Fotasy 100cm Mechanical Cable Shutter Release with Bulb-Lock for Fujifilm X10 X20 X30 X100s X100t X-Pro1 X-Pro2 X-E1 X-E2, Leica M6 M7 M8 and Nikon Df F4 FM2 F3 FE FM3a F80, Threaded Release Cable

This product broke the first time I used It.

There seems to be a lot of people who think this cable doesn't work and a few others who don't really know how to take advantage of its versatility.I worked in a camera store back in the '70's, (when such a thing existed in nearly every city and town), and I am familiar with this item as it remains unchanged all these decades later.It is all about the knurled ring under the plunger. When you push the knurled ring down and turn it clockwise to lock it down, the cable release is free to trigger an exposure and the plunger will return to its original position and pressure will come off the inner exposure button on your camera. When the knurled ring is in its upper position, or you turn it counter-clockwise to unlock so it is in its upper position, the cable release then becomes a LOCKING cable release. When you press the plunger down, it will lock in that position until you press down on the knurled ring to release it from its locked position.This is a mystery to digital camera owners.In film cameras, which have adjustable shutter speeds, there is sometimes a speed marked B for Bulb Exposure, With this setting, the shutter simply stays open as long as the shutter button remains depressed. It is preferable to use a cable release to prevent camera vibration during the longer exposure. This allows you to take pictures like the one I attached, which shows me looking south on I-95 and a jet is crossing over the highway from right to left. The exposure was 15 seconds, so the headlights and taillights are ribbons of light and the blinking lights of the landing jet are short beams crossing in front of me.In short, this is a great cable release and it works perfect when you know how to use it. Happy shooting!

It works and it's easy to use. The microfiber cloth it comes with was unnecessary but it's a nice touch.It's a little short, so when walking around with the camera+tripod, it dangles in a way that makes me nervous about it damaging the shutter. If it was a little longer it might be easier to wind up or secure it.I haven't used a shutter cable before so I have nothing to compare it to.

It works in locking mode (need to press on the knurled disc to release). This is how I'm planning to use this cable release, for long exposures in bulb with a film camera where I don't want to hold the release. I tried unscrewing it to release immediately, but it makes it wobbly. It seems fine for occasional use, but I wouldn't depend on it, it does fell like it costs $8.
