My 50mm f1.9 Yashinon doesn't stop down when adapted to my Olympus Pen -F with a Fotasy m42to M4/3 adapter. The lens has no Auto/Manual switch. Is there an adapter that enables aperture change?
Thanks
Kurt Ingham

make sure your adapter have that plate to hold the aperture lever (or something) because all of m42 has it, and some lenses has a auto manual switch just like you've said...
or if you're brave enugh you can modified the lens and add somthing to the aperture mechanism so you could change the iris size without any external holder...

The adapter is old, and it doesn't have that. Do you know any brand that will have one for sure"
