Cornerfix profiles for Leica Summicron-M 35mm/2 (Asph.) on Sony NEX-7

In a previous article I already described how to post-process images which were taken with ultra wide legacy lenses on a Sony NEX in order to eliminate the magenta cast in the corners. I use the free software cornerfix (which is available for Mac and PC).

In order to get the best results, you should create your own lens profiles. Therefore you can follow these instructions. I recommend a flat field reference file which is based on a picture through a matted glass panel.

But as you may not have such a glass panel at hands you can also download one of my profiles and give it a try.

If the profiles work for you, then please leave a comment or send a note.

I also created some profiles for the Voigtländer Ultra Wide Heliar 12mm/5.6 and the Voigtländer Super Wide Heliar 15mm/4.5 on the Sony NEX-5 and the Sony NEX-7.

Here is an example of an uncorrected shot with the Sony NEX-7 and the Leica Summicron 35mm/2 @ f7.1.

This is the same image but additionally corrected with cornerfix and this profile (5.6).
