
Hope this explains more clearly what I am seeing.

Cheers
Ian

Thanks, Ian.

I also see "85mm" for the lens name tag. Similarly, the Nikon mount version is listed as "85 mm f/1.4" I also confirmed that the 55mm OTUS lenses display the full lens name in the Camera EXIF as you point out.

This metadata is not something Bridge or ACR/LR has any control over as it is written by the camera based on what the lens communicates to the camera. I'm not certain why the full name is not written to the metadata for the 85mm OTUS vs. the 55mm OTUS. That is a question for the lens and/or camera manufacturers.

Hope that helps,

Thanks again Chris,
I'm glad you're seeing the same - reassures me that there's nothing amiss at my end. It is strange that this issue exists with the 85mm and not the 55mm. I do know that when I first bought the 55mm lens you did not provide support for it and so in Bridge 55mm was displayed in the lens name tag, however once support was provided this changed to the full lens name, so I was expecting the same for the 85mm lens.
However it's not a big issue but maybe I will ask Zeiss/Canon the question.

Thanks again for taking the time to check this out
All the best

Hi Chris
According to Zeiss about the naming convention of the lens when files are imported into processing software. Per Zeiss, the lens CPU simply communicates a number - it is the s/w which takes the number and converts it into an alpha description such as the lens mfr and name.
So they are saying that Adobe should be able to sort this issue?

Hi Ian,

I checked with my colleague who originally implemented Zeiss lens support and this in fact true as you discovered. I'll fix this in a future release for the 85mm. Lens profile support will continue to work as expected.

Cheers,
