Good story, but rather drastic. You might hurt the bike.

Yeah. Weird, huh? Batteries seem okay. Could it be the lens?

Don't know, very odd that all 3 are off by the same number of stops. I think the light meter sensor is in the body not the in the mirror prism box. But again don't know for sure. Are the batteries fresh?

Batteries came with the cameras. I'll try with fresh batteries anyway.

Did a test just now against a white fence in my backyard under constant light. F100 and Olympus E-520 give 1/8 @ f/16. The three cameras give 1 sec, 1/2 and 1/3. All set at ISO 100.

Fresh batteries and no change. I don't get it...

Could the lens contribute to giving bad meter values? And if so, is there a way to test the meter without it (I only have one SA mount lens)?

Sorry no idea, just very strange, not many Sigma SA users so not a lot of info to draw on and as I dumbed my SA bodies. I just metered my SD 14 with both the 28 to 80 and 28 to 100, ISO 100 set at 50mm, quarter stop between them.
