The object distance is infinite and the full field-of-view angle is 4° × 4°. The focal length is 450 mm. The entrance pupil diameter is 50 mm. The F-number is 9. The primary system wavelength is 587.6 nm. After 35.3 h of computation without human interaction, a...
Below, I share a few of the most common focal lengths you’ll encounter in photography. I’ve made sure to note the pros and cons of each, and I’ve also noted when each focal length is generally used. Of course, photography is a creative activity, so don’t feel hemmed in by any...
HiLens Kit cameras have a fixed focal length of 2.8 mm, a wide angle of 120 degrees, and a surveillance distance of 0 to 4 meters. Its focal length cannot be adjusted.
The optical zoom of a camera system is the ratio between the smallest and largest focal length. A camera system with 12 to 120 millimeters, therefore, has a 10x zoom. In the case of smartphones, however, the manufacturers usually calculate from the main camera—from 24 to 120 millimeters ...
