    127mm f4.7 Raptar and 135mm f4.7 Raptar: Do they both fit the same Rapax shutter

    Has anyone tried fitting the 127mm and 135mm Raptars into the same Rapax shutter.

    Just wondering if the threads on the 127mm and 135mm cells are the same diameter or different.

    I have a Rapax shutter for a 135mm f4.7 Raptar that isn't exactly "jammed", but won't cock...feels like something is in he way of the cocking lever. If I can't fix it, I may be looking for a replacement shutter.

    I have interchanged them and it worked... f settings seemed the same...

    The Rapax shutters are robust and respond well to cleaning and work well... Something is not resetting fully properly and probably gummed up, but will service well, if not damaged from forcing the controls...

    Proceed as normal...

    Rapax can usually be fixed with a CLA and they run a lot time after that.
