Thank you for this review and keep them coming. I've been looking at this lens for a long time now and once again, I have to put it high on my list! Perhaps you can post an image that shows some of the effects you mention before and after cleaning up in LR. Glad to hear that any cleanup needed is minimal.
Bob, I've now carefully fine-tuned the lens compensation app settings (white wall in the loo) for the CV Ultron 21 (illumination: +15, magenta-green: -3, and yellow:blue: -9), and IMHO it performs very well at correcting the illumination and colour cast problems with this lens, with the corrections written into the raw file.
To demonstrate, I've loaded three images (cold and grey winter day here, so rather boring), all shot at F/5.6 and with luminance equalised on the wall blocks below the window in the centre. The first is with the lens compensation app turned off and no correction, the second is a LR corrected version of the first using a radial filter (inverted) with increased exposure + colour temperature correction - rather hard to tune. The third was shot with the lens compensation app turned on, but with no correction other than to adjust its exposure so that luminance on the blocks dead centre was set to the same as for the other two. Suggests to me that the lens compensation app is the way to go, particularly given that colour cast correction component (as opposed to the vignetting) seems to be stable certainly through the lower part of the aperture range - I've not tested its sensitivity to focus distance, which might alter given the change in distance between the back element and the sensor.

Ultron 21 - corrections applied with radial filter in LR6
Ultron 21 - corrections applied via Sony's Lens Compensation App - only minor changes to match other images
Sorry, I have been swamped with work recently and hence haven't had any chance to post as of late. Great to see that this thread is still going strong, as it is heading towards 1,000 pages.
Charles, you made the most out of the available light. The colors in the fallen leaf shot are beautiful.
Ronny: Impressive macro work with the MP 100 again. As somebody who is always struggling with color balance, I'm always impressed by how naturally beautiful your pics look.

@ Peire: Hi there, sorry for the late response (being on the road). As the title diplays, it was taken recently in Goult, Vaucluse, Alpes-Côte d'Azur (Place de la Liberation, BTW). And thanks of course for your interest!
Ronnie are these damselflies or dragonflies? Always wondered about their size. In our area dragonflies are usually fairly skittish, so guessing damsels perhaps??
They are beautiful, and well captured in your photos.
