Techniques Glossary FIXED FOCAL LENGTH LENS ...
A prime (fixed focal length) lens is set to one mm focal length. In other words, the focal length cannot be adjusted. If you want to get more or less of the scenery or object in the photograph, then you need to physically move yourself in or out.
FIXED FOCAL LENGTHS
Not all lenses zoom. Very long (400mm or longer) telephoto lenses, macro lenses and several other types are often fixed focal length.
FIXED FOCAL LENGTH - Descriptive of the lens in a camera that has one lens only that cannot be interchanged for another lens and that cannot be zoomed.
Fixed Focal Length. Basically a non zoom lens. 100mm, 50mm, 200mm etc.
Fixed Focal Length - A term that describes a non-zoom lens, it is fixed at a given focal length and is not variable.
Fixed focal length
When the camera's lens has a set focal length and cannot be moved so optical zooming is not possible.
Fixed focal length
Used to describe a camera with a non-removable, non-zoom lens. Because of this, the lens focal length cannot be changed.
Fixed focus
A camera where focus is not adjustable.
-Fixed focal length - camera system whose lens cannot be interchanged for a lens of different focal length.
-Fixed focus - lens camera system that has no method of focusing on a fixed point, usually at the hyperfocal distance.
Fixed Focal Length
Most digicams come with zoom lenses; those that don't are said to have a lens of fixed focal length.

A prime or fixed focal length telephoto lens offers maximum image quality, light gathering capability (aperture), and magnification. The good ones are big, heavy, and designed for use on a monopod or tripod.
Lens - Zoom or Fixed Focal Length: A zoom lens offers a number of angles of view in one lens. This is the most versatile choice.
Prime lenses have fixed focal lengths. While it may seem they are less versatile than zooms, they are often of superior optical quality, faster, lighter in weight, smaller in size and generally cheaper to buy.
I have the prime (fixed focal length) lenses because they are faster than the zooms-and actually cheaper. (The three primes cost, used, less than the 17-55mm f/2.8 IS lens does new.) I have considered getting the 17-55mm f/2.
Prime lenses have a fixed focal length (FFL) and large aperture and are favored by professionals, especially by photojournalists who often work in dim light, have no opportunity to introduce supplementary lighting, ...
Manufacturers are now producing wide to telephoto zooms that can rival fixed focal length and other zoom lenses. The newer 28-200mm and 28-300mm zooms are sharp, compact, and affordable.
Fixed Another factor to conisder is whether to get a fixed focal length lens, or a zoom lens. Fixed focal length lenses tend to produce better results, while zoom lenses offer more flexibility.
The Zoom - Digital point and shoots are still in their baby stages longevity wise but once upon a time most had a fixed focal length lens meaning there was no built in zoom.
Some cameras suffer more than others and in fixed focal length lenses the effect is less prominent than in zoom lenses. This form of distortion is brought about by the way modern zoom lenses are constructed and is dependent on the focal length used.

Back in the day when professional lenses were invariably fixed focal length, most lenses had just four elements and manufacturers sometimes tried to save money by paring this back to only three.
A Telephoto Lens has a long and fixed focal length (100-800mm). These long lenses enable you to compress a distance (and compress the sense of depth, as well) and pick out specific objects from far off.
Generally the fixed focal length lenses are no problem, but the zoom models start to get really limited in the size of the aperture.
my lovely 50mm prime A prime lens has a fixed focal length whereas a zoom lens has a variable focal length.
A prime lens has fixed focal length, which means you cannot zoom the motive closer or more distant. Instead you - the photographer, have to move closer to or more distant from the motive to get the framing you want.
Prime lenses have a fixed focal length. In order to fit more or less into the viewfinder, the photographer must physically move forward or backward. Focal length in a zoom lens can be changed by turning the zoom ring on the lens.
If you must buy a new lens, and this article rightly assumes that most lenses are sharp enough when used properly, then consider going for a prime lens (lens with a fixed focal length, meaning you cannot zoom). Lenses like 50mm f/1.
A question most lens buyers face - Should I buy a zoom lens or one or more fixed focal length (prime) lenses?. Experienced photographers who have been around for a while, often prefer prime (fixed focal length) camera lenses over zoom models.
A "normal lens" for a 35mm camera usually refers to a fixed focal length lens of 50mm or a zoom lens zoomed in a little from its widest angle. When using a lens of this focal length, the scene looks about the same as it does to the unaided eye.
The disadvantage is that sometimes they tend to be a little less sharp than fixed focal length lenses. This is especially true when the zoom range is large, like in a lens that’s 18-200mm.
If you've decided to take fixed focal length lenses, then all you probably need is a 20mm, 50mm and 85mm. The underlying philosophy is less is more.
You should probably avoid zoom lenses, they do not flat objects as well as fixed focal length lenses, and they often do not focus close enough. One inexpensive alternative is 50mm lens.
It's any lens that has a fixed focal length — like a 28mm or a 105mm or a 300mm. In it's simplest form, it's any lens that's not a zoom. What's the big advantage of a prime lens?
Zoom lenses have replaced the fixed focal length camera lens in most camera models, especially with the advent of digital cameras. When choosing camera lenses, bear in mind that an optical zoom lens and a digital zoom lens are different.
Considering 35mm film 24x36mm frame format, a fast lens with fixed focal length between 24mm and 135mm will typically have a maximum aperture of f2.5 or less. f2.
The Panasonic 8mm fisheye is a fixed focal length lens, where the Tokina is a zoom lens. When compared to the Tokina at 10mm, they both have the same 180 degree angle of view diagonally, and the same 35mm equivalent focal length.
Prime Lens - This is a lens with only one fixed focal length.
Profile - Detailed information about the color qualities in a digital camera, also referred to as a device profile or ICC profile.
Digital Zoom, as the 40i doesn't have any optical zoom (it's a fixed focal length lens), it has a partial substitution in a digital zoom mode which is only accessible in 1280 x 960 (up to 1.88 x) and 640 x 480 (up to 3.75 x) modes.
Housed cameras with dome ports accommodate fixed focal length wide-angles like the 18 or 20mm lenses, or even full frame fisheyes such as the 16mm.
Prime Lens
The opposite of a zoom lens, prime lenses have one fixed focal length. They represent the best quality of lens available, but have the big drawback in that they cannot 'zoom in' to a subject.
Zoom Lens A lens with a mechanical assembly of elements that permits the variance of the focal length and thus the angle of view, as opposed to a prime lens, which has a fixed focal length.
A number of cameras are fitted with lenses that go beyond the simple fixed focus, fixed focal length lenses of the budget cameras. The most common of these added features are:
Zoom lenses
Macro lenses
Interchangeable lenses ...
Macro lens: A primary lens that can be focused from a very short distance out to infinity. May be a fixed focal length lens or a zoom. However most high magnification Macro lenses (lifesize or higher) are fixed.
These are the opposite of zoom lenses in that they are fixed at one focal length (often called a fixed focal length lens.we're an inventive bunch aren't we!?).
Some lenses offer an adjustable zoom range, while others are of fixed focal length. Some lenses have a macro setting, for extreme close-up photography of objects just a few inches away.
There is also some loss in picture quality when compared to the performance of a fixed focal length lens. There are four basic types of wide to telephoto zoom lenses for 35mm cameras: Wide-range zoom lenses have focal lengths from about 28mm to 80mm.
