    Re: Ideas for new shutters 40 years from now when ours are all dead

    I like the odds of well-maintained, simple mechanical leaf shutters working 40 years from now and long after. My own parochial view encompasses only Alphax and Betax shutters, and earlier this year I serviced a few large Betax shutters from 1923. There was nothing wrong that a simple CLA couldn’t fix, and I couldn’t see anything to stop these shutters from working for decades into the future.

    Alphax shutters have an even simpler mechanism and improved materials. The stamped metal parts are quite durable, springs can be fabricated if necessary, and spare parts are common for these shutters mass-produced over five decades. While I’d warmly welcome new shutters arriving on the market, I’m confident that the well-made tools of the past will continue to serve us far into the future.

    The problem with the no-moving parts shutters are plenty. Total dark is an issue, not easy (or economically possible) to achieve with LCD or optical cell technology. You lose 1-2 stops by inserting those and they are driven by electronics with a shorter lifetime than mechanical shutters.

    Yes, I play with the things I just described.

    It should be more than obvious that Randy was talking about Copal/Compur/etc. mechanical shutters.

    I highly doubt modern Copal shutters will be a problem in my lifetime, and I'm much younger than most of you.
    Not at all obvious. He obviously does not know about them!

    My modest accommodation for dealing with inaccurate shutters is to find one or two speeds that match my light meter readings. Stick to those and use f-stops that work or filters that make it work. I use a few large shutters and without such measures none of them work properly. So you could claim that I work backwards from what works, regardless of the shutter dial.

    Nor does anyone else, and I see nothing on Linhof Studio's (terrible) webpage, and my Google searches bring up nothing about 4x5 or larger cameras using anything like it. Not sure what the point of bringing up an arcane, basically unused shutter is when discussing the lifetime of mechanical shutters when likely no one has or will use one, but okay.

    Just teasing you a bit, Jim. You better start shooting that film or someone in the future will waste it on selfies, pictures of their dinner, vacation shots of their toes in the sand or worse........cat pictures!

    Couldn't find it on their awful site. No information is even given. Is ANYONE here using these for actual LF?

    Yes, as long as a 3 size shutter isnít required. Why else do you think that Rodenstock, Schneider, Linhof and others sold them?

    Are you saying you own and use them for LF photography?
