Common skin warts (also called cutaneous warts) are raised round or oval growths. A wart may be lighter or darker than the skin around it. Some warts may have tiny black dots in them, often called seeds. The dots are small, clotted blood vessels. Warts may occur alone or in larger groups that merge and form patches.
According to Canon (link):  Canon addressed the âfeedback loopâ in later model IS lenses by introducing an algorithm to the IS detection system to automatically recognise when the lens is mounted to a tripod.
When it comes to travel photography, lighter is preferred, but we couldnât pass up checking out this behemoth of a lens by Canon. Touted at the âlargest and most powerful prime lens ever createdâ for an SLR camera, the Canon 5200mm lens reaches optical zoom ranges of 1000x. The camera is 6 feet long and weighs in at around 220-pounds.
