For instance, a 200mm lens requires a shutter speed of 250th of a second. A 300mm lens demands 500th of a second. And so on. This is a situation where fast film is a must for traditional still photography. It's another instance why digital cameras can be far superior. A telephoto lens can also be made "longer" by adding either a 2x or a 1.5x extender. A 2x extender, for instance, doubles the focal length of the lens, so a 300mm lens immediately becomes a 600mm but at greatly reduced cost.
On many autofocus cameras, extenders work best for scenics and closeups, since the extender must be manually focused. An extender also takes away one or two F-stops depending on its power. A tripod is often needed when adding an extender. Shooting in Low Light Situations Or, why we love digital cameras so much! Approaching Animals The
