Hello friends, I bought a Canon A1 some time ago and been shooting with it for a while, using sunny 16 technique because I didn't trusted the lightmeter. I would like to hear from you whats probably causing this anomally. Indoors, even with light, pointing directly at a lamp, the fstop meter is no more than 8, maybe 11. Usually, outside the house, on a sunny day, at a speed of 1/500, the camera tells me to always shoot from 2 to 5.6. It turns out that the first time I tested a film with her, I followed her advice and ended up with an entire film overexposed. So, you see, it seems a little off. Didn't tried, although, shooting a film setting it up to P in shutter priority to test the "balance" proposed by the meter. what can be causing this? already tried new battery.
