[QUOTE="Mike D90, post: 294255, member: 17556"] Hmmmm, then I guess that makes me question why a zoom lens doesn't have the ability to use its widest aperture then? If its exposure is the same at any focal length then why wouldn't a 70-300mm zoom also use its widest aperture at 300mm? Or am I just too confused to see the workings here and a zoom lens works the same (as to exposure) at any aperture [I]ABOVE[/I] its minimum for any given zoom length? [/QUOTE]
