The SVBONY SV555 is a small Petzval APO triplet refractor built for deep-sky astrophotography. Its four-element design gives a flat field across a 44mm full-frame sensor, so stars stay round to the corners without a separate flattener. The variable aperture runs from F4.5 to F22 and the tube rotates 360 degrees, with an M72 front thread and a 2-inch filter holder in the mount kit. It suits wide-field imagers who want a light, travel-friendly rig, and it is EAF-ready for ZWO EAF Gen1 autofocus.

The SVBONY SV555 is an APO astrophotography lens built around a Petzval triplet structure. The design is meant to deliver a flat field and to eliminate coma and chromatic aberration for deep-sky imaging.
It is designed for 44mm full-frame sensors and covers them without vignetting. It works with DSLR, mirrorless, and astronomy cameras. The aperture is adjustable from F4.5 to F22. The upgraded focus system offers focus travel between 2.67mm and 3.22mm for fine adjustment. The lens weighs 90g less than previous models.
The lens is EAF ready, with an EAF adapter pre-installed and compatibility with the ZWO EAF Gen1. A mount kit is included with a 2-inch filter holder and an M72 front thread. The tube rotates 360 degrees to change the shooting angle.
