We are using low dispersion aspheric lens architectures (110° and 26° diagonal fields of view, respectively for the wide and tele lenses). The optical units are composed of six lenses optimized to minimize the level of parasitic light while providing a high-resolution image across a vast temperature range (-43 °C to 45 °C).
Diagonal (DFOV) and Horizontal (HFOV) fields of view
The lens of the wide camera covers the full diagonal of the sensor with a 110° DFOV. It brings a 69° HFOV for the standard video mode, and a 75° HFOV for the standard photo mode.
The lens of the tele camera covers the full diagonal of the sensor with a 26° DFOV. It brings a 16° HFOV for the standard video mode, and a 16° HFOV for the standard photo mode.
Lossless zoom capabilities
The conception of ANAFI USA’s optical unit enables the drone to achieve 5x lossless zoom in 4K-UHD (3840x2160 px), 10x lossless zoom in Full HD (1920x1080 px) and 15x lossless zoom in HD (1280x720 px). Finally, at 27x zoom, ANAFI USA images still reach DVD quality (720x480 px).
Angular resolution and discernable details
The angular resolution of a lens expresses the angular separation between two pixels of the associated sensor. With the angular resolution of 0.004° on its telephoto lens, ANAFI USA enables its users to discern 10 cm (about 4’’) details at a distance of 1,500 m (about 0.93 miles), or 1 cm (about 0.4’’) details at 150 m (about 164 yards).
