I wonder if you guys can give me some help regarding using older manual lenses on the GF1?
QUESTION 1.
I have a Canon FD50mm f1.4 lens with an adapter for the GF1. All fits and works fine.
On the adapter ring is a ring with an arrow pointing in each direction saying <lock/open>
I assumed this was to lock the adapter on the lens/body.
When I turn the aperture ring on the lens to F1.4 I get a nice shallow dof and when I turn it to F22 I get a wide dof, so far so good! Using Aperture priority the camera sets the shutter speed.. great.
TheN I noticed that when the lens was set at F22 and the ring on the adapter (lock/open) was turned, the lcd view went darker and the shutterspeed changed and the aperture was changing. (Actually it wasnt uniformly darker, as it was turned it went darker and lighter until settling at dark at the end of the turn of the ring) When the lens was set to f1.4 and the same thing with the lock/open was done, nothing changed.
Should I be using the aperture ring, the lock/open, both or none??
Do others have these things and are they normal?
QUESTION 2!!
I have a Canon EOS adapter for the GF1 also.
As the EF lenses don't have aperture rings on.. how do you go about changing aperture on these or do you not?
