Question

Lens Profile - Canon EF 300mm f/2.8L IS II + TC 1.4x III or TC 2x III not detected

Hi.

I am using the latest ACR 9.12 but this happens for very long time... I used 7D Mark II, 6D and 5D Mark IV to verify this.

When I use only the EF 300mm and I check the Enable Lens Corrections box, automatically ACR detects the lens and puts Make, Model and Profile fields accordingly.

But when I use Canon EF 300mm f/2.8L IS II in combination with TC 1.4x III or TC 2x III, ACR does not detect them. I need to change manually the Make to Canon, but the behaviour is different for each set when I change the maker:

EF300 + TC 1.4x

Setup: Custom

Model: Canon EF 300mm f/2.8L IS II USM + 1.4x

Profile: Adobe (Canon EF 300mm f/2.8L IS II USM + 1.4x)

It is OK.

EF300 + TC 2x

Setup: Custom

Model: Canon EF 600 f/4 L IS USM

Profile: Adobe (Canon EF 600 f/4 L IS USM)

It is wrong. And I need to change manually Model to Canon EF 300mm f/2.8L IS II USM + 2x

Thank you.

    It would be helpful if you could post sample raw files that we can use to investigate the matching issue. You can use a service like DropBox or similar.

    I took three photos and put them in WeTransfer: https://we.tl/GM7aOLQDNy

    Even using the lastest DNG Converter, the DNG files have the same symptoms. The lens profiles are not identified.

    Thank you,

    Marco

    Yep, I'm getting the same thing with the latest version of ACR. I also check the xmp info, and the correct info is there, so ACR should be able to pick that up.

    What does the actual camera data show in the raw data info? Is you camera recording that you're using those converters?

    If it's in the raw file, ACR should pick that up. Looks like a bug.
