I noticed it using the Daylight WB outside. Though when I picked the LR Daylight WB I also had to adjust quite a bit towards the magenta. It's possible there was just something about the light today?
Hmm, also, I have been using the Huelight A7 Standard color profile. Maybe that is related. It is possible I have just forgotten what this profile is like, since I've been using the Mk2 for the past month and there isn't a Huelight for that so I've been using Adobe Standard.
This picture is set at 5450K, +33 Magenta in LR5, but with the Huelight profile. When I switch back to Adobe Standard it is much less green.

Now, where do I go to tweak my Auto WB?
On A7 series: Press Fn button, go to the WB settings, select it, go to the WB setting you want to tweak(AWB/Daylight/etc...), push right.(Must have WB in Function Menu set, just above Custom Key settings)
On the NEX-7 it's very similar: Go to the quick Nav screen, go to the WB settings, click the Option button.(Must have "Custom" set in the Custom Key settings and WB set in a custom slot)
I should add that you can have a unique WB offset for each WB mode.

TY so much guys

You can adjust the presets with the A-B and G-M fine tuning adjustments in the Sony. At least on this quick test, shifting +2 Magenta and +2 Blue in the Sony bring the 'As Shot' and the eyedropper settings into line.
I'm starting with Michael's suggestion and get reading B2 and M2 in the Auto mode.
I have to say it's nice to see these tweaks
Can we now effectively set a minimum shutter in Auto mode?

Not sure you need to tweak AWB since that should be analyzing the sensor output, which already considers the effect of the filter stack. I think only the 'fixed' settings (Daylight, Tungsten, K, etc.) should need adjusting.
And I'll work on that minimum shutter speed next...

Still no FW update for minimum shutter speed.
Fuji have been providing FW updates fairly regularly, Samaung have announced they will update the FW on the NX1 monthly, Sony? Well FW updates will come when you upgrade to the next generation.

My A7r is back to Kolari vision for a minor issue. No problems other than I am very keen to test it with my M lenses
Charles, may I ask what is the problem? My A7s mod will be done by the end of the week but I would not be able to test it myself in another month (the agony ). I loaned mine out to a cousin for one of his video projects so I have to ask him to check it for me. So far I see the WB problem (not a big deal since I tend to change WB in post) and the possible incompatibility with my adapter (that would take a good while to test).

I've been using NEX 5, NEX 5N and A7R cameras with M-mount lenses since those cameras first came to market, and now I'm seriously contemplating purchasing an A7S and having it modified by the particularly helpful people at Kolari Vision. However, I don't think I've seen any images taken with the modified A7S, as opposed to the modified A7 or A7R. I expect the modified A7S will be without the colour shifts that afflict the modified A7 (and also the A7R), owing to the A7S's large pixels and gapless on-chip lens design; and that the A7S will maintain the significantly reduced edge and corner smearing of the modified A7 or A7R. Can anyone please confirm that this is the case? Thank you. Nettar

I would say so. My ZM 15 exhibited strong vignette and heavy color cast on the A7R, but barely noticeable on my A7s. Smearing reduction should be the same as other modded A7/R.

How can I center the focus mag box without using wheels? i.e. is there a "one push to center" somehow?
On my A7r it's the trash button (C3), I don't know why. (I focus magnify, move it off enter and C3 brings it back). I've tried changing C3 to other functions and as long as you are "in" focus zoom and can see the focus box it resets the position. I found it by complete accident.

I see some funky WB/ color issues going on with both these shots as well as the one Taylor posted on the previous page. I have no idea if the mod contributes or not but I have seen this myself with a few Sony's thus far (both the RX1 and the A7r). With the A7r, it's highly lens dependent.
The symptom is that if you attempt to do an auto WB correction on a neutral (such as on the grey concrete in your shot of the bridge or on the road/ sidewalk of Taylors street shot), the blues (usually the sky) will go way magenta/ purple. Unfortunately, a global, manual correction of the WB to counteract this causes things to turn green and/or cyan. The fix is to adjust the blue hue after setting the eye dropper WB using a neutral (or after setting the correct WB temp for the light, however that is arrived at). In ACR or lightroom, this means moving the blue hue towards the left (aqua). Doing so corrects the WB with both your shot and Taylors.

Next A7 expert question:
Any way to get a "shortcut" switch to toggle EVF/LCD? Without diving into menu?
I've always thought that you had some of the best white balance in your photos - really, I've thought "wow, the colors are perfect" many times when looking at your posts.
but. . .not so much lately. They are either quite purple (these) or quite green (earlier).
Any ideas why? Not a criticism necessarily, just curious.

Boils down to change and incompetence.
A7 RAWS are killing me!! I find the WB is hit heavily by push and pull for me, unlike the Leica RAWs which hold their character really well with the same sort of moves.
Worse I have been tweaking the auto WB looking for a sweet spot. IE I have over compensated for the green. At some point hopefully I will get it closer. And learn some more tricks in LR.
Add to this we do have alot of blue light here right now, with deep blue skies and reflective spring snow.
Either I will figure out the A7.mod WB or the M9 will be back from NJ
