Being able to attach a filter may come in handy. It's surprising as to how short the exposures can be when the sun's out. My Noon 612 has a f/250 aperture and there are times I could use a ND filter, even with Pan F.The whole circle piece at the front twists to open and shut the shutter, yep spot on the front is threaded to accept a filter
