Yes it is, if you're actually changing the aperture and not keeping it on F1.8. Otherwise the camera assumes the lens is wide-open.

Green button is a good starting point if you donīt know what the settings should be approximately.. Then fire and chimp, adjust and good to go

I donīt understand...

When I put my M 35/2 on f8, and press the green button - the camera stops down and adjust the time so I get a (generally) well-exposed picture.

So, it stops down, meters and sets the time.


But are you saying something else?

You are using the green button correctly. If you don't then the camera will assume the lens is wide-open no matter what aperture you've set. This applies to the K & M (fully manual) lenses.
