does button have LOCK function for "bulb mode" or long exposures?

The button locks (in fact, some times by accident) but I haven't tried long exposure modes.

There is a lock function. Not 100% sure if it would be for what you need it for but I can confirm there is a lock function that allows photos to be taken continuously back to back until you take it off

Yes. But practice ahead of time so that you don't lock it accidently, and so you can unlock it easily.

Actually David if your shooting with a SLR you should have a bulb setting on your camera. In this mode you control the length of your exposure. The remote has a lock feature that will allow you to take long exposures.

No. If you are on bright, you can hold the button until it switches to red without going through the other light functions. Up youngish also switch back to bright by holding the button in.

Yes there is a AE-L/AF-L button you can access with your thumb. It has two wheels to change you F-stop and shutter speeds too.

On my camera I am able to choose "Bulb" setting which allows long exposures. Using my remote I activate the opening of the shutter, using it again closes the shutter. There is only one button on the remote. Remember to point the remote at the infrared receiver on the camera. On mine I had to point at the front of the camera.

Unfortunately, there is no button for that. But you can try the REVOLT, they do the light control button on the case.

There is a shutter-release lock around the edge of the release button which you can slide up to hold it in place for long exposure.

Yes, it does. As you can see in the picture, the button to the very left saying "LOCK" has a light bulb icon next to it. When clicked once, the button functions as a backlit button which illuminates the screen, but when the button is held down it locks the remotes setting so nothing gets changed accidentally.

I use bulb setting as well. This feature works best when you have a remote that is capable of being locked so you don't have to personally hold open the shutter for the duration of the shot.

That's a very vague question. Unlocking ISF Day and Night modes in the professional menu are the most flexible settings if you're a tweaker. Cnet's review has a calibration setting that you can try (I think it's in custom mode) as well. Enjoy!

Yes there is. Set the exposure dial to "P". This is the programed (automatic) mode.

I'm not quite sure what you mean by "lock". For me, I set the shutter speed on my camera (which does have a bulb option). When my camera shutter speed is on the bulb setting, I can press and hold the button on the remote for as long as I want to determine the duration of the shot. Does that help?

There's two buttons. The larger button is for the 3 light settings and the smaller button for the strobe. If you hold down the strobe button for more than three seconds it will stay on until you press the strobe or larger button again. Hope that helped!

It's the F5 button. There is no adjusting the brightness, however. It's just On or Off.

No, it just duplicates the functions on the shutter button. So, you can set the camera's exposure to "bulb", and use the remote to open and close your shutter (and if you shoot in mirror up mode you'll get even less jiggle), but you'll still have to watch a clock to determine when to release the button and close the shutter. I'm not aware of a remote with an integrated timer.

Yes. Set camera to bulb mode in manual exposure. Then you can set shutter time with the remote.

hold the button down for a second or two. it should cycle through light modes.
