Lightroom: Lens profiles don't work on micro 4/3 lenses.

Why doesn't lightroom allow Lens Profiles for micro 4/3 lenses?

I get that the micro 4/3 format has lens profiles built into each lens already, and that those corrections get applied automatically all the time. This may reduce the *demand* for user generated profiles, but it should not hinder the implementation of them.

Just run the manufacturer's lens corrections first, and then run any user generated corrections on top of those.

Example. The Olympus f/1.8 8mm fish eye lens is *amazing*! The shortest working distance is about 8mm in front of the light shades.

I would like to make custom lens profiles for this lens to:

1: Fix residual chromatic aberration when focused very close.
2: Correct for barrel distortion of the FE lens which the stock profiles did not address.
3: Correct chromatic aberration induced by an underwater camera housing, which the factory lens profile doesn't know about.

I downloaded the profile maker and made a test profile. I couldn't get it to work with the raw files, but if I save an intermediate TIFF image and import that, Lightroom will recognize the camera and lens from the metadata in the TIFF and pull in the lens profile I made.

This proves that the profiles are working, but it is just plain silly, since it breaks the whole concept of Lightroom, which is to always work from the original files and NOT save intermediate images.

Hi Ralph,

When you created the lens profiles did you first convert the RAW calibration images to DNG and import those into your LCP project, or did you use JPEG or TIFF?

I'm asking because profile creator will set a specific element value in the LCP that tells Lightroom/Camera RAW what type of image the profile was generated for.

Open one of your profiles and search for "stCamera:CameraRawProfile="

A value of "True" supports RAW. "False" is for JPEG and TIFF.

Ideally, you should generate the profile using the RAW images (converted to DNG) to get the most optimal profile for use with RAW.

If this doesn't sort it out for you, please let me know.
