Press release:CANON U.S.A. ANNOUNCES NEW EOS REBEL DSLR CAMERAS FEATURING 24.2 MEGAPIXELS AND WIRELESS FUNCTIONALITYThe new EOS Rebel T6s and EOS Rebel T6i1 DSLR cameras combine affordability with workhorse imaging features and functionalityMELVILLE, N.Y., February 5, 2015 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the addition of two new DSLR cameras to its popular EOS Rebel lineup: the EOS Rebel T6s Digital SLR camera, and the EOS Rebel T6i Digital SLR camera. Featuring a newly developed 24.2 megapixel Canon CMOS imaging sensor, both cameras deliver the highest resolution available amongst EOS models with an APS-C format sensor. Additionally, the cameras feature built-in Wi-Fi® and NFC™ capabilities – a first for the Canon EOS Rebel system – making snapping and sharing high-quality, treasured images seamless.“The Canon EOS Rebel series is one of the most popular lines of DSLR cameras on the market, and we are proud to continue to innovate and upgrade this line with features such as wireless connectivity and improved image capture capabilities,” said Yuichi Ishizuka, president and COO, Canon U.S.A., Inc. “As the popularity of this line grows with consumers, we’re excited to launch the EOS Rebel T6s as our new flagship camera in the Rebel line, as well as have another budget-conscious offering in the line with the Rebel T6i.”With multiple features most commonly found in advanced amateur cameras, the EOS Rebel T6s is designed for photography enthusiasts, or those who are already experienced with entry-level cameras who want to take high-quality photos and videos, and look for more advanced features and functions. For more casual photography needs, or for users looking to purchase their first DSLR camera, the EOS Rebel T6i camera prioritizes affordability, without sacrificing basic SLR performance attributes like quick shutter response, and compatibility with Canon’s impressive line of interchangeable lenses and accessories.Outstanding Image Capture FeaturesThe new EOS Rebel cameras have an extensive ISO range of 100-12800 (expandable to 25600) to accommodate shooting situations ranging from bright sunny days at the beach to dimly lit indoor dance recitals. The high-performance DIGIC 6 image processor helps provide outstanding image quality and speed, so pictures are clear and sharp.Building on the image capture functionality of their predecessors, the EOS Rebel T6s and EOS Rebel T6i cameras feature Canon’s new Hybrid CMOS AF III image sensor-embedded autofocus system, which allows for high levels of speed and accuracy when capturing Full HD video or high-resolution photos in Live View. This is particularly useful when capturing children playing sports, or animals in the wild, when it’s imperative to get the shot at the exact moment action is happening. Helping photographers capture those special moments, the cameras have high-speed continuous shooting up to five frames-per-second (fps). For photographers who prefer to compose their images through a viewfinder, the new EOS Rebel T6s and EOS Rebel T6i cameras have a 19-point all cross-type AF system that allows for superb autofocus, as well as focus area selection modes.Brand-new to the EOS Rebel line, the cameras feature built-in wireless capabilities, which allow users to wirelessly transfer images and videos with ease to compatible smartphones and tablets through Canon’s newly updated and free Camera Connect app.2 Images and videos can also be shared wirelessly to a wide range of popular social networking sites through Canon iMAGE GATEWAY. 3 The camera’s built-in NFC (Near Field Communication)4 allows quick and simple pairing to a compatible Android device, or devices that support NFC like the new Canon Connect Station CS100 photo and video storage and sharing device. The built-in Wi-Fi functionality also allows users to wirelessly print their images to any compatible printer, like the PIXMA MG7520 or PIXMA iP8720.With an intuitive design that allows for an optimal photographic experience, the new EOS Rebel cameras have a three-inch Vari-Angle Touch Screen Clear View LCD monitor with approximately 1,040,000 dots. This design enables flexible positioning for high or low framed shots, as well as clear viewing even when outdoors in the sunlight. Additionally, the cameras feature the latest version of Canon’s EOS scene analysis system, which helps photographers capture beautiful images in a wider range of situations by detecting near-infrared light and flickering light sources. Also new to the entire EOS system, both models feature color tone detection, which helps ensure individuals in photographs are properly focused and/or exposed by adjusting both autofocus and exposure metering.Full HD Video CaptureThe EOS Rebel T6s and EOS Rebel T6i cameras feature EOS Movie mode which captures Full HD 1080p resolution video up to 30 fps in MP4 format for high quality shooting and easy movie sharing on select social networking sites. Manual exposure control, digital zoom and an external stereo microphone jack are provided for advanced users using the EOS Rebel T6s.Expanded Creative FunctionalityAllowing for full creative control, the new EOS Rebel cameras offer creative filters available as presets for photos and movies. These filters can be displayed in real time during Live View shooting, providing an easy way for users to enhance their creative work. Users can further expand their artistic abilities right from the camera with Creative Filters such as Fisheye Effect, Toy Camera Effect and Monochrome mode. Fisheye Effect gives images a panoramic look and feel, Toy Camera Effect adds a grainy look to soften photos, illustrating a vintage appearance and with Monochrome mode, photos can either have black-and-white, blue or sepia tones, to display a more classic appearance.Advanced Features & CapabilitiesFor photographers who desire more advanced features, the EOS Rebel T6s is the first EOS Rebel class DSLR camera to feature a top LCD panel, Quick Control Dial, Horizontal Level and built-in HDR movie capabilities. The new camera is also the first model in the EOS Rebel series to feature Servo AF in Live View, allowing continuous tracking of moving subjects during burst mode shooting sequences.AvailabilityThe EOS Rebel T6s Digital SLR camera and EOS Rebel T6i Digital SLR camera are scheduled to be available at the end of April 2015.
