The main markets for such long, fast lenses are wildlife and sports photographers.

These are fast lenses compared to other lens designs of similar focal length, but with somewhat less coverage.

A fast lens transmits more light and has a larger opening than a slow lens.

He retired from The Times 40 years later in the era of the 35-millimeter camera with high-speed shutters and large, fast lenses.

There was certainly nothing like what you can achieve with a fast lens and an SLR.

A fast lens (minimum F number of 2.0).

With 35 mm cameras, the fastest lenses are typically in the "normal lens" range near 50 mm.

This is too short for accurate focusing with lenses longer than 90mm and fast lenses used at full aperture.

However, there are several high-quality fast lenses available that are relatively inexpensive, particularly in normal lens focal lengths.

Very fast lenses used in x-ray machines:

This explains why in the early days of SLR development, camera makers raced to develop faster lenses.

Presently, he uses the models D3 and D700 and various fast lenses.

Teleconverters need a fast lens for fast, reliable autofocus.

Fast lenses are typically larger than slow lenses (for comparable focal length), and typically cost more.

Very fast lenses in D-mount for 8mm movie use on H8 cameras:

A greatly improved camera known as KH-3 first flew in August 1961 and featured a faster lens and finer focus.

The result was the Planar Series Ia of 1896, with maximum apertures up to f/3.5, one of the fastest lenses of its time.

In exceptional circumstances lenses can have even wider aperatures with f-numbers smaller than 1.0; see lens speed: fast lenses for a detailed list.

They marked the return to Victor Hasselblad's original desire to have a small camera with fast shutter speeds (1/2000 s) and fast lenses.

Previous G series models had featured a fast lens, Raw image format capture, and a tilt-and-swivel LCD.

Many very fast lenses exist in C-mount (such as used by CCTVs), including:

The G15 marked a return of the G series lens to the fast lens faster than that of even early G cameras.

Ed Di Giulio, who rebuilt the camera for Kubrick, says that it is two f-stops faster than even the fastest lenses currently available.

Carl Zeiss Vario-Sonnar lens with an aperture of f/2.0-f/2.4 which can be considered as a very fast lens in its class.

Sims' history as a cinematographer and the fact that nearly all of the film would be shot at night led to his insisting on using a sensitive camera with fast lenses.

The introduction of fast film changed the way a photographer must wait.

The candlelight was more than adequate, since I had brought fast film.

Strange as it might seem, a faster film may do better at the beach because its contrast is lower.

In other words, after two hours on screen, "Ripley" is still a very fast film.

It boils down to this: If you need the speed, then use a fast film.

The fast filming process he uses is a form of guerrilla film making.

It is the fourth fastest film to reach the milestone.

(It is natural for a faster film to require a longer first development time.

Faster films need larger grains of silver to form an image in less light.

This enables the camera to let in more light, giving it the equivalent of faster film speed.

If the room is large, he keeps his aperture at f/4 by switching to a faster film.

Graininess becomes more pronounced with faster film and the degree of enlargement.

It also became the fastest film to pass the $100 million mark, achieving the feat in just six days.

It was armed with fast film and a smart flash, which would fire only when the light was too low for the film's speed.

Fast films generally are not only more contrasty, they're also more grainy.

In general, faster film is more expensive.

A slow shutter speed, a bigger aperture, and a fast film will make a brighter picture.

One way to alleviate the problem is to shift to a faster film, which may allow the camera to take a picture even without the flash.

One can accept the blur as an artistic effect, or change to a faster film or add light from an electronic flash.

Unfortunately, however, some simple cameras are unable to register the speed of such a fast film, which negates its advantages.

"The light's not so good, but with fast film-" A startled scream caused the two boys to jerk their heads around.

Photographing subjects such as rapidly moving sports or in low-light conditions, a professional will choose a faster film.

In the end it acquired a total of $1,066,179,725 at the worldwide box office, becoming the third and fastest film to reach this amount.

If you want the scene to have more snap, however, try a faster film, which is likely to have more contrast built into it.

On the down side, faster film tends to produce prints with larger grain, giving a slightly more jagged appearance to the image.
