Many photographers and cinematographers still use UV filters to protect their lenses' glass and coating. However, UV filters, as with any optical filter, may introduce lens flare and harm contrast and sharpness. Hoods can counteract this, as they offer some protection against impact and shade optical elements, thus preventing lens flare.
The lenses of these cameras are removed and then these are attached to telescopes to record images, videos, or both. In newer techniques, videos of very faint objects are taken and the sharpest frames of the video are 'stacked' together to obtain a still image of respectable contrast.
In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at its minimum desired value, then, when shutter speed reaches the user-defined limit, the ISO is increased, up to the maximum value. [5] All of the above functions are independent of lens focus and stabilizing methods.

Lens caps or covers are often lost, they are not a high value item among photographers, especially professionals, photographers at large events or in large crowds may drop their lens caps and fail to retrieve them, leading to a litter of lens caps. [citation needed] A lens cap may be tethered to the camera via a string to avoid losing it. Aside ...
Arguments for the use of protection filters include: If the lens is dropped, the filter may well suffer scratches or breakage instead of the front lens element. The filter can be cleaned frequently without damage to the lens surface or coatings; a filter scratched by cleaning is much less expensive to replace than a lens.
Uncoated glasses lens (top) versus lens with anti-reflective coating. The reflection from the coated lens is tinted because the coating works better at some wavelengths than others. An antireflective , antiglare or anti-reflection ( AR ) coating is a type of optical coating applied to the surface of lenses , other optical elements, and ...
Whole sky camera also popularly known as an all-sky camera in the astronomical field is used for meteor, fireball, and spacecraft reentry recording and identification. While mostly identical to the meteorological application, the system for astronomical use tends to have a more sensitive night camera and much longer exposure due to the night ...
