This VL152 Bower 52mm Right Angle Mirror Lens Attachment is a classic "deceptive angle" photographic device. It allows photographs to be taken at 90° right angles of the camera. This means you can keep the camera pointed straight ahead, while actually photographing subjects to your right or to your left. The attachment rotates 360°. Designed to be used on lenses with 52mm filter threads, or with bigger sizes with the use of step-up rings.
