re Purple flare:
I wonder how the HDR settings were set during the test. I have found that the flare character is completely different with the HDR setting off. What you have shown is consistent, in my experience, with HDR on. With HDR off you can expose correctly on the darker area with little flare or correctly on the bright end with a petal shaped flare.Using ProHDR, the flare is different again, but not entirely attractive either.
It may be worth examining this more thoroughly than I have and deciding whether to include it in an edit of the review.
And, for what it's worth, I think a review of one of the most widely used cameras is as valid a function of DPReview as reviewing a Leica M9, that only 4 real people can afford, and whom are unlikely to be affected in their decision by reading the site for its opinion....;-)
