I purchased a used 1D Mark IV, received it yesterday (Friday the 17th). Took it out for an hour for testing and messing around, came back and saw spots in my pics. Luckily I had an extra CPS coupon so I immediately boxed it up and it's on it's way to Jamesburg.
So my question is: being new to the Mark IV, are they prone to dirty sensors, kinda like the old 5D Classic, or is it just one of those things? By the way, the shutter count is approx. 9,300, but I am having Canon tell me that while it's there.
Thanks for all help...
