  • APO Spotting Scope SA401 25-75x100 Double ED

    The SVBONY APO Spotting Scope SA401 25-75x100 pairs a 100mm double ED apochromatic objective with a 25-75x zoom eyepiece on a 556.2mm focal length. The detachable 1.25" eyepiece can be combined with the SVBONY SC001 WiFi camera (sold separately) to share live views on your phone. Rubber armor, nitrogen filling and IPX5 waterproofing make it ready for birding and long-distance observation in the field.

    SA401 APO Optics: High-Contrast, Chromatic-Free Views

    The core of the SA401 is its 100mm apochromatic objective lens, which utilizes double Extra-low Dispersion (ED) glass elements. This design corrects for chromatic aberration, eliminating the distracting color fringing seen on high-contrast subjects in standard scopes. Views are rendered with sharp, true-to-color detail from edge to edge.

    Fully multi-coated (FMC) optics maximize light transmission, ensuring bright, clear images even during twilight hours. Whether you are identifying distant birds or resolving details on the lunar surface, the optical system is engineered for maximum contrast and clarity across the entire 25-75x magnification range.

    25-75x Zoom Eyepiece with Twist-up Eyecup

    The zoom eyepiece uses 8 elements in 5 groups and a twist-up eyecup, with 20.0mm to 18.0mm of eye relief for comfortable viewing with or without glasses. The exit pupil runs from 4mm at 25x to 1.3mm at 75x, and the field of view from 31m to 16m at 1000m (93ft to 48ft at 1000 yards).

    The eyepiece is a 1.25-inch universal plug-in design, so it can be swapped for other 1.25" eyepieces or for the SVBONY SC001 WiFi camera (sold separately) to download and share photos in real time.

    Standard Tripod Thread and 360° Rotation

    A standard 1/4"-20 tapped hole lets you mount the SA401 on tripods of different sizes. The scope rotates through 360 degrees: loosen the screw counterclockwise, turn the scope to the angle you want, then tighten the screw clockwise.

    A built-in sunshade protects the objective from raindrops and snow, and the 10m near focus distance lets you observe close subjects as well as distant ones.

    Field-Ready Build with Rapid Hand-Wheel Focus

    The SA401 is built to withstand the elements, featuring a durable rubber armor that provides a secure grip and protection from bumps and scrapes. The chassis is sealed to be IPX5 waterproof and is nitrogen-purged to prevent internal fogging in changing temperatures, ensuring reliable operation in any weather.

    A large, oversized hand wheel provides fast and precise focusing. This rapid focus mechanism allows you to quickly acquire and track moving subjects, like birds in flight, without losing critical detail.

  • What is the benefit of the SA401's APO objective for observation?

    An Apochromatic (APO) objective uses special glass elements, in this case Double ED glass, to bring all colors of light to the same focal point. This eliminates chromatic aberration, or false color fringing, which is especially noticeable on high-contrast targets like a bird against a bright sky or the limb of the Moon. The result is a sharper, higher-contrast, and more color-accurate image.

    Can I use a camera with the SA401 spotting scope?

    Yes. The SA401 has a detachable 1.25" eyepiece, so the SVBONY SC001 WiFi camera (sold separately) can be fitted to watch the view on your phone and share photos in real time. No camera is included with the scope.

    What are the SA401's eye relief, exit pupil and field of view?

    Eye relief is 20.0mm to 18.0mm, the exit pupil runs from 4mm at 25x to 1.3mm at 75x, and the field of view is 31m to 16m at 1000m (93ft to 48ft at 1000 yards). Near focus distance is 10m.

    Can I use the SA401 scope for birdwatching in rainy conditions?

    Yes. The SA401 spotting scope is IPX5 waterproof, meaning it is protected against low-pressure water jets from any direction. It is also nitrogen-purged to be fog-proof. This makes it a reliable tool for use in damp or rainy weather without risking damage to the internal optics.

    How heavy is the SA401 and how do I mount it?

    The SA401 weighs 2900g and is 458mm long. It mounts on a tripod through a standard 1/4"-20 tapped hole, and the scope rotates 360 degrees so you can set a comfortable viewing angle.

    Does the SA401 need batteries or power?

    No. The SA401 is an optical spotting scope with a manual focus wheel and needs no batteries or power source.
