I have found that the colour of bluebells seems to be difficult for (some?) digital cameras to capture accurately. It looks as though the A7RII makes a good job of it. Beautiful lighting in your photo, too!
I just bought an A7 with kit lens, new. At those prices now a day I just couldn't refuse. If it stays, who knows. Will it make me forget my Fuji X-Pro1, don't think so . . .
But it's small and that's what I like and it's full frame and that's what I wanted to try, and it's weather sealed and we have a heat wave . . . .
