How to disable distortion correction for micro 4/3 lens

Jul 7, 2010 7:36 PM

Hello,

 

I have an Olympus E-P2 and Panasonic 14-45mm lens.  Adobe Lightroom 3 and Photoshop CS5 appear to be performing some very heavy-handed distortion correction at the wide-end of the zoom (running the file through a different raw converter yields dramatically different results at the edges).  This is without selecting any lens profile or enabling manual correction.  How can I disable this?

 

Thanks,

 

Dara

 

P.S. Strangely, ACR 6 is not doing any correction of chromatic aberration.  Given that the system is set up to try and fix distortion and vignetting automatically, it would make a lot of sense to fix CA too.

    The distortion correction is applied automatically based on the available metadata (from the camera + lens system). The resulting shape of the image should closely match the result of shooting JPEGs. It cannot be disabled in CR/LR.

    Your could try using another converter that doesn't apply the corrections, then import the resulting TIFF into CR/LR. I don't really suggest that approach, though.
