Lens Autofocus Distance at Henry Horning blog

Lens Autofocus Distance. The hyperfocal distance of a lens is the distance from the camera lens to an optimal point of focus that maximizes the depth of field in the image. Most modern cameras come with an autofocus (af) lens, so whether you are using a dslr or your smartphone, you’ve probably used autofocus many times. Also, the filter thread at the front of the lens does not rotate, which is convenient if you’re using a polarizing filter. When you focus by turning the focus ring on the lens barrel, you are adjusting the distance lens to image sensor / film in an attempt to kiss. Smaller maximum apertures like f/5.6 mean less light passing through the lens, making autofocus operation more difficult. Benefits include fast autofocusing and a short minimum focusing distance. For example, if you’re checking a 35mm lens, you’d calculate this distance 35mmx50=1750mm. 1750mm = 1.75 meters or. Ideally, the lens aperture should be between f/2.0 and f/2.8 for the best autofocus performance. By focusing on this optimal point—the hyperfocal point—as much of the scene as is possible for that lens and aperture setting will be in acceptable focus from near to far. If you’ve been curious about what autofocus lenses are and how they work, you’ll find much to learn, including the many differences between af lenses and manual ones.
