Swarovski ATX/STX/BTX 65mm Modular Objective

The Swarovski Optik ATX/STX/BTX 65mm Objective Lens Module has an updated tripod shoe that fits Arca-Swiss quick release tripod adapters, and will accept any of the three available eyepiece modules: straight (STX) or angled-viewing (ATX), or the binocular viewer (BTX). The bayonet mount for the eyepiece makes it quick and easy for users to swap out objectives and eyepieces to adapt to any hunt.

Swarovski combines the legendary image quality and world-class workmanship that hunters, nature enthusiasts, tactical professionals, and researchers have come to expect from the brand. The 65mm objective strikes a nice balance between light-gathering capability and portability, making it well suited for the backpack hunter.  Extra-low dispersion fluoride glass elements efficiently transmit all wavelengths of visible light, resulting in bright images that are color faithful, crisp, and rich with detail. An integrated field-flattener lens system corrects spherical aberrations to reveal crisp details at the edges of the view without distortion. SWARODUR and SWAROTOP coatings on all lenses and prisms minimize glare while maximizing contrast.

Complementing the optical performance and technologies is a lightweight and durable magnesium-alloy chassis that is wrapped in a protective rubber armor. Its optical tubes are nitrogen filled and O-ring sealed to be dustproof, waterproof and submersible, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. The tripod collar has a 1/4″-20 socket on the bottom of the Arca-Swiss-compatible shoe and a rotating collar to allow for precise eyepiece placement relative to the mounting system.

This is a nice little objective and if you already have an ATX or BTX with a larger objective, this is a no-brainer to add to your kit.  It’s far more compact and lighter for those trips when you’ve got to find a way to cut some weight from your pack.  It’s a big step forward in quality over prior 65mm offerings.
