Does anyone know if the size of millimetres has changed over the years or if Agfa weren't very good at measuring millimetres?
I recently bought an Agfa Super Solinette and the pdf manual (which I got from butkuss) says 'the diameter of the front lens mount is 30mm', so I bought a 30mm sky filter and 30mm lens hood and both are a little bit too big.
I tried a 28mm filter on the super solinette and it won't screw in. I think the thread pitch is too coarse, but I wouldn't know.
I've just bought an Agfa Ambi Silette and the manual says 'all lenses have the same 37mm outside diameter front cell'.
I tried a 37mm skylight filter and it's marginally too big.
And yet bothe Agfa UV filter and Agfa Yellow filter both have '37mm' on them. I should point out that the Yellow filter is a 'push-on' type.
Does anyone know the actual thread sizes I should be looking at?
Any help would be much appreciated.
