I am using a PD prism that seems to the metering is off by about 2 -3 stops from where it should be. I am using ISO400 film in very bright Florida sunlight. The meter is giving me a reading of f/5.6 at 1/1000 sec. Using the Sunny 16 rule, as well as a DSLR, I should be around f/11 @ 1/1000 second. I have checked the battery indicator and it shows that the battery is still good. I have the shutter speed dial set to the little red dot inside the circle.
The lens metering tab is properly engaged with the prong.
Any thoughts as to what might be causing the problem?
Edit: I think I just found the answer. I had the DOF AM lever on the lens set to M instead of A. After switching to A I got the meter gave me the correct exposure.
This little issue at least confirms that I am starting to get the hang of estimating exposure without using a meter. I knew, from Sunny 16, that f/5.6 @1/1000 second would have way overexposed the image. My little confidence booster for the day!
