It looks like at the moment it already has the ones I need though. Btw fisheye-hemi is designed to make faces near the edges look less distorted than usually with a fisheye - which is something the Samyang seems. Or, if there is a lens profile already in ACD, but for a different body then you might be able to do the same. I wouldnt expect DXO OP, PTlens, Adobe and Fisheye Hemi lens correction to work as intended without a specific profile, that is with the assumption that the image is from a more conventional fisheye. That is what I meant when I said you might be able to get those public LensFun profiles you want and add them to ACDSee yourself rather than waiting and hoping ACD will do it. You mentioned that LensFun sometimes has lens profiles that are public that are not yet incorporated into ACDSee.
I suspect that even if you are shooting 1.5x APS-C and you use a profile for a 1.6x APS-C sensor it would still work well. For automatic CA correction and automatic vignetting correction, I guess, there might be some small differences though. Probably it would be the same for ACDSee. In other words, if you are using Canon 1.6x APS-C with a Tamron lens, but there is no PTLens profile for it for your Canon body it is okay to use the lens profile from a Nikon, Sony, Pentax, etc.
I recall some years ago that the PTLens developer, I think, said that it is okay to use a profile for a lens from other bodies as long as the sensor size is the same size or larger. (and do the minor differences in sensor size and how the sensor is implemented in camera make a difference? I don't know! And what isn't clear to me, is if you take a profile for a lens compiled for, say, a Canon camera and apply it to a Nikon, Olympus, or Sony camera, will the calibration numbers have any meaning for those other cameras? As I understand it, that calibration process is for a specific lens and body combination.
