I own the 70-200 f4 L I bought a 1.4 Extender with it and used that combo from day one. Even at 5.6 I could sharpen
the pics in DPP or PS and be happy with the end result. I bought a 2X Extender because I wanted more reach. Hand held
the images were softer than I liked. Mounted on a tripod and using LIve view and manual focusing produced an image that I could sharpen in PS and print. I was happy with the results. I decided to buy a 100-400 L. It's a Heavy Beast.
I am getting used to the weight and am quite happy with the results. I got a pic of a Black Bear that was eating apples
off a branch that it had broken off the tree. I haven't printed it yet but am sure I will be happy with the final print as the
jpeg that I emailed to friends looks great. I don't go on long walks but if I did it would be with the 70-200 F4 IS USM L with the 1.4 Extender and my 17-85 IS lens. Good Luck in your decision.
