SVBONY SV135

One Eyepiece – Many Views

The SVBONY SV135 offers a seamless zoom from 7 mm to 21 mm, eliminating the need to swap eyepieces. Its smooth and precise zoom control makes it easy to adjust magnification without disturbing your target or losing focus.

Premium Optical Design

Featuring a 6-element, 4-group optical layout with fully multi-coated glass, the SV135 delivers sharp, high-contrast images with excellent light transmission.

Wide Yet Practical Field of View

The apparent field of view ranges from approximately 57° at low magnification down to 40° at high magnification, allowing you to frame your target cleanly while increasing detail at higher powers.

Comfortable Viewing

Eye relief ranges from 18 mm at low power to 16.3 mm at high power, making the eyepiece comfortable to use even with glasses. A rubber eye guard helps block stray light for improved contrast.
