New Leica Thermals – Calonox 2 View & Sight

A little more than three years ago, Leica Sport Optics introduced their first thermals. It’s now time for an upgraded version called the Leica Calonox available in four different versions: Leica Calonox 2 View and Leica Calonox 2 Sight, both with Laser Range Finding versions.

Leica Sport Optics @ TFB:

In terms of technology, the Calonox 2s come with a Lynred thermal sensor with 640×480 pixels (12 μm) and a NETD of

According to Leica, this is the first thermal imaging clip-on camera with integrated rangefinding up to 1200 meters.

Thermals have quickly but steadily become a must for many hunters. Have you tried them yet?

Below you can find Leica Sport Optics’ product announcement:

For ethical hunting and precise identification of wildlife
New Leica thermal cameras combine high performance, optimum ergonomics, and rangefinding

With the Leica Calonox 2, Leica Sport Optics presents a new generation of thermal
imaging technology and, with the Calonox 2 Sight LRF, the first thermal imaging clip-on
camera with a built-in laser rangefinder. The renowned German optics company thus
sets a further milestone in optoelectronic devices used for hunting and nature
observation. The Leica Calonox 2 series comprises four new thermal imaging models:
two clip-on cameras (Calonox 2 Sight) and two observation cameras (Calonox 2 View) –
each available with or without a rangefinder.

Triple excellence – performance, design, and rangefinding

The new Leica thermal cameras are designed and made in Germany. Leica uses only
European components for the essential parts such as special lenses and sensors.
Together, highest-quality components and highest-precision manufacturing achieve the
legendary perfection valued by Leica customers.

Wetzlar, Germany. September 11, 2023. Thermal cameras require no light and can be used in complete darkness. Sophisticated sensors react to thermal radiation from the targeted object and visualize it on a microdisplay. Thermal cameras can also be used during the day.
The scene then appears different than in natural sunlight, but offers advantages such as quickly detecting animals that are naturally camouflaged. Electronic color filters and individually adjustable image modes support and optimize the user’s experience.

Thermal cameras are suitable for a wide range of applications – finding and counting wildlife, for example. On legal night hunts, the thermal imaging clip-on camera turns a normal riflescope into a night targeting device. Since estimating distance through a thermal camera is very difficult, the Leica Calonox 2 Sight has an additional rangefinder (LRF stands for “laser rangefinder”). This ensures knowledge of the exact range and eliminates the risk of a bad shot due to misjudged distance. In the only thermal imaging clip-on camera with an integrated rangefinder, all the advantages are combined in one device.

01. Ideal sensor for a natural, sharp, high-contrast image Featuring a high-quality sensor from LYNRED, the Leica Calonox 2 is state-of-the-art for hunters and nature observers alike. The sensor has a size of 640×480 pixels and has a pixel size of 12
μm. This guarantees a sharp, high-contrast image. An object with the standard size of 1.8 meters can be clearly detected at up to 2210 meters. Recognition is possible at 770 meters and reliable identification at 390 meters.

The LIOTM (Leica Image Optimization) software, further refined by Leica, ensures optimum images. With a sampling frequency of 60 hertz, panning the device also results in a smooth image. Likewise, video recordings of moving objects are possible without disturbing interruptions. The NETD (Noise Equivalent Temperature Difference) of the Calonox 2 sensor is

The recommended retail prices (RRP) for the Leica Calonox 2 models are:
Leica Calonox 2 View / 4700 euros
Leica Calonox 2 View LRF / 5700 euros
Leica Calonox 2 Sight / 4700 euros
Leica Calonox 2 Sight LRF / 5700 euros

Delivery start for the Calonox 2 models:
Leica Calonox 2 Sight and Calonox 2 Sight LRF End of January 2024
Leica Calonox 2 View and Calonox 2 View LRF End of February 2024

Here’s a video about the Calonox, which I think is a good representation of how many traditional hunters think:

    3-5k USD for thermals with similar performance to an ATN ThOR at 900-1500 USD. Somebody needs to sit down the clip on fanatics and tell them about picatinny and repeatable zero.

      @DanMcKraken Can't use stand-alone thermals in certain jurisdictions.

    Won't be long before cheapo Chinese Android phones have 640x480 thermal sensors. Honestly probably 10-15 years.
