Kenko SG-Z 20-100x30N Zoom Binoculars 20×–100×

Kenko SG-Z 20-100X30N FMC is an ultra-high magnification zoom binocular that covers 20× to 100× for distant viewing with an included tripod phone holder and twin loupe.

These compact zoom binoculars let you shift from wide 20× views to extreme 100× close-ups in a single device. With a 30mm objective, full multi-coating (FMC) optics and a tripod adapter included, the SG-Z balances reach and portability for outdoor observation, events, and moonwatching. The set also includes a 50mm twin loupe and a tripod-mount holder for stabilized, hands-free viewing and smartphone attachment.

How clear are images at different magnifications?

The SG-Z uses full-multi-coated lenses to maintain contrast across the 20×–100× range, but image steadiness and brightness change with magnification. Lower magnification gives a wider, brighter field; higher magnification narrows the field and reduces apparent brightness, so a tripod is recommended for sharp views at upper settings.

• Magnification range: 20× to 100× for flexible framing.
• Objective diameter: 30mm balances light gathering and size.
• Brightness drops from 2.25 to 0.09 as magnification increases.
• Angular field: 1.3°–0.5° (field at 1000 m: 22.7–8.9 m).

Can I use this for moon, concerts, and wildlife?

Yes — the SG-Z is built for varied outdoor use. At lower zooms it’s suitable for concerts and nearby wildlife, while the high end approaches lunar detail; however, atmospheric conditions and stability affect detail level, so always start low and zoom in gradually.

• Moon: high magnification helps reveal larger surface features.
• Concerts/sports: 20× gives useful framing for distant stages.
• Wildlife: closer subjects work best at mid-range zooms.
• Tip: begin at 20× then increase to locate and refine the subject.

How do I keep views steady at 100×?

Stability is essential at extreme zoom. The SG-Z ships with a tripod holder designed to attach to any standard camera tripod for firm mounting; for smartphone photos, use the holder to reduce shake and align the camera with the eyepiece.

• Included tripod holder mounts to standard camera tripods for stability.
• Use the supplied twin loupe and phone adapter for aligned imaging.
• Start with low magnification to locate targets, then increase.
• Eye relief ranges 19.9–9.5 mm for comfortable viewing with/without glasses.

What are the physical and optical specifications?

The SG-Z is compact and reasonably lightweight for a high-zoom unit, making it easy to carry for field trips and events. Key specs are listed so you can match the binocular to your needs for travel, tripod use, and handheld spotting.

• Size: 159 × 58 × 162 mm; Weight: 600 g — easy to pack.
• Eye width adjustable: 58–74 mm to fit different users.
• Close focus: 10 m — not for very close macro viewing.
• Country of origin: Philippines; package weight about 1.14 kg.
