The Canon EOS 1Ds Mark II’s overall design, features (fully loaded including E-TTL II), functions, build quality, image quality (not resolution of course) … are nearly identical to the Canon EOS 1D Mark II.

And for the most part, this is a good thing. Canon’s 1-Series digital bodies are weather-resistant (when paired with a weather-resistant lens) and rugged. They are made to hold up to considerable and demanding use and in bad conditions. Though rugged, they have an attractive, modern design. Although some may disagree, I find the Canon 1-Series body very ergonomical. Although not light, the tactile feel and balance are excellent. The Canon EOS 1Ds Mark II feels great in my hand. I find that some setting changes are not as intuitive and logical as I would prefer, but I have definitely acclimated to the functionality.
