What is Canon 9-point AiAf...

AiAF ( knowns as Artificial Intelligence Auto Focus) automatically locates the closest subject in your photograph – even when it’s off-centre – and gives optimal focus to that area. With up to 9 points available, photos will have pin-sharp clarity whatever your composition where this function can be found at most of Canon D-slr..

But do know there is still other function on most Canon product such as..

FlexiZone AF/AE control gives you complete focusing flexibility. You manually select the focus point from almost anywhere in the frame by moving the auto focus window in the viewfinder. For even greater control, you can measure exposure at your chosen auto focus point or the central area of your shot.

Face Detection AF/AE where it achieve sharper, brighter people shots with Face Detection AF/AE. The camera automatically detects up to 9 faces in the frame and optimises focus and exposure accordingly although this function is available for most of the camera in the market..

Sigma Lenses Terms...

APO:APO or apochromatic lenses are made using a low dispersion glass to reduce chromatic aberration.
DG:A DG lens can be used with both 35mm SLR and digital SLR cameras. DG refers to additional optical coatings that are meant to minimize reflections of light off the sensor itself.
DC:A DC lens is designed so the image circle matches the smaller size of a digital SLR's image sensor compared to a 35mm frame. These are typically lighter than DG lenses but are not suitable for 35mm SLRs.
EX:An abbreviation for the "Excellence" range of lenses. These lenses are similar to Canon's L series (Canon's professional range of lenses).

Canon Speedlite Technologies

A-TTL
A-TTL is an acronym that stands for Advanced-Through The Lens flash metering. As with ordinary TTL flash exposure systems, a sensor inside the camera reads the amount of light being reflected off of the film during the exposure. When the sensor determines that the exposure is sufficient, it terminates the flash pulse. A-TTL, first seen on the T90 (which predates the EOS family), is a flash exposure system that adds a brief preflash during exposure metering when the camera is in the programmed exposure (P) mode. The amount of light returned from this preflash is used to determine an appropriate tradeoff between aperture and shutter speed in P mode. Depending on the specific flash unit and whether or not it is set to bounce, the preflash might be infrared or it might be the normal white flash. In an A-TTL system the sensor that reads the preflash return is located on the flash unit; this caused some issues especially when using filters as the filter would cover the lens (but not the sensor outside the lens) thus causing inaccurate settings. Some early Canon EOS cameras also used the A-TTL preflash in non-programmed exposure modes to detect "out of range" conditions; the "out of range" warning feature was dropped on later models, reportedly due to patent conflicts.

E-TTL
E-TTL (Evaluative-Through The Lens) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure. Unlike TTL and A-TTL metering, which use a dedicated flash metering sensor mounted in the base of the mirror box, E-TTL uses the same evaluative metering sensor used for ambient metering. Like TTL (and like the actual flash metering, but not the pre-flash, of A-TTL), the sensor is internal to the camera and takes its exposure via the lens so any filters added to the lens will also affect the E-TTL readings giving more accurate exposure information to the camera.
The pre-flash occurs immediately before the main flash (except when using the camera / flash in 2nd curtain synch mode) and is barely perceptible, although can be seen if you watch carefully for it. When using flash exposure lock (FEL), the pre-flash is fired when FEL is activated.

E-TTL II
Since the introduction of the EOS 1D Mark II Digital SLR camera, Canon introduced an improved TTL flash algorithm known as E-TTL II. Basically a software improvement on E-TTL, E-TTL II is body-dependent and therefore can use existing E-TTL flash units and EF lenses.
The main improvement of E-TTL II is that it gives a more natural flash exposure, by being able to handle tricky scenes where normally the old E-TTL system will be thrown off. Such improvements are possible because E-TTL II now incorporates lens-to-subject distance information in its calculation (where available) to assist in determining an approximate guide number for flash output. The flash metering system is also no longer linked to the AF system, where in the old E-TTL metering bias is given to the selected AF point. Rather, E-TTL II compares the ambient and the pre-flash light levels of the scene to determine where the subject lies. This gives the photographer flexibility to lock focus and recompose the scene without fooling the flash metering system. 'Hotspots' (areas of high reflectance) that will normally throw off the flash metering system are also ignored in the calculation.
E-TTL II is now a standard in all EOS cameras introduced with or after the Canon EOS-1D Mark II (2004).

Canon EF 1200mm lens

The Canon EF 1200mm f/5.6L lens is a professional EF lens made by Canon that was introduced in 1993, six years after the launch of EOS cameras, and discontinued in 2005. The initial price for this lens was US$89,579. It weighs more than 36 pounds (16 kg), comes with its own heavy-duty tripod and case, and was built only by request. The focal length can be increased to 1700 mm f/8 or 2400 mm f/11 using the Canon EF Extenders 1.4× and 2× respectively...James Jannard ( the billionaire founder of Oakley ) also own one of it as he was one of the keen photographer, he maintains a website of his own photographs, uses high-end canon equipment, including a 1DS camera.....


Technical data;

Lens construction: 13 elements in 10 groups (protective glass and drop-in filter included)
Diagonal angle of view: 2°-5°
Focus adjustment: Inner focusing system with USM
Closest focusing distance: 14m / 46ft
Filter size: 48mm rear drop in
