Faulty 645 120 FA Macro Lens?
Hi,
I have just purchased a used 645 120 FA Macro, and it seems the lever at the back that opens the aperture is flopping around, whereas with all of my other lenses it has a spring release. For instance just by rotating the lens the lever moves under the effects of gravity, swaps positions and opens/closes the aperture. Would someone else with this lens be kind enough to confirm whether this is behaviour is normal, or that it is not and the lever is spring loaded?
Thanks,
Andy.
