The optics in the LENS2SCOPE magnify the image by a factor of 10x so that a 100mm lens would have the same magnification as a 1,000mm lens when viewing. Focus is easily achieved by using the lens' manual focus ring.
The LENS2SCOPE has a removable tripod adapter for mounting onto a tripod for more comfortable viewing for extended periods of time.
This small accessory comes with its own carrying case and takes up about as much room in a camera bag as a normal lens.
