wb problem Nikon d7000

GOLDENORFE

hi everyone , a friend has asked me to post these shots she has taken with d7000 , i use canon & have no idea , cant work out whats wrong!

D7000 with sigma 150-500mm all shot in fairly bright conditions
firmware updated this week made no difference.

these are not good shots, just to show colour problem!

she is getting a strong colour cast when shooting in bright sun! Blue in auto wb , and Green in cloudy! my canon cloudy wb just produces a slight warm brownish look, nothing like these.

shooting in raw colour is ok, as pic #1



but shooting in jpgs in auto wb images are quite "cold" blue cast. look fine in dull weather but in sun , very cold blueish cast
shoots jpgs in rapid bursts , raw buffer not big enough i think.
nikon say because not using nikon lens!!!! as they would! lol but is same with different lens's



shooting in cloudy, which should warm up the image produces a green cast



full bright sun produced this



shots taken in cloudy wb actually look better than in auto or sunny
any ideas ?
