RE: metering issues.
I have started using a few alt lenses, and heres the problem with AV.
you can NOT match the F# used, with the F# on the camera.
The camera is assuming (and rightly so) that the light falling on the sensor during mirror down metering is, at full aperture.
SO if you have an F1.0 lens, and open it up to f1.0 and set the camera to F1.0. it will adjust the shutter speed correctly.
HOWEVER, if you set the lens at F4.0, and set the camera, at F4.0, the camera is going to see the amount of light @ f4.0 and meter for that, THEN subtract, 4 stops.
this will be a devastating over exposure.
If you want do that that either a: leave it at F1.0 and set the lens at f4 and ignore the "falacy" or b: set the lens at f1, meter @ f1.0, then using manual or AE lock, hold it at that setting, then change it to F4, and stop down the lens to F4.

Wrongo... Using stop-down metering when using 'dumb' mounted lenses is the way to go and usually requires very little EC.

Canon cameras all display f0, no matter what stop you set the samyang lens at. with the Samyang 14mm lens, I place my camera in Av, focus, then stop the lens down, and press the shutter button to meter the light at f4 and open the shutter. It does meter about 1/3-1/2 stop too brightly, but not 4 stops over.
I was having a problem with my 1D MK II overexposing, however, a full camera reset fixed that.
Exactly!
