Which leads to another question: When using a lens with such an 'automatic' tube on a 67II with the AE prism and using the "A" setting (automatic exposure). Do you need to stop down the lens manually before taking the picture ? Or is the actual measurement of exposure done AFTER the lens aperture is closed down but BEFORE the mirror goes UP ??? Anyone know ? I will try to experiment a bit with that, but it probably takes real test-exposures to tell for sure ...
