Automate the Shutter button

Gentlemen,

My camera doesn't have a delayed shutter timer, technically is does but I have to hold the button down for up to 30 seconds, so I thought that I would replace my finger with an automated device but I have no idea what the thread is in the middle of my shutter button, can anybody help please.

For a mechanical. shutter release.

Bill

sorry forgot that bit, I want to fit a solenoid which is controlled by a timer which can be set to work up to the camera's max of 30 seconds.

Martin P

I would buy a cable release which has the correct thread form already then fit your solonoid on the end of that and decouples any vibration from your camera when the solonoid actuates

The thread is a tapered one ( i assume you knew that )

Sorry Martin, I'm a little confused.

Is it the self timer for delayed exposures or is it the 'B' setting for long exposures?

If the self timer, it sounds like it is broken

For the latter I have a cable release with a locking screw, press in, lock the screw and leave for as long as you want.

Yuo can control the exposure time with a black hat over the lens.

Neil,

Everything works ok, the problem is the idiot operating the camera, I have this problem when using the button or a cable in that I snatch and cause a shake particularly when using the B function which requires me to hold the button pressed for the time required up to a max of 30 seconds so I thought I could make a device to do it for me.

I have seen clockwork timers on ebay to fit cameras. Have a look. Which camera do you have?

Clive

Martin,

just get a locking cable release, and hold it so there's a reasonable bend in it - that way you won't snatch.

Neil

Neil,

Found the answer, went onto Amazon to get what you suggested and found a switch with cable which plugs into the mini USB on my camera which operates the trigger electronically and it also has a lock for the B function so no more snatching of cables or buttons.
