So it doesn't handle as nice as the 1Ds that it replaces, and the most inconvenient aspect of it, the split screen is not available for the 5D. It does come with a grid screen but I find it even more distracting than the plain old stock screen. I probably will consider buying the EE-S screen to aid manual focus.
It's great to have full frame again. This camera with the Holy Trinity (35L, 50L & 85L) are unbeatable. Hopefully I will use the heck out of this camera, like I have with the Panasonic G1, which is now over 12,000 frames.
