⚡ At a Glance
- • Image Quality: Bright, clear field of vision thanks to large-aperture optics
- • Best for: Wildlife observers and birdwatchers needing low-light performance
- • Not ideal for: Users who require ultra-compact, pocket-sized optics
Porro prism construction pairs with more-than-40mm objective lenses and 8x magnification. Multi-coating reduces unwanted reflections while an ergonomic exterior aids handling.
Brighter views in low light, with large-aperture objective lenses
Objective lenses exceed 40 millimetres in aperture, increasing light-gathering power and improving image brightness. The 8x magnification keeps scenes steady while using the larger lenses.
Brighter images at dawn and dusk make identifying birds and distant subjects easier. Less eye strain results from stronger light transmission.
Improved contrast and reduced glare, with multi-coating and Porro prisms
Multi-coating on optical surfaces minimises internal reflections and preserves contrast, while Porro prism geometry enhances depth perception. Coatings work across lens surfaces to maintain colour fidelity.
Cleaner, higher-contrast views help distinguish plumage and fine details in varied light. Colours remain truer, aiding accurate observation.
Stable handling and longer sessions, with ergonomic focus ring and tripod option
A conveniently placed focus ring allows quick manual adjustments, while the optional TP-3 tripod adapter enables secure mounting for hands-free use. A rubber exterior improves grip and protects the body.
Fast focusing helps lock onto moving subjects without fumbling. Tripod compatibility reduces fatigue during prolonged observation or when using higher magnification for steady views.
