Designed for birders and nature enthusiasts, the 10×42 Victory SF Binocular from Zeiss provides an immersive observational experience by combining exceptional optics and a wide field of view in a lightweight and durable housing. Extra-low dispersion fluoride lenses, fully multicoated optics, and phase corrected prisms work together to create images that are clear and bright without distortion across the entire field of view. Colors are accurately represented with high contrast and resolution. The binocular’s 65° wide angle apparent field of view provides expansive views, while the exceptionally short 5′ close focus distance ensures you won’t miss anything.
The optical precision starts with SCHOTT Ultra-FL extra-low dispersion (ED) fluoride (FL) lenses that virtually eliminate distortion and chromatic aberration while increasing contrast and color fidelity. The Schmidt-Pechan roof prisms are coated with Zeiss’ P* phase-correcting coatings to limit light loss and increase color fidelity and contrast. All of the optics are fully multicoated with Zeiss’ anti-reflection T* coatings. These greatly reduce light loss and maximize light transmission to create bright and clear images. A seven-lens eyepiece system uses high-transmission glass and field flatteners to correct for spherical aberrations to allow for pinpoint focusing across the entire field of view.
This SF version of Victory binoculars features the Smart Focus system. Unlike convention focusing wheels that require users to turn the knobs as many as 2.5 times to transition from the minimum to the maximum focus distance, the SF system only requires 1.8 turns. This means faster and easier changes of your subjects without sacrificing focus precision. The binocular is designed with ergonomic balance to reduce the feel of the weight in the hand which reduces user fatigue for comfortable viewing during long observation sessions.
The housing is made from a lightweight, durable, and strong magnesium alloy. A double-hinged open-bridge design provides a larger surface area for gripping while reducing the overall weight even more. The optical tubes are nitrogen-filled and o-ring sealed for water and fogproof performance, giving it a waterproof rating to 400mbar of pressure.
