Skatol, that might work. Shots showing parts of bodies!
I sometimes think about this when heading out with my usual 300 X2. I've had more regrets with 300 X1.4 though. Now, when there is a pretty good chance I can get seriously close I tend to want the 300, but that's rare.
Always seems there isn't enough time to be swapping lenses!
I did get the 2X off just before I lost my woodpecker so I've this one decent shot.
