Thud and Blunder,
Thanks. I would presume so in ref to the 100-400. I think you can get them with and without vibration reduction? The following I took when I was starting out in low-level. These were all taken with the D70 fitted with the 100-400. You can get acceptable results with even cheaper kit and good practice. Even a 200mm lens at Cad Pass from the positon where I was standing would suffice.
