The Svbony SV555 APO 54 mm f/4.5 is a professional prime lens designed for astrophotography with cameras and camcorders equipped with a full-frame sensor.

The optical system of this lens consists of five elements arranged in three groups. To ensure the highest image detail and appropriate contrast, the lenses are covered with full multi-layer coating (FMC). The optics of this lens have been designed in such a way that it is possible to obtain a large diameter of the circle of full illumination, necessary to eliminate vignetting at the edge of full-frame matrices. The lens also has an adjustable diaphragm, the number of which can be adjusted in the range from f/4.5 to f/22.

The Svbony SV555 APO 54mm f/4.5 is mounted in a solid mounting clamp equipped with a Vixen socket for placing a guide scope, astrophotography computer or electronic focuser type EAF. The whole can be mounted on the mount via a Dovetail foot.
