Thanks you for the theme! What is the Apsc multiplier? I shoot micro 4/3 so my 60mm is 120mm. I generally shoot speeds of 1/60 to 1/250. Your correct though the longer the focal length the more camera shake. I will have at least 20 throw aways for every good shot. A good tip i use is to focus with the lcd and i use my camera strap on my neck as tension to stabilize the camera.
