What to consider when choosing your spotting scope

Objective lens diameter

The objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.

    Ordered this directly from Swarovski. Arrived well packed and protected. Have other Swarovski products and upon examination found this was made to the same exacting standard and quality. In use, just brilliant!!. Makes it so much easier using two eyes instead of one and its magnification is outstanding and even more so with the 1.7x extender. Great kit!

    I’ve ran Vortex and Leopold spotting scopes and hands down Swarovski is the best in glass, smoothness of adjustments, and low light visibility.
