Hi When your'e using a zoom, the effective aperture shown in the CAMERA display/viewfinder is RIGHT - The aperture ring on the camera doesn't "know" how far you have zoomed. This occures when you use a zoom that does not have the same aperture all the way through the zoom range (like the 3.5-5.6): 3.5 at 28mm, and 5.6 at 80mm. When using non TTL-flash this is a small problem. That's one of the reasons, that zoom lenses with constant aperture often are prefered! Regards Jens

When my Pentax MZ-5n tells me I am at a given aperture, and the aperture ring on my zoom is on another aperture, which aperture am I really using ? The zoom is a Sigma 28-80 3.5-5.6 II Macro. I give an example : I set the aperture ring on 5.6, the LED tells me I am at 9.5 at 80mm, 8.0 at 50mm, 6.7 at 35mm and 5.6 at 28mm. The exposure time changes accordingly. - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
