I have hardly used video on my D7000 and I'm not a videographer, so don't blame me if this is a known effect :-)
Just been viewing some video shot with a friends C*non and have noticed something that I never expected to see... It was hand held, very low light (a tornado and storm was going past about half a mile away) and on the C*non, as we (wobbly, hand-held) moved the camera, just in small increments to follow the action, the sky moved at a different speed to the almost completely in shade land. They were moving independently in a series of small 'jerks', can clearly see them moving at different rates as I moved the camera.
This can't be normal for a $1500 dSLR, can it?
If so, then this is junk!
I am sure we could get better from my Dad's 40 year old super 8 film camera!!!!!
If anyone wants to see it, where best to post a 5Mb movie file to?
