Canon’s new EF8-15mm f/4L Fisheye USM zoom lens offers photographers the creative possibilities of shooting both circular and full frame images and CPN managed to grab the opportunity to shoot some footage with the lens attached to an EOS 5D Mark II DSLR showing it zooming from a circular fisheye image to a full frame fisheye.
On full frame cameras, such as the EOS 5D Mark II or the EOS-1Ds Mark III, the lens works as both a circular fisheye, where a circular image is projected back to the sensor, and a full frame fisheye where the scene fills the entire sensor.

When the EF8-15mm f/4L Fisheye USM zoom is used with EOS DSLRs with APS-C or APS-H sensors the lens produces a more traditional, full frame fisheye view. A zoom-lock mechanism on the lens body allows the range to be limited to the focal length that ensures the best full frame view that’s possible without unsightly edge vignetting. ‘C’ and ‘H’ markings are located next to the lens’ zoom operation ring, indicating the wideangle zoom position where vignette-free shooting is possible with either sensor; thus allowing photographers to achieve optimum results with any EOS body.

Canon successfully develops world's first APS-H-size CMOS image sensor to realize record-high resolution of 120 megapixels
TOKYO, August 24, 2010—Canon Inc. announced today that it has successfully developed an APS-H-size*1 CMOS image sensor that delivers an image resolution of approximately 120 megapixels (13,280 x 9,184 pixels), the world's highest level*2 of resolution for its size.
Compared with Canon's highest-resolution commercial CMOS sensor of the same size, comprising approximately 16.1 million pixels, the newly developed sensor features a pixel count that, at approximately 120 million pixels, is nearly 7.5 times larger and offers a 2.4-fold improvement in resolution.*3
With CMOS sensors, while high-speed readout for high pixel counts is achieved through parallel processing, an increase in parallel-processing signal counts can result in such problems as signal delays and minor deviations in timing. By modifying the method employed to control the readout circuit timing, Canon successfully achieved the high-speed readout of sensor signals. As a result, the new CMOS sensor makes possible a maximum output speed of approximately 9.5 frames per second, supporting the continuous shooting of ultra-high-resolution images.
Canon's newly developed CMOS sensor also incorporates a Full HD (1,920 x 1,080 pixels) video output capability. The sensor can output Full HD video from any approximately one-sixtieth-sized section of its total surface area.
Images captured with Canon's newly developed approximately 120-megapixel CMOS image sensor, even when cropped or digitally magnified, maintain higher levels of definition and clarity than ever before. Additionally, the sensor enables image confirmation across a wide image area, with Full HD video viewing of a select portion of the overall frame.
Through the further development of CMOS image sensors, Canon will break new ground in the world of image expression, targeting new still images that largely surpass those made possible with film, and video movies that capitalize on the unique merits of SLR cameras, namely their high mobility and the expressive power offered through interchangeable lenses.

Canon to exhibit two new telephoto lenses under development
TOKYO, August 26, 2010 — Canon Inc. announced today that it is developing two new telephoto lenses for use with its EOS lineup of single-lens reflex cameras — the EF500mm f/4L IS II USM and EF600mm f/4L IS II USM — and will display prototypes at the photokina 2010 photography and imaging industry trade fair between September 21 and 26 in Cologne, Germany.
The EF500mm f/4L IS II USM and EF600mm f/4L IS II USM are being developed as L (Luxury)-series lenses equipped with a high-performance image stabilization system. Employing fluorite and other special optical materials to correct for a variety of aberrations, the lenses aim to realize high-resolution, high-contrast imaging performance in a lighter-weight body design.
The EF500mm f/4L IS II USM and EF600mm f/4L IS II USM are under development as successors to the EF500mm f/4L IS USM (introduced in July 1999) and EF600mm f/4L IS USM (introduced in September 1999), respectively, models which earned strong praise from professionals in the field. The new lenses target improved dust-proof and moisture-proof performance in the face of harsh shooting conditions to satisfy the demands of sports, news and nature photographers, as well as high-contrast, high-resolution imaging from the maximum aperture setting.
Canon will continue to actively and flexibly respond to the diverse needs of professional and advanced-amateur users, expanding and improving the performance of its EF lens lineup to contribute to expanding the realm of photographic possibilities for SLR cameras.
Note: Details regarding release dates and specifications for the abovementioned products have yet to be decided.

New Lens Features
In addition to an anti-reflection multi-coating, the front and rear elements of all newly announced EF lenses and extenders are treated with Canon's new fluorine anti-smear lens coating. The fluorine layer is highly oil- and water-repellent so that any oil smears or water droplets on the lens can be wiped off quickly and easily without the aid of solvents using a soft dry cloth. These four new lenses and two new extenders are the first of their type to employ fluorine coating, and it is expected that this new feature will enhance the usability of the lenses during adverse shooting conditions.
The new Series II EF super-telephoto lenses can correct camera shake up to four full shutter speed steps, compared to two shutter speed steps for the original versions. This improvement is made possible by a new low-friction stabilizer mechanism that is not only more efficient than the previous design but also smaller and lighter. Other enhancements to the IS systems of both new super telephoto lenses have enabled quieter operation ideal for use during video capture.
Providing professional sports and wildlife photographers with greater tracking flexibility, Canon has introduced a third Image Stabilization mode option to its new EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM lenses. When mode 3 is selected on the lens, the image stabilization effect will not be seen in the viewfinder. When the shutter button is pressed halfway, the lens will begin detecting camera or lens movement and only during exposure, when the shutter is fully depressed, will the Image Stabilization engage and provide the equivalent of four stops faster compensation for blur-free images. The new Mode 3 is particularly useful when a photographer does not want to see the IS working in the viewfinder while tracking a moving subject.
Helping moviemakers achieve smoother and more appealing focus shifts when filming on EOS DSLR cameras, Canon has included a new Power Focus (PF) mode on the Company's two new super telephoto lenses. This mode allows manual rack focusing to be operated smoothly by turning a playback ring that is normally used for the focus preset function. Both low-speed and high-speed focus shifting are available.
Additionally, a new security slot attachment has been included on both new super-telephoto lenses to allow a wire-type security lock to be easily affixed, a great safety feature for professionals shooting from high vantage points above arenas and crowds.

NEW Canon EF 400mm f/2.8L IS II USM lens
Quintessential for many sports assignments including baseball, football, soccer and golf, Canon's professional 400mm f/2.8 lenses provide the light gathering capability and long telephoto reach that photographers need to freeze the action and fill the frame. The Canon EF 400mm f/2.8L IS II USM is the 5th generation in Canon's 400mm f/2.8 series and the successor to the current EF 400mm introduced in 1999. The new lens has been engineered for the ultimate in optical performance through the use of two fluorite lens elements for improved quality and reduced chromatic aberration. Helping photographers in the field, Canon has reduced the overall weight of the lens by a substantial 28 percent from 189.4 oz to 135.8 oz, making it Canon's lightest weight 400mm f/2.8 lens ever. The Image Stabilizer provides an equivalent of approximately four full shutter speed steps of shake compensation and has been enhanced through the incorporation of a rolling-ball-friction system in place of sliding parts in the compensation optics barrel for a minimum-friction structure. The overall durability of the lens has also been enhanced through increased usage of magnesium alloy and titanium for lens barrel components, together with weather sealing for all exterior joints and switches and a new fluorine anti-smear coating is applied to the front and rear elements.
The Canon EF 400mm f/2.8L IS USM lens is expected to be available in December for an approximate retail price of $11,000.
