The Impact DVS-TP20-37 2.0x High-grade Telephoto Converter Lens converts the focal distance of the body lens by a factor of approximately 2.0 when attached. With the use of multi coated and low-dispersion glass, this converter provides superior image quality and minimizes image distortion. It eliminates flare, ghosting, reflection and refraction - all before it hits the camera's original lens. This results in your camera capturing a much cleaner image.
The DVS-TP20-37 screws right onto your camera's existing lens system, and will attach directly to lenses with 37mm filter threads. In addition, a 34-37mm step-up ring is also included to make it compatible with 34mm threaded lenses.
