Zeiss
The Zeiss SFL 10x50 binoculars bring serious optical performance to hunters, glassers, and long-range spotters who refuse to compromise between clarity and pack weight. Built on Zeiss's reputation for premium glass, these 10-power binoculars deliver the magnification and light-gathering power you need for detailed observation across open country and mid-range hunting scenarios, without the bulk of traditional 50mm models. At just 872 grams (30.8 oz), they're engineered to go where you go—whether you're glassing hillsides, scanning for distant game, or working a spotting situation from a fixed position.
The 10x50 configuration strikes a practical balance: 10x magnification gives you enough zoom to pick out details at distance while maintaining a stable sight picture—crucial when you're handholding binoculars in the field. The 50mm objective lenses gather abundant light, and Zeiss's UHD lens coatings deliver 90% light transmission, so you get a bright, high-contrast image from dawn to dusk. The 5.0mm exit pupil works well in moderate to bright conditions, while the 122-meter field of view at 1000 meters keeps your scanning efficient without tunnel vision.
Built for serious use, the SFL 10x50 is nitrogen-filled and sealed to 400mbar water resistance—meaning they'll handle rain, spray, and rough handling without fogging or leaking. Close focus is a sharp 1.8 meters, so you can observe detail even on near targets. The Schmidt-Pechan prism system is a proven optical formula, and the 18mm eye relief accommodates both bare-eyed and glasses-wearing observers. Zeiss's LotuTec coating sheds water and dust, keeping glass clear in tough conditions.
These are a serious tool for serious glassing, built with Zeiss's uncompromising approach to optical quality and the durability to last decades in the field.
| Magnification | 10x |
| Objective Lens Diameter | 50mm |
| Exit Pupil Diameter | 5.0mm |
| Exit Pupil Distance | 18mm |
| Light Transmission | 90% |
| Field of View (at 1000m) | 122m (366 ft) |
| Subjective Viewing Angle | 66° |
| Close Focus Distance | 1.8m (5.9 ft) |
| Twilight Factor | 22.4 |
| Diopter Adjustment Range | −4.0 to +4.0 dpt |
| Interpupillary Distance Range | 56–74mm |
| Length | 160mm (6.3 in) |
| Width (at 65mm IPD) | 133mm (5.2 in) |
| Weight | 872g (30.8 oz) |
| Water Resistance Rating | 400 mbar |
| Operating Temperature Range | −20°C to +55°C (−4°F to +131°F) |
| Prism System | Schmidt-Pechan |
| Lens Type | UHD |
| Coating | LotuTec |
| Nitrogen-Filled | Yes |
Yes. They're nitrogen-filled and sealed to 400mbar water resistance, which prevents internal fogging and protects against rain, spray, and moisture ingress. The LotuTec coating also sheds water and dust from the external lens surfaces.
The exit pupil is 5.0mm. This works well in moderate to bright conditions typical of daytime hunting and glassing. The 50mm objective and 90% light transmission deliver a bright image, but the 5.0mm exit pupil is more optimized for daylight than deep twilight use.
Yes. The 18mm eye relief is sufficient for eyeglass wearers, allowing you to maintain proper viewing distance while wearing corrective lenses.
The close focus distance is 1.8 meters (5.9 feet), so you can observe detail on nearby subjects as well as distant targets.
