Sorted by: 9. Binocular zoom and lens focal length just aren't equivalent and can't be converted in any meaningful way. A camera lens is an image-forming system. It has a focal length. Binoculars and telescopes (with eyepiece in place) are "afocal" systems — there's no focal plane onto which the image converges.
Cons: Optical zoom security cameras are almost preferred in every way except for the below 2 reasons: Optical zoom will lessen the viewing angle when you zoom in to get image details. Optical zoom can’t be added after video is recorded. 2. Advantages and Disadvantages of IP Surveillance Cameras with Digital Zoom.The E1 Zoom has pan-and-tilt capability with a 3x optical zoom. The E1 Zoom’s basic security features are identical to the E1 Pro: real-time alerts, two-way talk, a siren that can be triggered
Single SIM (Nano-SIM and/or eSIM) or Hybrid Dual SIM (Nano-SIM, dual stand-by) telephoto), 1/1.72", 0.8µm, PDAF, OIS, 1.1x optical zoom, 3x hybrid zoom 12 MP, fMany cameras have a 10X optical zoom. This often translates to covering a 35mm FF equivalent of approximately 30mm to 300mm. Digital zoom. Beware of zoom ranges that include digital zoom. When an optical zoom is used to push from a wide to a telephoto shot, the camera still captures the full active area of the image sensor. Wka7286.
