Hi I'm contemplating whether to sell my 70-200mm and get the 200mm. I like the zoom on the 70-200mm but I do encounter places where I wish I had a 2.8. The 70-200 1/2.8 is too heavy for me. On the other hand I am intrigued by reports of the shiokness of holding a canon telephoto prime L lens. I normally use telephotos for zoo, birdpark, concerts, portrait (minimal) and botanical gardens (with extension tubes)
