I read all threads already but strange thing is that I did not had this problem before. I shoot already a plenty of red flowers and never had a problem as I was really careful with exposure. This is the first time I run into. Yes, I did have slightly overexposure when red color was dominant but very rare and not so drastic like this time. The funny thing is that it was overcast day without sun rays even peaking through the clouds. Just a giant soft-box, diffused light and I did not even expected a red to be blown out that way.
With K-5II I never run into this, nor with my old Nikon D300s... Too bad that I do not have Nikon or K-5II now just to compare how they are behave.
Maybe I should look for back-up body into Fuji or much better Sigma...
I could do a bracketed exposure but with flowers moving I do not think it is good idea, unless I do not have wind at all however fortunate me who lives 300m from Lake Ontario, there is always a breeze.
What was worried me is if the last update did something to it, as I did not had experienced this so drastic before. I guess this is just temporary paranoia...
That with IR filter might be a good idea as the sensors are more sensitive to broader spectrum but I was always thinking that each manufacturer placed proper filter into Bayer array and we do not have to play with additional filters here. My guess here is that Sony did not made good job on 24.3MPx sensors. Just wondering again how Fuji will behave in such condition as they have exact numbers for every channel (RGB) of pixels in one array. Sigma probably will be the best without any questioning here.
Will look further into and I might spend a money on Color Checker... or get a Sekonic lightmeter with color checker included.

Here are two screenshots where you will see that luminance adjustment in LR helped a lot but still...
Before any adjustments, everything on "0" After luminance adjustment only...
