Well folks, lets have some input and advice....

While out yesterday shooting a particular scene for our current tope event, I realized I have a problem. Is it a big one? Probably not, but still troubling.

I had my OM2n set up on tripod with my trusty 85/2 and was happily bracketing a few shots of an interesting scene when I decided, "hey, I'd like to get a few of these in B&W too. So I grabbed my trusty OM2 out of my bag and attached it to the tripod with the same lens at the same aperature focused on the same spot and found that meter was reading 2/3 of a stop higher.....ACKKKK I was horrified! I ran the series of shots again with that camera, figuring that if I bracketed the same way, at least one of the shots would be correct. Then I went back to my truck. I took out my gray blanket lined carhartt jacket and opened it up using the lining as a uniform place to take light readings and what do you know, with the film speed set at 100 and the lens at f5.6 and both cameras in AP mode, one suggested a shutter speed of 30 and one of almost 60. Using the compensation dial, I verified that there was indeed 2/3 of a stop difference between the two.

So, how do I know which is correct? It would be easy enough to compensate for this if I knew which was the bugger (or if both are off). This only needs to be temporary because as soon as I have a little extra cash, I am going to send the OM2 in for CLA. At this point I will know which camera is correct. IF the om2 was corect then the 2n will be following it to be serviced shortly after. If the 2n is correct, then the 2 will have been adjusted. but until that, how do I make do when I have no other trusted meter to compare them to?

You might see which camera reads closer to the Sunny 16 rule. You know, 1/ISO at F16 on a sunny, bright day.
