[QUOTE="Mike D90, post: 294247, member: 17556"] Well, I was under the impression that the Sunny 16 rule (f/16, 1/100th sec, ISO 100) was for a given focal length lens. If you zoom any lens out then the exposure values change, i.e. need more light than at shorter focal lengths. I am not saying it wouldn't work but it would underexpose at 200mm versus a shorter focal length. I think . . . . will admit I am a little confused as to how this works. [/QUOTE]
