Which Camcorder will be best for super zoom and Blog?

Here's the problem. You say you want a SLR, but none of the cameras you list in your post are SLR cameras. Also, SLR cameras do not have digital zoom. Finally, 20x digital zoom cameras do not exist because that much digital zoom would result in a completely unusable picture. Please stop posting this nonsense question and read a couple books about digital cameras. At least then you can ask an intelligent question that can be properly answered.
