Zeiss Hologon 16/8 on M240

OK. I must have examples, but apparently not any that are easy to find and share. I've been doing a lot of ruthless editing lately to "drain the swamp" on my harddrive. I'll need to dig and locate a before-after pair that really show the change in both vignetting (pretty obvious) and the color shifting (less obvious in the examples I can find so far).

But in the meantime, you can take my word for it that both vignetting and color shift are addressed by Cornerfix.

While I take your word for it, it would be much better if you could find and post here some examples 🙂

Agreed. I'm trying to find time to search some out. A cursory search gave this pair. Its just downstream from the Herbert Glacier near Juneau, AK. You can see the dramatic removal of both vignetting and Italian flag. This happens to be the results of the Adobe Flat Field plugin, but Cornerfix would have yielded the same result. The lens was an older LTM version of the CV 21/4. A nice small and light 21 for long hikes 😀.

Hmm. Unable to upload images as usual. Maybe these attached images will suffice...

Thank you very much! The improvement is substantial.
This gives me hope.
