After getting some hands on time with the 7D before, my impressions going into Photo Plus with the 1D Mark IV were that it was basically a “grown up” version of that camera. In some ways I’m wrong, and in some ways I’m right. The 1D Mark IV is a camera that Canon users of all types and backgrounds will drool over. From the amazing high ISO photos to the lovely HD video modes, there is lots to love in this camera.
