Here's my challenge: I recently bought a manual lenses badged by Sears--a very nice light 135/2.8 from the 80s, I believe. It's a fun little lens that I am hoping to get a lot of use from, but this is the first time I've used a manual lens (I have an A series zoom and some DA lenses). I'm using them on a K10D body.
I've done all that I know to do (from the research I've done on this forum)--set the custom menu to allow the aperture ring on the lens to be used, set the camera to M, set for center-weighted metering, used the green button to step down meter. All works great at 2.8--great exposure. I shift to 4.0--same thing. I move to 5.6--the correct shutter settings seems to register in the viewfinder, but it overexposes just a tad compared to the previous shots.
Then when I go to f8, it completely blows out the highlights--very overexposed.
Is there a reason for this that I'm unaware of? Do I have to step down meter only at the largest aperture (2.8)? Your help will be greatly appreciated.
