Did you know that you can use the free Adobe Lens Profile Creator Tool to create lens profiles for less common lens/camera combinations? All of the information that you need to know is here: http://labs.adobe.com/technologies/lensprofile_creator/

Note: in Camera Raw and Lightroom, the lens profile popup will only display the profiles appropriate for the file type. So if you’re looking a raw file, you get to see raw-based lens profiles. If you’re looking at a jpeg, you get to see non-raw-based lens profiles. As you can see, we have many more raw-based lens profiles available than non-raw-based lens profiles. This is due to the fact that lens correction quality for non-raw files (JPEGs, TIFFs, etc.) can be very problematic (this is because it depends on where the JPEG/TIFF came from, and how it was previously processed). For example, a JPEG that comes straight out of the camera is very different from a JPEG that somebody created from a raw file in ACR. If you try to apply the same non-raw-based lens profile to these two cases, you can get quite-different results (even though they’re both JPEGs from the same camera and lens).  Thank you for that in-depth information Eric!

    Hey,
    I didn’t know that – thanks for sharing. :-)
    I will have a look how I can implement this in my PS. :-)

    Great info!

    Does this correct “wavy” and “mustach” distorsions as well?

    I’ve been looking to buy a wide angle lens, but all (even Carl Zeiss) have wavy distorsion and if you’re photographing in a city with lots of straight lines this looks very wierd even at low distorsion rates. Help appreciated!

      Yes, ALPC does handle wave / mustache distortion.

      Since you mentioned Zeiss: we do ship lens profiles already with ACR and Lightroom for the Zeiss SLR lenses. Some of these lenses, such as the Zeiss Distagon 21 f/2.8, are fabulous lenses but do have characteristic wave / mustache distortion. Our profiles remove this distortion. Since we already have profiles for these lenses,you may not need to build profiles yourself!

    Can you please please please do a video tutorial on this? I use an E-5 and there are no good reliable profiles for my f2 14-35mm lens
    thank you!

      I don’t know how soon I will be able to get to this, but in the mean time, if you go here: http://labs.adobe.com/technologies/lensprofile_creator/

      The information under the Getting Started tab and then click on the link for the “Lens Profile Creator User Guide” It will give you step by step instructions as to how to create your own profile. I hope that helps, -j

    After updating to Photoshop CS6 and Camera Raw 7.2, I am most unhappy to find that the lens profile data for chromatic aberration is no longer used (as it was in CR 6). Instead, there is an automatic CA correction, regardless of the lens profile I select, that works fine in many cases but is much less efficient with my wide angle lenses. Specifically, it does fine with CA fringes on sharp edges but leaves CA in blurred backgrounds largely alone. CR 7 is clearly superior to CR 6, but PLEASE give us back the old manual controls and full lens profile support!
