A few very long zooms drop off in exposure just at the extreme telephoto end, which you can see -- but most of these are on video cameras and you probably wouldn't be using a light meter to set the exposure on a video camera anyway.
You will find though that many telephoto and zoom lenses don't open up as much as a prime, so if you had lit a scene to an f/2.8 and then put on a zoom that only opened to f/4.0, or a telephoto that only opened up to f/5.6, you'd have to adjust the light level. So when lighting a scene, thinking about the speeds of all the lenses you plan on using.

ahhhhhh.....David, Thank You. Now I can sleep tonight! Thanks for being so clear, concise and quick (response time). Makes sense.
That's David :-D I haven't been back here in a while and I forgot how much I like reading through threads and David's (as well as everyone else's, of course ) replies. I have learned a lot from this forum.
