    Do or do not. There is no try.

    Is an Ilex #3 shutter interchangeable with anything else?

    Other than another Ilex #3, of course!

    Umm, Alphax & Betax #3 seem to be the same. It is different to all of the European shutter sizes. It seems that the dial-set Ilex (the one SK GRimes describes as a piece of junk) is fractionally larger in the cell threads than the rim-set, but has the same size flange. The same is true of the #4 rim-set and dial-set.

    Bear in mind, of course, that the aperture scale may well not correspond with another set of cells...

    The Alphax/Betax #3 has a body length of 61/64" (~24mm) and a cell thread pitch of 40tpi. I've seen the Ilex #3 listed as closer to 26mm for body length and a cell thread pitch of 48 tpi so I do not think they are interchangable.

    Ah, didn't have the TPI information for the Alphax/Betax, only the diameter. So in essence all of the US made shutters are incompatible with products from other companies?
