Hi Art! I did as you suggest, when I duplicated Bob's test, earlier today. When the exposure was correct, I got grey for the white.. indicating the metering was right on. However, as I stopped down, metering at each step... er stop.. the images got consistently darker. As the shutter speed changed with the different stops, the end photos should all have been the same shade of grey... but that didn't happen. More curious is that, to me, this would indicate under exposure, yet Bob is complaining of over exposure. What I do know, is that in non-test conditions, I've never had a problem with the Canon's metering... but then I mostly use it at f4 through f8 - nothing smaller. Cheers! David. ------------------------------------- On 31/07/2005 at 10:22 PM NATSTEK@xxxxxxx wrote: Guy's, I started out with my R7 doing the same thing when I used a bellows II & viso heads with the 14167 adapter. Make sure that you're in aperture priority AE and focus wide open, then stop down to the taking aperture and look at the display in the finder just to make sure that all is OK. you still must realize that the meters still consider everything as 18% gray, so you may have to dial in some exposure compensation.
