Filter Size
Can anyone tell me the actual size of the filter thread for both 2" and 11/4 inch ep's?
The thread diameter is different to the outside measurement of the barrel of these ep's, being internal. I am wondering if it is a 'standard' filter size thread that was used for camera filters also. After all, there were some odd sizes back in the day, with twin lens reflex models, like the Mamiya, having varying size lens apertures and filter requirments for different lenses.
