Creating a lens profile

In order to achieve near macro-photography using Olympus E-M5ii, I am testing non-Olympus lenses, currently a Componon-S 4/28 enlarging lens designed for low magnification. Is it possible for me to generate a correction file for this camera/ lens (at various magnifications (1:1 to 5:1), apertures, etc) which can then be used within Photoshop's processing of the RAW image, for instance by providing the necessary information to adjust vignetting?

The tool, Adobe Lens Profile Creator, appears to have been discontinued. Is there a work around?

Thank you.

The Adobe Lens Profile Creator hasn't been discontinued, however, adobe is in the process of

changing some download links.

This link should work:

Thank you for the link. I am pleased that it is still possible to use these tools and apply the corrections.

The smallest calibration chart supplied is nominally 7.25x10.5", which is larger than any of the images I wish to (or can) take with the lens/ camera combination.

According to the instructions, the chart should be ca 1/4 the area of the image screen. So the chart should be ca 6.5x8.6 mm, at 1:1. The instructions do not seem to have a size/ magnification criterion, but I may be pushing the validity of the method well beyond its design limits.

Is it possible to do the calibration with downsized versions of the charts?
