Field of View: The field of view of a lens (sometimes called the angle of coverage or angle of view) is defined as the angle (in object space) over which objects are recorded on the film or sensor in a camera.
Field of view at 1000m
A distance, or angle, measure given by binocular manufacturers that's similar to angle of view on a lens. It's usually indicated in degrees or as a width in meters at 1000m.

Field Of View crop
One thing it is important to understand is Field of View crop.
field of view
volume in space defined by a cone extending out from the focal plane of a camera.
FIFO
acroynm for first in, first out.
Field of View - please see FOV below.
File - A collection of information, such as text, data, or images saved on a disk or hard drive.
Field of View: When a photographer views a scene, the photographer has a very wide field of view.
The field of view in a DSLR camera with a 1.6X multiplier is equivalent to what you would see with a 35mm SLR and lens with a focal length 1.6 times longer. Using the image example above you can see that a DSLR with a 1.

To get the same field of view of a 55mm lens as used on a FF DSLR, you will need to use a (55 / FLM) = 34mm lens on a APS DSLR.
FOV - Field of View The size of an imaged or visual scene in terms of sky dimensions, usually stated in degrees, arcminutes, or arcseconds.
In each case the field of view provided by the lens isn't appropriate for your subject matter. In the first instance your lens is not "wide" enough to take in the whole scene, and in the second your lens isn't "long" enough.
Common values for field of view crop in DSLRs include 1.3x for some Canon sensors, 1.5x for Sony APS-C sensors used by Nikon, Pentax and Konica Minolta and for Fujifilm sensors, 1.6 (APS-C) for most Canon sensors, ~1.
moving straight towards or straight away from the camera, it may appear as though it is hardly moving and a fast shutter speed is not required to produce a sharp image; however, when that same subject moves at the same speed across the field of view ...
Because the correlation between the focal length and the field of view was standardized when film cameras were the norm.
The lens also determines the field of view and influences the depth of field of the scene.
An adjustable diaphragm, usually an overlapping circle of metal leaves, that creates an adjustable hole called an aperture.
As focal length increases, the field of view narrows and you can isolate smaller portions of the setup without moving closer.
Magnification is related to the lens' angle of view.
A telephoto lens has a longer focal length and narrower field of view than a normal lens and have a shallower depth of field than wide angle lenses.
In fact, since we would end up with the same field of view, any camera movement would affect the resulting image by the same amount.
What I mean by this is if you have a very long lens, the viewing angle for the photograph will be much narrower because light from the far left field of view and far right field of view can't make it to the sensor.
A normal lens has a shorter focal length and a wider field of view than a telephoto lens, and a longer focal length and narrower field of view than a wide-angle lens.

The choice of a lens is determined by the desired field of view, the available studio space, and the nature of your project.
The full moon occupies about 1/2 of 1 degree of our field of view as you look up into the heavens. A rough guide is that if you divide the length of your lens by 100, you'll get an approximate idea of how big the image of the moon you record.
Focal Length determines the field of view of our camera. The human eye has a field of view that is comparable to that of a 50mm lens on a 35mm film camera. We therefore consider 50mm the standard focal length.
Focal length determines field of view, which varies from lens to lens. A wide angle lens -- for instance, a 24mm lens -- has a very broad field of view and is often used for landscape photography.
CAUTION: Filter Vignetting - As its name implies, a wide angle lens has a wide field of view. With this in mind, if you add more than one filter to it, it begins to “see' the filter ring and puts dark corners in your image.
ANGLE OF VIEW - Also known as the "Field of view," "FOV" and the "Angle of the field of view", it is the extent of the view taken in by a lens. The focal length of a lens, in conjunction with film size, determines the angle of view.
In fact, usually, it will strike well outside your lens's field of view, thus rendering a frame empty of any lightning. This can be quite frustrating, which is why I recommend lots of patience.
On your XS, the 50mm lenses have the same field of view as an 80mm lens would on a 35mm or full-frame camera. That's a "mild telephoto" or "portrait" length, but it's still very useful.
Parallax: The difference between the field of view seen through a camera's viewfinder and the image recorded on film by the taking lens of a twin lens reflex camera.
SHORT Depth of Field refers to a narrow field of view that is in focus. When objects in the foreground, mid-ground OR background are exclusively in focus, this is referred to as short depth of field.
Equivalent Focal Length - The focal length of a given lens expressed in terms of the field of view that length would give in a 35mm camera. This allows lenses for different camera designs to be expressed in terms of their real-world field of view.
Fixed Lens has one set focal length with a specific field of view which cannot be changed. Any camera without varifocal option has a fixed focus lens.
But it's more than price: The Alpha 900 is the first full-framer with anti-shake tech and a bright, big honkin' 100% field of view through the viewfinder.
Focal length of 50mm is popular because the field of view that's in focus is approximately what you see in the real world. There is no distortion of space like in ultra wide angle lens, and it is not compressed like telephoto lens.
A focal length sets the field of view your camera offers and is dependent on the camera lens. Low end cameras give you one choice. If you want the subject to be bigger or smaller, you will need to physically move closer or further from your subject.
Besides the focusing patch, RF viewfinder also shows framelines that delineate area that corresponds to field of view covered by lens.
The advantage of using the right eye (which feels more comfortable to most of us anyway), is that the left eye is not blocked by the camera body and you can, if you want, keep it open to see what is going on outside of your field of view.
VFOV noun
vertical field of view, usually expressed in degrees
wide angle converter noun
an adaptor that reduces the focal length of another lens, increasing the field of view ...
This is expressed in millimeters and represents the field of view of a camera lens. It is the distance between the focal plane and the rear nodal point of the lens, at infinity focus. For example, a 50mm lens has a wider view than a 100mm lens.
RGB ...
First, avoid the camera LCD - look through the viewfinder with one eye and use the other eye to spot the subject crossing the camera's field of view.
These devices define the field of view that will appear on your picture, and so let you compose your photo with great accuracy. Also, any close-up frame or pointer will show you precisely the plane of focus of the system.
Their unique curvilinear perspective and very wide field of view demand your attention.
Normal Lens A lens that makes the image in a photograph appear in perspective similar to that of the original scene. A normal lens has a shorter focal length and a wider field of view than a telephoto lens, ...
Lens, Wide-Angle
A lens that has a shorter focal length and a wider field of view. See also Focal Length.
Lens, Zoom
A lens in which you adjust the focal length over a wide range. In effect, this gives you lenses of many focal lengths.
A full-frame sensor is one with approximately the same dimensions as a frame of 35mm film. Unlike the smaller, cropped sensors, there is no field of view multiplier so a lens has the same field of view as it would on a film camera.
Wide-Angle Lens - A lens that has a shorter focal length and a wider field of view (includes more subject area) than a normal lens.
Weatherproof Camera - Cameras that are moisture-resistant (but not waterproof) for safe use in wet conditions.
You can use a slower shutter speed to stop action that's moving directly toward or away from you than you can to stop action moving across your field of view.
Focal Length: Describes the magnification and field of view of a cameras lens which is dependent on the size of the imaging sensor used.
In close-up photography, the optical viewfinder being offset from the taking lens, does not "see" exactly the same field of view, often resulting in a subject being partly cut off.
What a digital lens would be equivalent to in terms of a 35mm film SLR camera. Used as a standard for discussing the field of view and magnification power of a lens.
A lens that captures a larger field of view than a normal or standard lens. For full frame digital SLRs a standard lens is 50mm, any lens with a shorter focal length is normally referred to as wide-angle.

Telephoto - A lens with a longer focal length and a smaller field of view than a standard primary camera lens. A telephoto is useful for enlarging distant subjects.
35mm Equivalency - This is what a digital lens equivalent would be as it pertains to a 35mm film SLR camera. The standard used for looking at the field of view and magnification of a lens.
A lens where the focal length is approximately equal to the diagonal of the film size it's being used for. This is also representative of the field of view of human sight.
This involves following the subject with the camera as it crosses your field of view, resulting in the subject being sharp and the rest of the shot being blurred, giving the feeling of movement to the subject.
On the other hand, the narrow field of view means that you can use deep hoods to very effectively cut out glare and reduce flare.
