Wow guys, extremely helpful.. I wont trust my internal meter much if this is the case. I didn't even think how it could be out of calibration.
I bought this light meter from B&H

it's a ambient incident and reflected light meter. Will this work, or should I pick up the spot meter?
David, thanks for the post... I hope eventually my films will come out as nicely as yours. As I stated before, I only shot 64T in the past. It left a lot to be desired. I think the 500T and 100D will be my two weapons of choice.
I just want to be sure on the workflow (to mirror your results). After taking my readings with the light meter. adjust my aperture to 1/2 to full stop over my given reading for 500T; 1/2 stop under my given reading for 100D...?
I'll pick up an 85 filter from B&H... When I'm using the filter, I guess I would adjust my light meter to 320iso (cant remember the exact number) to reflect the install of the filter, right?
The newb,
Steve
