Follow focus
| Lens Glossary |
A follow focus is a focus-control mechanism used in filmmaking (with film cameras) and in television production (with professional video cameras). there are now follow-focus units that have been designed for use with hdslr cameras that are used to capture video footage.

Focus, английский
- Фокус; фокусировать
- That spot where the wavefront originating at a point on the source is converged to form a point image. fresnel reflection, fresnel lossesthe fraction of the incident radiation specularly reflected by an interface between two media of different refractive indices.
- As a noun, the point where rays of light meet which have been reflected by a mirror or refracted by a lens, giving rise to an image of the source. as a verb, to adjust focal length for the clearest image and smallest spot size.
- Causing light to form a point, or sharp image on the image sensor or film.
- A point through which rays of light converge or from which rays of light appear to diverge when entering or emerging from an optical system.
- 1. the point where light rays converge through a lens 2. the centre of an infection (note: the plural is foci.) verb 1. to adjust a lens until an image is clear and sharp 2. to see clearly he has difficulty in focusing on the object.
- Фокус
- N фокус | a фокусный class
- A point where converging rays or lines meet.
- The search topic selector menu from which you can select an item that an analysis focuses on.
- Position of a viewed object and a lens system relative to one another to offer a distinct image of the object as seen through the lens system. see accommodation and depth of field. focus, principal plane of: single plane actually in focus in a photographic scene.

(2) metaphorical attribute of a borescopic instrument’s depth of field (the range of distance in focus). the depth of field is so great in the case of video borescopes that focusing is unnecessary for most applications. despite the name, no mechanism is actively adjusted. the large depth of field is due both to the small diameter of the lens aperture and to the proximity of the lens to the charge coupled device. focusing, primary: focusing by the lens of the image onto a fiber optic bundle at the tip of a probe. focusing, secondary: focusing at the eyepiece of a borescope or other optical instrument, specifically the manual refocusing needed when the viewing distance changes. footcandle (ftc): disfavored unit of illuminance, where 1 ftc = 1 lm·ft–2 = 10.76 lx. footlambert (ftl): disfavored unit of luminance, where 1 ftl = 3.426 cd·m–2.

Focus lock, английский
- Pre-focusing the camera and then moving it to re-compose the image before capturing it. accomplished by half-pressing the shutter button and keeping it held at that position while moving the camera to another point before pressing it all the way to capture the image.
- In autofocus camera systems, a button, lever, or push-button control that locks focus at a particular distance setting, often used when the main subject is off to the side of the frame or not covered by the autofocus brackets in the viewfinder.
- Focus lock means pre-focussing the subject and re-framing by moving the camera. this is done by half pressing the shutter to focus and fully pressing to expose. done to ensure crisp, sharp eyes for example.
