I find the AWB in the A7 to be somehow sensitive to aperture, for reasons I can not come up with a theory for. This is true unmodified and with the v1,2, and 3 thin filter mods. Any ideas why?
Also, after a better technical brief from Ilija at Kolari I have a camera switched to the UT mod and share some comparisons.

PS I was looking at the "hot" shots from the UT. At AWB they almost all were coming in with temps higher than the more normal looking shots, and in most simply bringing the temp down from say 5500 to 4200, gave a similar look. Still I had a few outliers, which seem to have grabbed something besides just a hotter temp.
Simply bringing that down still left a "washed" look, but really blue. It was responsive to editing, though I could not fully recover it to what the same lens was doing in the last post. The last shot in the previous thread is nice, for me, though I would desaturate a bit further on review.
I stopped here with this one.: DSC01375-2 by unoh7, on Flickr
The M9 was not making shots to my taste here either. Here it with a similar angle. These were coming in OOC at 4200. They seemed to have the same range of tonal variety as the "normal" UT shots, though less saturated, and with a somewhat different mix.
This has some editing, so should be compared to second UT shot, though it was nothing like the first UT shot unedited.
Now another variable is speed and the 28 cron is stopped down, while the 90 TE, which is famous for flare, is near WO, where it also has low contrast. If you look at the last TE shot in the previous post, though, it's clear something "happened". Flare of some sort could explain that. The lens cannot be used without a serious hood and is WAY more strange with flaring than any 90 or 100 I have.
The magenta in her jacket is really different. Next time I will use the 90 Summarit which does not change like the TE at faster apertures and has no where near the weird antics of the TE with the sun.
In short during this shoot the UT gave me some of my best shots and also my worst.
