Focusing Distance. You could flick the switch and the lens would not try to focus on the fence allowing you to focus on the players faster. If the closest object in your photo is a patch of grass one meter away from you at the bottom of your composition find something thats about 2 meters away and focus there. Generally a Fieldscope is used to make distant objects appear nearer. Our Canon 50mm f18 lens is a little farther out at 18 inches.
It limits the focus to the farther range 25m so that you dont accidentally focus on something closer. There are few if any long focus lenses produced in modern times but they were once very popular. In the case of DSLR Cameras the distance to the subject is measured from the focal plane mark on the camera body not from the front of the lens. 762017 By focusing on the hyperfocal distance your depth of fieldthe range of your scene that will appear to be in focuswill extend from halfway between your camera and the hyperfocal distance to infinity. If the closest object in your photo is a patch of grass one meter away from you at the bottom of your composition find something thats about 2 meters away and focus there. Infinity is the most extreme distance your lens can focus to.
Our Canon 18-55mm f35-56 zoom lens will focus as close as 11 inches.
And you dont need to use meters or feet or any other standard of measurement. 122019 Hyperfocal distance is the closest focusing distance where elements in your composition at infinity are acceptably sharp. If you focus behind the hyperfocal distance you may end up with a blurry foreground. Some say you cant since the closest focusing distance is over 50 cm. However you can also enjoy magnified images from a short distance such as when observing tree blossoms or butterflies. 5272019 The closest focusing distance of a lens see A below refers to the shortest distance that must be between your subject and the surface of the image sensor the focal plane for the lens to focus.
