I downloaded LR 4.1 RC today. Some of my lenses are not profiled in LR so I then downloaded Lens Profile Downloader Preview 3 to see if there are any profiles available for download. For some lenses I found profiles, but they were not done on the same body that I have (same sensor size though). Can I use profiles for lenses if they are for a camera body that is different than mine, but still the same sensor size? My understanding is that wiht a lens profile LR will automatically correct distortion, vignetting, and CA. Will that work if my body is different than the body used to profile the lens? Thank you.
Yes that's possible.
I downloaded it with Adobe Lensprofile Downloader
In LR ,I can choose it under Custom.
I have Panasonic Lumix G 20mm -F 1.7 ASPH on Panasonic GF1
and the available profile is (same lens) for Panasonic Lumix DMC-G3.
Thank you very much for the info!
You can find this statement:
Regarding lens vs camera+lens combinations. Generally, Adobe only supplies 1 profile per lens. Differences between cameras (e.g., crop factors) are automatically taken into account when applying the profile
