    A no shake mechanical Cable release?

    On the weekend I tried a couple of 1 second exposures with my K-O and found that a few shots suffered from camera shake. I had the camera mounted on a decent tripod, using a standard run of the mill cable release, which was a bit too short. I am pretty sure that the issue I was experiencing was due to the force required to actuate the shutter causing the shake.

    Since I am in the market for a decent cable, what can people recommend as a decent mechanical shutter release? Should I simply go for a bulb type air actuator (cheap, cheery and simple), or is there other types people would recommend?

    Cheers

    While you were there and know best, I tend to think that the cable release would not be the source of the shaking -- if you kept some slack in the cable and did not have it pulled tight. The amount of force needed for the piston of the cable to trip the shutter will probably be the same no matter what type of cable you use.

    I do not know what a "K-O" is, but if it is a single lens reflex type of camera, you might be getting vibration due to the mirror, if it has one. I know from experience that such cameras as the OM1 need to have the mirror locked up on long exposures -- a light-weight camera and a strong mirror action.

    At least with LF landscape, a bad day of photography can still be a good day of exercise.

    the air bulb would be quite a good idea, or, if your camera has a timer, set it upon the timer and let it fire for 1 sec. But if you're manually timing 1 second try an air release one, they are a lot smoother than the cabled one

    a deGroff air release will solve any release related vibration issues. Your Koni Omega doesn't have a mirror, so doubtful that the problem lies there.

    I agree with Vaughn, especially with mirror slap. Most modern SLR cameras have some sort of mirror damping system, but even that doesn't completely eliminate the vibration, mirror lock-up is the most effective means to that end.

    I'll 2nd (3rd) the air release idea. There's absolutely no chance of shake, whereas with a mechanical release you're still directly coupled to the camera. Even if there's slack, the slack acts like a leaf spring and pushes against the camera... at least in my experience.

    for those that have never seen a Koni Omega,


    it's a rangefinder focused, medium format modular camera system.

    Ahhh...so that is what a K-O is! I used a similar camera, a Mamiya Press Super 23, last year in Yosemite...great cameras!

    So I will agree that an air release might help out. I am still surprised that operating a standard cable release causes problems, but an air release is smoother.

    I agree with Vaughn.

    Two points particular to Koni-Omegas:

    1) the cable shutter release requires a long throw and a fairly high amount of pressure. For that reason, a longer cable release, with a long loop and lots of slack is necessary; and

    2) the Koni-Omega's release is on the front of the body, and unlike most 35mm cameras requires a push straight back. When the camera is on a tripod, actuating the release will have a tendency to twist the camera slightly. Some tripods are much less effective at resisting that twist.

    Thanks all,

    And to why was I getting shake? Its exactly as Matt suggested. The cable that I had was way to short, so it was easy to actually physically rock the camera while holding onto the release (I saw myself do it!). I just thought that since I needed to get a longer release, I might as well try and get something that works properly in the first place (thinking of future cameras!)

    Cheers
