To me it looks like the first three was out of the range of posible
aperures.

Emne: *ist D Metering Issue


I've put up four recent shots taken with the *ist D to demonstrate what I
had earlier mentioned regarding a perceived metering anomaly.

The first three are badly overexposed.  Exposure data is listed with the
photo.  All were taken within a 60 second time span.  All were taken with
multi-seg metering and Shutter Speed Priority AE mode.  Image one was shot
at the exposure values the camera calculated for a 1 sec exposure with no EV
compensation.  Realizing image 1 was overexposed, I adjusted EV -1.0 for
image 2, and EV -2.0 for image 3.  Not understanding the results I shot
image 4 at much different settings with no EV compensation and the image is
properly exposed.

Two basic issues:

1.  Why the gross overexposure at slow shutter speeds?
2.  Why was there not a visible difference between images 1,2,3 (especially
1 and 2) when using EV compensation?
