Kilfitt was the first company to make a really fast and easy-focusing long telephoto lens for action work, used mostly by nature and sports/action shooters, but on a pretty limited basis. Shooting sports with manual focusing cameras and lenses was done as early as the 1880's, as far as I know, with very big Graflex plate box reflex type cameras, mostly for Major League Baseball games. These cameras were BIG!
In 1976, Nikon premiered the world's fastest 400mm telephoto, the 400mm f/3.5 ED~IF, an internal focusing lens, which had an adjustable focus tensioning system, allowing the user to make the focusing feather-touch, to quite heavy, and the lens also had a focusing pre-set "stop" which could be set by focusing on the desired distance, then turning the set-screw; the focusing ring would literally stop when it was cranked to that spot, but with more effort, the focusing ring could easily be moved past the pre-set distance, in either close or far directions.
The 400/3.5 is actually fairly easy to use for action sports. I've shot football, baseball, and track and field with mine, which is the 1981 Ai-S model. It had a "little brother", the 300mm f/4.5 ED~IF, which lacked the pre-set distance stop.
The 300mm f/4.5 on the right, when it is in proper order, has an exceptionally light, feather-touch focusing action; in both of these lens designs, only some very small and lightweight Internal Focusing elements move during the focusing process. The bigger, heavier front elements do not move at all, and focus ring movement is silky-smooth and very precise and well-damped.
