The SVBONY SV535 105mm f/2.8 APO Astro Prime Lens is a fast, full-frame capable triplet apochromatic refractor lens designed specifically for modern astrophotography. Combining a bright f/2.8 aperture, advanced multi-coatings, and a compact, travel-friendly form factor, it delivers wide-field night-sky imaging with excellent colour correction and sharp stellar performance.

Capture the vast cosmos in full glory

With a 105 mm focal length and fast f/2.8 aperture, the SV535 offers a broad and immersive field of view that is ideal for wide-field deep-sky imaging. Large nebulae, Milky Way star clouds, and extended celestial structures can often be captured in a single frame, while the fast optical system reduces exposure times and improves efficiency when imaging faint targets.

APO optical design for cleaner colours

The lens employs a 7-element, 5-group triplet APO optical design engineered to minimise chromatic aberration across the visible spectrum. Compared with simpler achromatic designs, this results in more accurate star colours, reduced colour fringing, and improved edge performance on both full-frame and APS-C sensors.

Fully multi-coated optics

Fully multi-coated (FMC) lens elements enhance contrast, improve colour transmission, and reduce internal reflections. This is especially valuable when imaging bright stars or creating high dynamic range night-sky images with improved background control.

Integrated helical focuser for precise control

A smooth, integrated helical focuser allows fine manual focus adjustments to achieve pinpoint star sharpness. Once set, focus remains stable throughout long imaging sessions, supporting reliable performance without the complexity of motorised focus systems.

Filter and camera compatibility

The rear of the lens features an M42 × 0.75 male thread, making it compatible with a wide range of astrophotography cameras and adapters. The front accepts standard M48 × 0.75 (2-inch) astronomical filters, enabling the use of broadband, narrowband, and light-pollution filters.

Lightweight and travel-ready

Weighing approximately 482 g, the SV535 is well suited to portable imaging rigs, star trackers, and travel setups. Supplied mounting plates support both Vixen-style dovetails and Arca-Swiss systems, providing flexibility for a wide range of mounts and photographic supports.

Designed for reliability and ease of use

Whether you are an experienced astrophotographer or upgrading from conventional photographic lenses, the SV535 provides a purpose-built astro solution with fast optics, APO colour correction, and straightforward manual operation for consistent results under real sky conditions.
