AgreedI believe a 1D4 is better value for money than a 5DIII - especially if you can get a use one.The 1D4 is not even FF.
Different type of camera but if you want a sports camera with top IQ then it is still the current top of the pile
So what? The image that comes from it is top rate. 10 fps, top AF, metering at the AF point, AF for f/8 lens, good high ISO images plus all those nice series 1 functions (like manual settings plus exposure control). 5DIII doesn't come near it for sports/birds/wildlife.
