Manufacturer description

London, UK, 2 July 2013 – Canon today unveils an outstanding new addition to its world-famous EOS series – the EOS 70D. Designed for aspiring enthusiast photographers, the EOS 70D is the ideal camera for anyone looking to take their photography to the next level. It combines completely new, world-first Canon imaging technology with powerful, creative and wireless sharing features – delivering a responsive, all-purpose camera ideal for capturing the moment with stunning images and Full HD video.

Capture the moment with stills and Full HD movies

The EOS 70D features a new 20.2 MP APS-C CMOS sensor, designed and manufactured by Canon. It’s the first Digital SLR in the world to feature ground-breaking Dual Pixel CMOS AF technology, which delivers smooth and accurate autofocus (AF) when shooting Full HD movies and fast AF acquisition when shooting in Live View mode. Paired with the 14-bit DIGIC 5+ processor and 19-point all cross-type AF System, the EOS 70D captures incredible, full resolution images at up to 7 frames per second, with up to 65 JPEG or 16 RAW images in a single burst*. Additionally, a native ISO range of ISO 100-12800 enables photographers to shoot in lower light conditions and use faster shutter speeds whilst retaining high image quality.

“I was incredibly impressed with how many new technologies the EOS 70D packs into one body, and how versatile it is,” said Brutus Östling, Canon Ambassador. “The EOS 70D is the perfect camera for anyone that wants to develop their photography skills. Not only is it suited to shooting people, landscapes and action easily and in outstanding quality, but also filming subjects in Full HD with focus speeds I never thought would be possible. The camera proved itself in the most challenging of circumstances, and had a range of new-generation technologies to comfortably solve any test I threw at it – especially with the new Dual Pixel CMOS AF technology. It really takes DSLR shooting and filmmaking to a whole new level.”

Canon’s new Dual Pixel CMOS AF provides swift AF performance when shooting in Live View mode and smooth accurate focus for Full HD movies. It makes it easy for users to take their next step with movies, enabling them to keep moving subjects in sharp focus and create professional-looking pull-focus effects. The technology utilises advanced CMOS architecture, allowing two photodiodes to be mounted within each pixel, both of which can be read independently to achieve autofocus, or together for image capture, with maximum image quality at all times.

An advanced AF system for stills includes 19 cross-type AF points spread across the frame, providing high speed, accurate AF – ideal for tracking sports and wildlife subjects as they move within the frame. The AF system is customisable, allowing photographers to adapt to the subject they’re shooting. AF points can be used individually, together in small groups, or as a wide active area for more unpredictable subjects. A dedicated AF area selection button, positioned conveniently next to the shutter release, enables quick switching between modes, without having to take the camera away from the eye.

Expertly designed for professional control

The EOS 70D’s powerful specification is packed into an expertly-engineered body that’s designed for comfort and swift operation. The Intelligent Viewfinder, with 98 per cent frame coverage and 0.95x magnification, allows photographers to comfortably frame their images and visualise settings via the electronic overlay. Conveniently-placed controls provide instant access to the most frequently used settings, such as ISO, AF mode selection and metering, so users can quickly change settings and concentrate on capturing the moment.

A 7.7cm (3.0”) Vari-angle Clear View LCD II Touch screen with a sharp 1,040k dot resolution is ideal for video shooting, or composing images from unusual and creative angles. The screen is a capacitive type, which supports a series of multi-touch gestures including swiping and pinch-zooming – perfect for navigating menus, amending settings or flicking through images.

Clever connectivity for easy control and instant sharing

The EOS 70D is the latest EOS model to feature integrated Wi-Fi, providing the freedom to remotely control the camera, as well as share images. Using Wi-Fi connectivity, users can connect to the EOS Remote app and control a wide range of image settings, including ISO and exposure, as well as focus and release the shutter. Photographers can also remotely use Live View mode, as well as review and rate their images.

Instant creativity unleashed

The EOS 70D features a host of creative modes to make capturing unique images easy. In-camera HDR removes the challenges of shooting in tricky, high contrast situations, merging three exposures into one that captures more detail in both the shadow and highlight areas. With multiple-exposure mode, photographers can shoot and combine up to nine exposures into a single image, or use a range of Creative Filters to instantly change the style and look of their shot.

Experimenting with creative off-camera flash is easy, thanks to the Integrated Speedlite transmitter, which provides in-camera control of multiple Canon Speedlite EX flash units.

Creative Full HD Movies

Alongside beautiful stills, the EOS 70D allows photographers to create high quality movies with ease. Full HD (1920 x 1080p) resolution video can be captured with a choice of selectable frame rates, including 30, 25 or 24fps, and 60 and 50fps at 720p, and a range of compression options for post-editing and sharing. Thanks to new Dual Pixel CMOS AF, Movie Servo AF mode tracks subjects as they move, or even as shots are recomposed, ensuring they’re always in focus. Alternatively, users can select different focus areas over 80 per cent of the frame** simply by tapping the touch-screen, even when recording – ensuring that movies stay sharp and clear if a subject moves or the user changes the composition of a shot.

Videographers can also enjoy stereo sound using the internal microphone, or enhance audio with the in-built external microphone input terminal. Full control over settings such as aperture and ISO is also possible within manual mode, giving users greater freedom as their skills develop.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
