This SEALUX development offers the photographer a brillant picture like with the sport viewfinder. The high-quality optical system, multicoated, enlarges the monitoring picture to a fantastic scale of reproduction. For this the eyepiece of the viewfinder is moved upwards, parallel to the lens. This enables the photographer the complete look on the picture, the adjusted data while watching the surrounding at the same time. A real action viewfinder! The viewfinder is most suitable for quick changing from upright to broadside format as well as for half-half photographs. Persons who wear glasses can still effect the diopter setting on the camera ocular.
