I have not but that would not be my first choice in a lens for a 7D Mk II. If it is having issues, remember Tamron has to guess at how Canon cameras work. If they guess wrong there is compatibility pronlems. May be the case here.

Is the lensora report based on actual testing... or merely theoretical?

I'm wondering ... because there's a well-established history of 3rd party lenses that should be compatible based on the mount, but have problems anyway when a new camera model is introduced that did not exist when the lens was designed.

At the same time, if you contact the lens vendor for support, they may be able to provide better data and sometimes they can re-chip or re-flash firmware into the lens to upgrade it to a compatible state.
