Trail Version of Capture One 7 (Tamron)
Hi folks,
I've just been introduced to Capture One 7 and noticed that it doesn't list Tamron under lens profiles. It picks up my Canon (70-200 IS Mk I & II 2.8, 24-105 and 100-400) and Sigma lenses (35 f1.4), but substitutes Sigma for Tamron on 70-200 2.8. Is there any reason that Tamron (all models) is excluded?
I have to say that the default clarity and colour rendering is excellent compared to LR and DXO Optics Pro 9 - well done.
Thanks

I was just about to post something very similar. Tamron makes some very good (and POPULAR) lenses, for canon, Nikon and Sony mounts. LR does, in fact supply Tamron lens profiles, and I'd really like to see that happen with Capture One. Right now, I have both products, and I really do like some of LR's features, and REALLY like the fact that it has profiles for much more of my glass than Capture One does. On the other hand, LR looks a bit on the greenish side to me, and it doesn't appear to have Curves or levels for the color channels, the way Capture One does. I like LR's sharpening tool a LOT, by the way, and I also like the noise reduction on Lightroom a lot.
Lens profiles, though - a really big deal. Lightroom comes with many, and Capture One, not so much.
You know what would be a nice feature? The ability to update things like camera and lens profiles without having to wait for a new build of the entire application. I'm thinking that this could be a good way to break out developer time, and maximize efforts.

You're welcome to build a preset for any lens you wish and share it with your fellow users.
From an Official Support perspective, we do not have Lens Correction for any lens we have not evaluated first hand at the approval of the manufacture. As I understand it Lightroom builds arbitrary Lens Correction based on guidelines provided by the manufacture. As you can imagine, these guidelines are often a bit "better" then the lens performs in real life.
As such, we've made a decision that if the lens is in-house, we will review it and build support for it ourselves. If we do not have it in-house, we will not provide official Lens support in the software.
If Tamron would like to provide us with lenses, we'd be happy to evaluate them and build Lens Correction to include in the software.0 -

OK, a question. What do you mean those guidelines are "better" than the lens performs? Either a lens profile addresses (and corrects) issues with the optical performance of a lens, or it doesn't. How can the guidelines for lens performance be "better" than the lens and actually do the job they're intended to do?0 -

The adjustments compensate beyond what the lens actually provides. In other words, the results are not true to what you have captured but instead overcompensate for bad optics. In our opinion, the Lens Correction should correct for distortion and falloff (as well as CA/Purple Fringing) but not provide you with a false representation of a poor lens. The results should be true to the performance of your lens.0 -
Drew's point is simply that the manufacter's claims for a lens' performance are often at odds with the reality - "ideal world" MTF scores that production lenses don't achieve, for example, or unsupportable claims for CA, distortion etc.
If Adobe is basing its Lr lens adjustments on technical data provided by the manufacturer rather than on the basis of hands-on evaulation, then the resulting profiles are likely to be inferior compared to physical testing of the lens in question.
(Before it gets interpreted as such, none of the above is meant to be critical of Lr or of third party lens manufacturers: I use Lr too, and I also use Sigma lenses).

Trying not to crosspost,
-> here
(please delete the one that's wrong)
but I'm not sure where my problem goes
How does one go about creating and storing a lens correction profile in Capture One 7 (or 8, in my case).
I don't mean the LCC profile, but distortion correction profiles for my Tamron Zoom lens.
Thanks,
Michael.0
