    copal vs. electronic shutter

    I need some clarification on the matter of shutters.

    A standard Copal mechanical shutter goes from 1s to 1/400. I frequently expose in the 2 to 4 seconds frame so I guess I would have to use B and time it myself?

    The Schneider electronic shutter goes down to 30 seconds but the fastest shutter speed is 1/60. Is this really true? So, you must control the light with lots of ND filters or how do you work in practise with such a slow (top) shutter speed?

    The Rollei electronic states long exposeres and reasonable 1/500 too. This would be ok with me. But here I see many Schneiders not being offered with the Rollei.

    What is your take on this? What's to prefer?

    I also suppose that you must connect the lens to the back via the flash sync, atleast with the mechanical Copals, so where do you then connect the flash cable when in the studio?

    latest compurs do 1/500 , but yes - once you past 1s - you on your own for long exposures. B and iPhone

    But here I see many Schneiders not being offered with the Rollei.
    You can always mix and match, if you ok with remounting lenses.
    As long as thickness is same you ok. Just have to hunt shutters down.. Or buy new ones.

    You connect lens sync to back and back got its own sync outlet for flash.
    Got to remember to switch shutter from M to X, if there is such switch. And may want to buy at least one bi-post to regular pc syc adapter, if plan to deal with old american made shutters like ACME (which are, by the way are GREAT)

    Thanks for your reply

    How do you handle the slow shutterspeed of 1/60 in normal/bright light? Are you using ND filters?

    hm? Why would it be a problem? Most of mechanical shutters do full stops all the way from 1s to about 1/200-1/500 quite fine nowdays. Few old huge ones do have 1/60 top , but you do have iso control (drop it down to iso 25-50 and you golden with f32-f16 even on 1/60) and aprerture control.

    250$ will buy you new Compur shutter in size 0 or 1 , that you can sync with flash and go wild. Many places do sell them...

    Reminds me - i need to send emails to folks at lens2shutter , so i can start mounting process for couple of old brass lenses i have.

    Re: copal vs. electronic shutter

    I am going to go for copal shutters. I suppose timing a few seconds yourself with B is just a question of getting used to. And with 1/500 shutter speed I am absolutely fine.
    The bonus is one less gadget (electronic controller), one less cable and one less battery to charge.

    Thanks again fo ryour input

    The Sinar eShutters should be available now, and they do 1/250th.

    It helps to have a camera with low base ISO.

    ΏAnybody using Sinar eShutters?

    Re: copal vs. electronic shutter

    Very few people use electronic shutters outside the studio as they require additional cables, batteries and controllers.
    In the studio, the plus is being able to control them from the computer and have small aperture/ shutter speed adjustment increments (in Rollei's case 1/10th stop increments)

    re Sinar/ Rodenstock e-Shutters AFAIK they are not shipping yet. Last I've heard was end of May for 1st demo batch

    what is ridiculous is that there are perfectly accurate & fully developed & auto cocking & reliable & very quiet, electronic shutters, as built into wonderful lenses like the Mamiya 7 ones, but... they are not available for MF users.

    If only we could get those on the Schneider or Rodenstock lenses, it would make MF digital life a lot easier. Phase - don't you own Mamiya?

    Problem, problems...

    I would really like to avoid having to buy 2 sets of lenses, or change shutters regularly, but I will need or appreciate electronic shutters for many applications:

    Multi-flash for layering with hand-held flashes and remote camera and flash operation for architecture etc. where I need movements.
