Question: Does this remote release have the ability to do timed shots (i.e. if I want to take 30 second exposures for a duration of 2 hours)?
Document: I bought this Nikon unit for my D90 (it also works on the D3100) after the Zeikos remote unit failed. Although the Nikon unit is a few more dollars, I am very happy with the purchase.My main reason for purchasing the unit was not only to get a sharper shot from a tripod (less vibration than pushing the shutter release manually), but I wanted very long exposures for night shots. These exposures of 30 minutes or even 6 hours, are not capable without the remote shutter release.
i shoot landscapes primarily and this is invaluable. It allows me to keep the camera steady when shooting at low shutter speeds. i usually compose the shot and set focus lock and then use this remote to take the picture. i also use it when i have bracketing turned on because i have to take a number of shots and i don't want the camera to shake during the different exposures.
This is exactly what I needed to take long exposures on my D7000. It is also very useful in taking close up photos or any situation when you want to keep your hand off the shutter release button.
I can now take pictures with long exposures without touching the shutter release button. I now take great night shots
I bought this unit to take long exposure photographs helding my camera still on a tripod. It will only work on bulb mode. You do not need to have the MC-DC2 shutter pressed all the time, just push it to hold mode, and go get beer and come back when you want (for as long as 30 min max I guess) and push it back, and you are set.
Really like the remote but it doesn't hold a stick to my old Nikon CoolPix remote. This remote only triggers the shutter. Conversely, the CoolPix remote allowed for zoom control and timed shutter release for time lapse, but it costs over 5X the price of this remote. I bought it for my Nikon D3100 and it works perfectly. I await for Nikon to release a more feature robust remote, but in the meantime this will suffice. If you just want a simple remote shutter release than this remote is for you.
And darned well should considering it is the OEM's version of the remote cable release. This is an absolute necessity for anyone doing exposures longer than 1/30th of a second on a tripod or any type of long exposure. This is also essential when doing macro-photography on a tripod with available light or with F stops over F22.
Great remote trigger for D90.A must have for those who like to shoot low shutter speeds on a tripod.I do pano 360 photos and this is so much better than using the 2 second timer functionto avoid any camera shake.Construction is good and feels very durable.
With the ML-L3, sometimes I find I'm not in the right position and I have to press it multiple times. And if I don't get it in time, the camera will stop seeking the remote and I'll have to go back to it to get the remote to work again.The MC-DC2 also has a sliding latch that will lock the shutter release in place for when you want to do longer exposures (set the camera to bulb).
Its works great, but I wish I had shopped around for a wireless remote release cord as this is useless if you want to take group portraits with yourself included without having to use the timer. I was foolish to think that this is the only cord available. The 1 meter  (about 3 feet) is too short.
Answer: This remote does have a switch that you can move to a locked position which will keep your camera shutter open until you unlock the switch. That time could be as long as you want the shutter to remain open, however it does not have the capability to do what you are asking. Some DSLRs do have an automatic interval timer feature built in, like the Nikon D7100. Check your camera manual.
