I want a state of the art AF system, with 4 fps and 25-28 MP.
The 5D was originally meant for portrait/wedding photographers and the 5DII added better noise control, video, somewhat better AF and a few more MP. But it is still a portrait/wedding photographer's camera. I want it to remain as such and do not want to pay for weather-proofing, dual card slots or 6-7 fps. Leave these specs for higher end cameras and give us a state-of-the-art AF system.
No dual card slots? I would think those would be great for wedding photographers. If one card goes bad, you didn't just lose hundreds of irreplaceable photos.
