Expanded Zeiss SFL 10x40 Binoculars Key Features:

Impressive Optics

Featuring extra-low dispersion fluoride lenses, these binos offer a wide field of view to showcase everything with sharp details and high clarity, so that you won’t miss anything. In addition, the Zeiss SFL binoculars offer 10x magnification to focus on distant subjects while the 40 mm lenses ensure high definition rendering. Colours are accurately represented with optimum contrast, thanks to the multiple coatings the lenses have.

The SCHOTT ultra-low dispersion fluoride lenses promise to minimise issues, such as chromatic aberrations and distortions across the entire field of view, rewarding you with crisp and clean images in daylight as well as during low-light conditions.

Lightweight Craft

Designed specifically to meet the demands of birders and hunters, these binoculars feature a compact and lightweight design that makes them easy to carry anywhere. By reducing the distance between lens elements in the optical design, the SFL series binos offer optimal compactness while retaining the high optical performance they are characterised by. The overall lightweight construction comes in handy when you are looking forward to fatigue-free and prolonged observation sessions.


A versatile combination of optimised coating promotes a truly natural and transparent viewing experience. Relying on phase-correction coatings, SFL provides exceptional colour fidelity, high image resolution, and exceptional detail recognition of every subject and surroundings. Plus, there’s a proprietary anti-reflection coating on the lens that ensures maximum light transmission to offer true-to-detail brightness and contrast, allowing you to identify subjects without fault even in low-light conditions.

Additionally, there’s a seven-lens eyepiece system combined with high-transmission elements and field flatteners that can be relied on under all circumstances to provide sharp edge-to-edge focusing.

Smart Focus System

Zeiss SFL binoculars are equipped with a Smart Focus system that ensures magnification from minimum to maximum in just 1.4 turns of the wheel. With this fast and precise focusing technology, these binos facilitate rapid change in magnification to bring the subjects in clear focus, especially fast-moving ones. Moreover, the focusing wheel is placed efficiently to minimise hand and finger fatigue, providing longer observation sessions.

If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.

Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
