Bob, I think if you'll check - using bulb setting, that the aperture will stop down at time of shoot with a tube on - just not the metering. So yes, you have to stop down for metering, but not to shoot. Just pre-meter the area you are shooting and you'll be all set.

It means I'll be using a tripod for anything I do 6x7 macro. Butterflies are problematic! Rac> Regards, Bob S.
