Essential accessory for shooting up especially at telephoto, and even with standard lens, no risk of blur, and allows very long exposure time, also ideal for macro and bulb in a first pressure opens the shutter, the second closes the. I use a Nikon F65 and a silver Nikon D60, excellent product for a more than fair price. Also the lifetime of the lithium battery is 5 years and its weight is negligible (10g). possibility to fix the holster on the belt of the machine, really useful!
