Provides a directly wired control of the shutter, as well as a programmable intervalometer. Few tests I have done so far indicate that it works well as specified. Instructions were poorly translated into English, but after reading them 3 or 4 tiimes with the unit attached to the camera, managed to get it to work well. Battery cover is loosely fitted and has to be held in place with a piece of scotch tape.

Switched to Sony from canon and had the exact same intervalometer for my canon, and this one is even better! Doesn't have an on off switch but the batteries last for everrrr. So useful and works perfectly.

This is a fantastic little shutter release. The main reason I purchased this was the intervallometer function and extra long exposure times. My camera, the Sony SLT-A58, has no built-in interval system, and has limited exposure times of 30 seconds. I have shot several long exposure star timelapses with great results. I also like that you do not even need batteries to use the shutter release function; simply plug into the camera and press the shutter button (Which does have a half-depression for Auto Focus) to start an exposure. The shutter button also has a locking switch that allows for indefinite exposures while the camera is in BULB mode. The device is quite easy to program: 1) Press SET 2) Navigate menus with < and > buttons 3) Change values (Delay Start, Exposure Time, Interval, Number of Shots, and Audio Signals) with up and down buttons 4) Press SET (Optional: Hold Light/Lock button to lock the device as to not change any settings) 5) Press Start to begin the exposure(s) The ONE thing I do not like about this shutter release, is that it does not have a power button. I have read that the power consumption of this device is so eensy weensy, that when idle it would take up to 2 years to drain the two AAA batteries. It is comparable to those LCD bedside clocks. I fixed this "problem" by taking a small plastic tab (saved from the battery compartment of another device) and inserted it between the batteries and the contacts. I do not need to do this but it just makes me feel better about storing this in my camera case for long periods of time. This is definitely worth the money!

No complaints -- does what it's supposed to do for an affordable price. Use it with my Sony a7III.

Great seller and it works very well. You have to watch out when you press the button that you do not slide the side bar up. It is very easy to do.

This is my first electronic shutter release, I did a lot of long exposures but always did them manually with a dummy release and a timer Being able to punch in the exposure time is HUGE I don't know why I went so long without one of these If mine ever fails I'll definitely be picking up another

Good price and works well. I used to have a Nikon MC-36 remote when I shot Nikon, and I picked this up for use with an A9, A7RII, and A6500. The remote works just like the MC-36, so I was used to it, and adds quite a bit of functionality to the camera.

An absolute must for landscape photography. Very affordable and so much more efficient than using a timer to take you shots to eliminate shake. When using ND filters Bulb mode isn't enough often times during sunrise/sets, I can set the timer to 2 minutes and forget it. This makes for a very convenient shoot.

This unit is very intuitive to operate, and it is doing exactly what it is supposed to do. One may find the lack of an on-off switch a drawback, but the batteries are supposed to be taken out when the unit is not in use any way. I've taken great photos with it.

This works great with a tripod for keeping the camera completely still when taking pictures. My particular camera's bracketing features were slightly limited, as the settings that best suited my needs would require me to continually press the shutter. This enabled me to do that without moving the camera at all, and I was able to put together some great HDR images. One last thing, even though this product requires 2 AAA batteries to function, the shutter release button on it WILL still work without batteries.
