ABSTRACT:
An angle finder housing 8 attachable to the viewfinder eye piece 6 of an SLR camera mounts a bent axis telescopic optical system 8a-8d and a rotatable revolver cylinder 7 offset from but parallel to the optical axis. The cylinder 7 has a through passage 7b, a magnifying lens 7c, and a solid portion 7d spaced from but parallel to each other, whereby the cylinder may be selectively rotated to dispose the passage, the magnifying lens, or the solid portion in the optical axis to implement picture composition, accurate focusing, or reverse incident light blockage, respectively.
