Hello all! I've recently obtained a new toy - Pentax MX camera and have only played with it for a while (didn't run a film through it yet). But I've noticed a problem with metering - I measure the ligh from a same scene while changing the aperture and shutter. For: f/2.8 1/30, f/4 1/15, f/5.6 1/8 and f/8 1/4s combinations I get correct exposition reading (green LED lights up) but when I change the shutter speed to 1/2 or 1s the bottom red LED allways lights up. This is when ISO 400 is set. When I change ISO speed to 200 I get correct reading for 1/2s and wrong one for 1s and for ISO100 the situasion is correct for 1s, too. When going in other direction the situation changes other way: problem shows up on 1/4 for ISO800 and 1/8 for ISO1600. I've tried changing batteries with no effect. Also changing the lens form A 50/1.7 to A 135/2,8 or FA 35-80/4-5.6 didn't help. What may cause such a problem? Is it possible to fix it by myself? I don't use those shutter speeds anyway because I don't have a good tripod but it still bothers me a lot. Is sending a camera to e service shop an only option? TIA for your help.
