#40. "RE: Bob, did you re-shoot that bolt?" In response to In response to 39 Fri 01-Feb-13 01:59 AM by Lunastar
The best advice I've seen here is Neil's suggestion that you take the rig outside and shoot and test it there. If it's cool outside and warm in you'll definitely get the "mirage" effect from the warm air hitting the cold. Also, I see you have both the 70-200 and 200-400. If you are a bit concerned about the 600 take those other two as they will both get a lot of work at Yellowstone. Matter of fact, a mobile photog friend of mine shot exclusively with a 70-200 there last March and came back with many great images. Good luck!
