Well, as long as you are using an aperture smaller than 3.8 (in this case) say f4 or smaller, you won't have a problem using an external meter. If you are trying to shoot at full aperture, you may be forced to compensate a bit. For example, if you set the aperture at f/8, it will remain at f/8 throughout the zoom range.

If one uses an external lightmeter when using a variable aperture zoom lens will you have a problem, for example with a 35-80mm F/2.8- 3.8. As I understand this zoom it is F 2.8 at 35mm and 3.8 at 80mm most of the time one is not on these end aperture's. I assume in-between 35mm and 80mm the aperture varies between F 2.8-3.8 How specifically does one take a proper light reading with an external lightmeter using a variable aperture zoom lens. thanks in advance Denny B - This message is from the Pentax-Discuss Mail List.
