Well, kind of...
Whenever driving on non-interstate roads in the West, I always have the longest lens I have with me attached to a camera which is ready to pick up and shoot any wildlife that I see. My rationale is that if I need a shorter lens, I will have time to switch lenses but, if I need the longer lens for an animal; I won't have time to switch.
I recommend this to anyone who is vacationing in the West.
I was driving today in Yosemite National Park, California and I did have my 70-200mm f/4L IS lens attached to one of my cameras UNTIL I CAME UP TO A BEAUTIFUL MEADOW with a pond in the foreground. I did have time to switch to a shorter lens.
I switched to a 12-24mm f/4 Tokina on my 40D and had a 24-70mm f/2.8L on my 30D. These were great focal lengths for the meadows shots but....
A black bear came wandering out into the meadow with her two cubs and they all went for a swim. Naturally, the 70-200mm was back in my vehicle. I certainly didn't want to intrude on that happy family by getting close enough to use my 24-70L and by the time I got back to the car, she and her cubs had wandered off.
