Great quality and Great alternative compared to Sony RM-S1AM and the Minolta RC-1000. It is handy for reducing camera shake on super telephoto shots, macro-photography, and bulb exposures. Pressing the shutter button halfway enables auto-focusing; pressing the shutter button all the way down releases the shutter. Lock the button for long exposures or continuous shooting.
