This Remote Shutter release is made by Viltrox. I have this to do my long exposure photographs when my exposures are 30 seconds or longer. It also works well for doing time lapse photography. It is an automatic time, it can set delay time, exposure time, interval time and the number of shoots for timed interval photography. It will also do single manual release. The timer can be set in 1 second increments going from 1 second to 59 minutes and 59 seconds. It is simple to set up and use (although the instructions are a little difficult to use, once you understand how it works, it is simple to set). The great part is that I used to use the Nikon brand and this one looks just like the Nikon one except that it is a lot less expensive. I have found that they last for a year or two for the last one I had, but that one had the cord permanent mounted to the release, the Viltrox one has a cable that plugs into the unit, this is nice if you have different cameras that you want to use this with or for me, the cable alway wore out where it attached to the unit. This one solves that problem. It works just like the Nikon one, the looks and feel is also the same. So it you are looking to use one for time lapse or just for long exposures this unit works well for the money.
