Originally posted by montman Thanks Jonathan! This was my second roll of film, my first one came out really underexposed. I had to rate this at ISO100 and even then overexpose with the metering. I don't know if my camera meter is bad or it's just the characteristic of the film?
As Aurele has said, check the meter.
Either the meter is wrong or the shutter speeds are slower than they should be. This can happen with age and I imagine a CLA would fix it. I recently took a just-bought KX into my local camera shop just to change the seals, it took them 30 seconds to run a quick check and tell me that the shutter speeds were slow. I don't know how they did it, but I ended up having a full CLA instead of just the seals. That way I don't have to worry about it.
