Hello, all. I've had a lot of metering problems with an AE-1 I bought recently. I've never had this with any camera of age purchased before. It seems to be extremely sensitive to really light or dark areas. I know that this happens when metering areas that are far from grey, but the camera seems to adjust sometimes 2 or 3 stops in either direction versus a neutral colored area. It also treats items in brilliant sunlight as close to white in its calculation.

Furthermore, I've tried using a 100mm macro lens with it, and anytime it's at full extension, the meter underexposes by several stops. I've had some disappointing results, so I'm just wondering...is the center weighted meter extremely sensitive to changes in brightness and can't deal with long lenses, or do you think I just got a lemon?
