Zeiss SFL 8x50

The new SFL 8x50 binoculars from Zeiss have a large field of view, a short close focus limit, and a high transmission value.SFL stands for "SmartFocus & Lightweight". Zeiss has established the SFL series on the market to meet the desire of hunters for lightweight and compact binoculars. The previous x30 and x40 models have since enjoyed great popularity. Now, Zeiss presents 3 versions with a 50 mm objective lens, which maintain the compact design of 42 mm instruments. The SFL 8x50 is the binocular with the largest field of view in the 50 series, making it ideal for tracking fast game, hunting in expansive landscapes, and use in the forest.The optical systemThe very good optical performance of the SFL 8x50 is due to Zeiss's UHD concept. "Ultra High Definition" guarantees a true-to-nature reproduction of colors through optimal tuning of the optical design and lens coatings. A transmission value of 90% allows for observation until late twilight. The large exit pupil ensures comfortable viewing behavior. The close focus limit is only 1.8 m. The lenses naturally feature T* coating and LotuTec technology. The Schmidt-Pechan roof prisms and ED glasses (Extra Low-Dispersion) minimize chromatic aberration, and the SFL 8x50 exhibits almost no imaging errors. The field of view is an impressive 131 m at 1,000 m.The ergonomicsThe "SmartFocus" concept stands for the ergonomically perfect position of the large focusing wheel. This prevents overstretching of the finger when adjusting. With only 1.4 turns, one can switch from close focus to infinity. Quick and precise focusing is still possible even when the cold season necessitates wearing gloves during hunting. The center of gravity of the SFL 8x50 is shifted towards the eyepiece, which balances the weight in the hand and allows for longer observation without fatigue. The completely removable eyecups are made of soft rubber and are adjustable in 5 positions.The housingThe low weight of 855 g for a 50 mm binocular and the compact size with a length of only 160 mm, which is usually only found in 42 mm models, have been made possible by a lightweight yet durable magnesium housing and by thinner lens elements placed at a smaller distance. These construction principles do not affect the performance of the instrument. In addition to the robust housing, the armor made of natural rubber, a latex-free NBR mixture, provides additional protection. The housing is filled with nitrogen to prevent internal fogging and is waterproof up to 400 mbar. The SFL 8x50 can be used in a temperature range of -20 °C to 55 °C. It has an interface for the optional attachment of a tripod adapter.Scope of deliverySFL binocularsCarrying case including strapEyepiece protection capsObjective protection capsStandard carrying strapOptics cleaning clothQuick guideSafety instructionsTechnical dataType: Full-size binocularTransmission: 90%Magnification: 8xObjective diameter: 50 mmExit pupil diameter: 6.25 mmDawn number: 20Field of view: 131 m at 1,000 mSubjective field of view: 58°Close focus limit: 1.8 mDiopter adjustment: ±4 dptExit pupil distance: 20 mmPupil distance: 56-74 mmPrism system: Schmidt-PechanCoating: LotuTec® / T*Housing: MagnesiumArmor: Natural rubberNitrogen fillingWaterproof up to 400 mbarOperating temperature -20 °C to 55 °CInterface for tripod adapterLength: 160 mmWidth at an eye distance of 65 mm: 133 mmWeight: 855 g
