The Swarovski AT Balance 18-45x65 49090 spotting scope have a moving lens that is adjusted by an electric motor (voice coil motor) to offset movements. These motors work particularly quickly, very precisely, and with low friction – the pushing and pulling movements are smooth and continuous. They are also used in applications such as camera autofocus systems.
The integrated gyroscope sensor measures the current movement of the spotting scope. Based on this, a calculation is made to determine which lens movement is necessary to compensate for the motion to result in a stable image. With the stabilization concept of the AT/ST Balance also in movement there is no perceptible “floating” or “after-image”, which is key to the unique natural sense of vision. Automatic locking of the moving lens in the event of a fall or a sudden interruption in the power supply protects the lens while also ensuring the best optical quality by keeping the lens in the central position.

The Swarovski AT Balance 18-45x65 49090 and the ST Balance 14-35x50 49091 are two models with different zoom ranges. The ATB offers higher magnification, while the focus for the ST Balance is on weight (1,470 vs. 1,300 g / 51.9 vs. 45.9 oz). Both are available exclusively in green.
