Nate,
Yikes! Bad news! Indeed the dreaded green cast is there.
I rarely use the presets. Usually I white balance with a card to get the advantage of shooting in real prevailing conditions
rather than the presets.
Hmmm now I have to decide whether I want to send the camera out for the fix or live with it.
I’ll think it over.
Actually I usually shoot a tad warmer outside, about 4900K, makes those skies just little bluer than 5600.
Other than that I love this camera, with the caveat of having invested in really good glass. My lens costs almost twice as much as the camera itself. But it’s worth it.
Good luck w/your 500.
Best,
Paul
