Enjoy shake-free photography with this Bower RCWUNI wireless remote shutter release that features a range up to 150', so you can control your camera's shutter release from a distance. The shutter lock lets you capture long-exposure photos.
This product is listed as a wireless device, but it reality, it is a wired unit for most of the cameras it works with. I was unhappy with the product not being wireless so I returned it and did not have an opportunity to determine if it was in fact functional.
