Unless you’re shooting a still life, fast focus is key to getting good photos—as I found out after taking a cardfull of blurry snaps at a dance party over the weekend.
And by its own admission, Olympus has been, er, not famous for the focus speed of digital SLR cameras and lenses. Olympus, famous for introducing technologies that competitors eventually copy, has developed several new tricks for the E3. Given my experience over the weekend, I’d have been happy to get the lens in focus within the diameter of a human finger.
Great to know the -- in depth from this blog.This will really help for my forward steps to be taken. My brother is very fond of photography, his birthday is coming soon and I am planning to gift him a professional video camera. Most of the optical and mechanical elements of a movie camera are present in the movie projector.
Double-system cameras are generally categorized as either "sync" or "non-sync." Sync cameras use crystal-controlled motors that ensure that film is advanced through the camera at a precise speed. To synchronize double-system footage, the clapper board which typically starts a take is used as a reference point for the editor to match the picture to the sound (provided the scene and take are also called out so that the editor knows which picture take goes with any given sound take). One of the first patented motion-picture film cameras was designed by Louis Le Prince in 1888. Georges Demeny, employee with Etienne Jules Marey, constructed the Beater Movement in 1893. In 1894 Polish inventor Kazimierz Proszyński constructed Pleograph projector and camera in one, and in 1898 most advanced biopleograf. Max Skladanowsky conceived his own make of camera in 1894-95, but more interesting is his “Bioscop” projector, the first duplex construction in practice. The Lumiere Domitor camera was originated by Charles Moisson, chief mechanic of the Lumiere works at Lyon in 1894.
In 1923 Eastman Kodak introduced a 16mm film stock, principally as a lower cost alternative to 35mm and several camera makers launched models to take advantage of the new market of amateur movie-makers.

The details you provide on this page will not be used to send unsolicited e-mail, and will not be sold to a 3rd party. But the company claims its new E3 model is the world’s fastest—from 33 to 200 percent faster than any competitors.
It starts with the autofocus chip, featuring 11 cross-shaped sensors, for a total of 44 data points.
A temperature sensor by the focusing chip allows the camera to determine how far the plastic mount has expanded or contracted, and adjust focus calculations accordingly. The video camera has largely replaced it for private use, but for professional purposes, movie cameras are used and produced today, especially for the production of full-feature movies.
The requirements for film tensioning, take-up, intermittent motion, loops, and rack positioning are almost identical.
More recent equipment often has done much to minimize these shortcomings, although access to the film movement block by both sides is precluded by basic motor and electronic design necessities. These two television and video systems also have different resolutions and color encodings. The films are projected simultaneously, either on a single three-image screen (Cinerama) or upon multiple screens forming a complete circle, with gaps between screens through which the projectors illuminate an opposite screen. Most film cameras do not record sound internally; instead, the sound is captured separately by a precision audio device (see double-system recording). A smaller balance stripe existed between the perforations and the edge to compensate the thickness of the recording stripe to keep the film wound evenly. In addition, they're designed to be quiet enough to not hamper sound recording of the scene being shot.
It also permits scene and take numbers and other essential information to be seen on the film itself. MOS cameras are also often used for second unit work or anything involving slow or fast-motion filming. One of the most complicated models is the Mitchell-Technicolor Beam Splitting Three-Strip Camera of 1932. Thought initially to be of inferior quality to 35mm, 16mm cameras continue to be manufactured today by the likes of Bolex, Arri and Aaton many in the Super 16mm and Ultra 16mm formats.

Olympus overlaid an identical set of sensors—creating a houndstooth pattern they call cross-lamination.
Instructions go to the new lenses which focus using “supersonic wave drive” motors that turn in increments as small as five microns—less than the diameter of a human red blood cell.
Like Canon (whose Rebel XTI SLR I was using), Olympus doesn’t put a focusing lamp on the E3.
In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; "frame".
The camera will not have an illumination source and will maintain its film stock in a light-tight enclosure. Many of the technical difficulties involving film and video concern translation between the different formats. The exceptions to this are the single-system news film cameras, which had either an optical—or later—magnetic recording head inside the camera.
Non-sync or "MOS" cameras do not offer these features; any attempt to match location sound to these cameras' footage will eventually result in "sync drift", and the noise they emit typically renders location sound recording useless. Aaton cameras have a system called AatonCode that can "jam sync" with a timecode-based audio recorder and prints a digital timecode directly on the edge of the film itself. Le Prince employed paper bands and celluloid film from John Carbutt and or Blair & Eastman in 1? inch width. It was apparently capable of taking up to ten photographs per second using perforated celluloid film.
With it, three colour separation originals are obtained behind a purple, a green, and a red light filter, the latter being part of one of the three different raw materials in use.

So if one set can’t lock on an exceptionally dark or smooth surface, the other set may pick up. For optical recording, the film only had a single perforation and the area where the other set of perforations would have been was exposed to a controlled bright light that would burn a waveform image that would later regulate the passage of light and playback the sound. However, the most commonly used system at the moment is unique identifier numbers exposed on the edge of the film by the film stock manufacturer (KeyKode is the name for Kodak's system).
The first motion picture camera patented in the United States was created by Thomas Alva Edison. A report on the camera was published in the British Photographic News on February 28, 1890.
This they covered with their own Etiquette-bleue emulsion, had it cut into strips and perforated.
The frames are later played back in a movie projector at a specific speed, called the frame rate (number of frames per second). Also, there is a rotating, sometimes mirrored shutter behind the lens, which alternately passes the light from the lens to the film, or reflects it into the viewfinder. These are then logged (usually by a computer editing system, but sometimes by hand) and recorded along with audio timecode during editing.

While viewing, a person's eyes and brain merge the separate pictures together to create the illusion of motion. In the case of no better alternative, a handclap can work if done clearly and properly, but often a quick tap on the microphone (provided it is in frame for this gesture) is preferred.
Friese-Greene gave a public demonstration in 1890 but the low frame rate combined with the device's apparent unreliability failed to make an impression.

    You both make it so easy to be taught even for those who're an off-the-cuff photographer, you may have to attend.
