Description Technical Info Reviews

The Sirius series includes pro-grade thermal sensors, state-of-the-art objective glass and AI-powered image calibration. The bright 0.49' 1920×1080 OLED screen offers a clear view that minimises eye fatigue during extended observations.

The models are characterised by an embossed 'X' symbol on the focus wheel, carbon fibre accents and a power button integrated into the Pixfra logo. The power states are indicated when the button glows in one of the five brightness settings. This button can be turned off for total darkness.

They have three buttons for an easy one-handed operation. Their metal lens caps are resistant to dust, scratches, and impact, preserving the clarity of the lens.

The Sirius S435, S635, S650, and S650D offer varying features, from the S435's 2.41x magnification and 1800m detection range to the S650's powerful 50mm f0.9 objective lens and extended 2600m detection range. The S650D stands out with its dual objective lenses, and the user can switch between a 25mm f0.88 wide-field lens and a 50mm f1.1.
