Another result of using a wide-angle lens is a greater apparent perspective distortion when the camera is not aligned perpendicularly to the subject: parallel lines converge at the same rate as with a normal lens but converge more due to the wider total field. For example, buildings appear to be falling backward much more severely when the ...
The camera has two VGA 640x480 CMOS sensors, two high-quality wide-angle lens, and a built in USB microphone. [citation needed] According to its website, it is most effective when the user is at a minimum of three feet away. [7] It derives its name from the Japanese term Minoru, which means "reality."

Ultra wide angle lens is a rectilinear which is less than 24 mm of focal length in 35 mm film format, here 14 mm gives 114° and 24 mm gives 84° . Wide-angle lenses (24–35 mm in 35 mm film format) cover between 84° and 64° Normal, or Standard lenses (36–60 mm in 35 mm film format) cover between 62° and 40°
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. [1] [predatory publisher] Some examples of improved optical parameters include the number of pixels, the MTF or the relative illumination.
