i bought a panny 20mm lens yesterday and havent stopped snapping away since, i think ive got a problem with it though

if i want to take a picture, i find i have to set it up in such a way that the light meter on my epl1 shows an over exposure of 1* where as if i try to take a picture with my original kit lens (14-42 oly) the image exposes correctly when the light meter says it will.


is it just a quirk of the panny lens?

*what is the correct terminology for what i am describing?

Is there a discrepancy between the live view and the image? Are you photographing a high key scene such as snow? Can you post an image.

BTW, you have not set exposure compensation by accident?

when i look at the lcd and the scene im picturing, it looks correct, its just when i take the shot, it always looks underexposed if i have set the shot as per the light meter, this is only an issue with the panny and not with the oly.

I think I'm right in saying that the image seen on the lcd is in fact a jpeg generated by the camera and is affected by the settings you have for the in camera jpeg. Are you comparing the lcd image with a raw file output from your camera?
You might find the following link of some help Settings for an Accurate Histogram

Perhaps try changing the metering

When I shoot with the 20mm on a G1 body, I usually use aperture priority but found the pictures (in jpeg) usually underexposed compared to what I saw on the viewfinder especially in low ambient lighting conditions. By switching the G1's metering to spot metering my pictures are now much closer to what I see in the viewfinder.
