Testing the Canon 70dD and Canon 70-300mm F4-F5.6 IS USM lens

A video to demonstrate the hybrid (contrast and Phase detection) auto focus system on the canon 70D with a IS USM lens like the 70 -300mm. Showing how accurate the focus is, how fast it can track motion and how smooth focus pulls are.
As this is an EF mount lens I also shot some images with a full frame Canon 5D MKIII camera for comparison.
More of the test results including sharpness at my photographic blog.
