Canon EF 28-135mm f/3.5-5.6 IS USM Lens Specifications

Product Description:
Explore Photography. Canon's new EOS 50D Digital SLR Camera Canon's new EOS 50D bridges the gap between the novice and the seasoned pro with a perfect combination of high-speed and quality. It features an APS-C sized 15.1-megapixel CMOS sensor for tremendous images, new DIGIC 4 Image Processor for fine detail and superior color reproduction, and improved ISO capabilities up to 12800 for uncompromised shooting even in the dimmest situations. It features a refined 3.0-inch Clear View LCD (920,000 dots) monitor, supercharged Live View Function with Face Detection Live mode, plus a number of new automatic Image Correction settings and HDMI output for viewing images on an HDTV. Pick up the EOS 50D and you'll experience true digital inspiration! Improved Image Quality The EOS 50D Digital SLR camera's 15.1-megapixel CMOS APS-C size image sensor has been improved thanks to the use of newly designed gapless microlenses over each pixel to reduce noise and expand sensitivity up to ISO 12800. The faster processing speed of the camera's DIGIC 4 image processor contributes to the fast 6.3 frame-per-second (fps) continuous shooting capability (for bursts of up to 90 Large/Fine JPEGs or 16 RAW images on a UDMA CF card), to give shooters the tools they need to capture that perfect moment in perfect clarity. The Canon EOS 50D camera provides ISO speeds from ISO 100 up to ISO 3200 in 1/3-stop increments, along with two high-speed settings - H1 and H2 - of ISO 6400 and ISO 12800, respectively. Along with a wide ISO range, Canon gives shooters more tools to help maximize clarity and color. The EOS 50D Digital SLR camera offers multiple levels of noise reduction during high-speed shooting. Users can choose from one of four settings- Standard/Weak/Strong/None - to help reduce digital noise that can result from poor lighting conditions. As part of the camera's internal image processing, the Canon EOS 50D Digital SLR camera conducts peripheral illumination correction, which automatically evens brightness across the image field, making an image of a blue sky even toned throughout, a function previously accomplished through post-processing software on a personal computer. Thanks largely to the DIGIC 4 processor, this automatic adjustment can be made in-camera during shooting with JPEG images or corrected in post-photoshoot processing with RAW images through Canon's Digital Photo Professional (DPP) software, which is supplied at no extra charge. Helping to ensure each picture's subject is clearly visible, Canon's enhanced Auto Lighting Optimizer analyzes the brightness of subjects and automatically adjusts dark images so that they appear brighter, perfect for subjects in shade or in backlit situations. The Auto Lighting Optimizer on the EOS 50D Digital SLR camera has been updated not only to optimize images while they are being taken, but can also optimize images post-capture, during playback, to help ensure the subject of each image does not appear too dark. This is especially helpful when an amateur photographer uses the camera, because post-capture enhancement can help maximize image quality without the need of a computer. A significant upgrade to the Canon EOS 50D camera is its large, clear 3.0-inch Clear View LCD screen which features 920,000 dot/VGA resolution, four times the pixel count of the EOS 40D camera's screen, for better clarity and color. To help show off those fantastic shots, the EOS 50D camera includes an HDMI (High-Definition Multimedia Interface) output to display crisp, clear images on a High-Definition TV. The EOS 50D recognizes the needs of today's photographers, and the faster processing speed of the DIGIC 4 processor helps support UDMA cards for faster writing of image files. The camera is also equipped with a high-performance viewfinder featuring 0.95x magnification and the same high-performance Autofocus (AF) system as the EOS 40D camera with nine cross-type sensors for accurate target subject acquisition with lenses possessing maximum apertures of f/5.6 or faster and a high-precision diagonal center cross-type AF point that's effective with f/2.8 and faster lenses, helping photographers ensure better focus of their targets. The AF Microadjustment feature, originally introduced last year with the Canon EOS-1D Mark III professional digital SLR camera, has also been added to the EOS 50D for maximum control over focusing precision. Canon EF 28-135mm f/3.5-5.6 IS USM Zoom Lens Standard zoom lens with an Image Stabilizer and high zoom ratio. With the Image Stabilizer turned on, you can obtain sharp, natural-looking pictures in dim lighting without using flash or a tripod. Very handy for places where flash is prohibited. Uses ring-type USM for swift, silent autofocus and full-time manual focus. Closest focusing distance is 20 in. (50cm). Canon Gets Creative For Advancing Amateurs Canon is taking steps to give advanced amateurs more flexibility with a new CA Creative Full Auto setting on the EOS 50D Digital SLR camera's mode dial. This new setting goes a step beyond Full Auto, by allowing users to make adjustments before shooting while still in an Automatic mode, without needing to know the meaning of technical terms such as aperture, shutter speed, etc. In this mode, the camera menu on the back screen spells out options in common language for average photo enthusiasts, allowing them to blur the background or lighten or darken the image. These easy-to-comprehend image options will help amateur photographers improve the shots they are capable of taking, while helping them learn new techniques. When in the new CA mode, users will be able to adjust flash settings, brighten or darken images, blur the background, set the camera's drive mode, and select a picture style directly on the camera's LCD screen. Better Live View For photographers who prefer to frame their shots using the camera's 3.0-inch Clear View LCD screen, Canon has improved the Live View function of the EOS 50D Digital SLR camera to include Quick Mode AF, Live Mode AF, and Face Detection Live Mode AF that detects up to 35 individual forward-looking faces for better focus and clarity when taking group or portrait shots. The camera's Quick Mode AF setting flips the mirror down and carries out regular phase-detection autofocus, while the Live Mode AF and Face Detection Live Mode AF use the camera's CMOS image sensor for contrast detection autofocus. Two detailed grid displays have also been added to Live View shooting as optional settings for easier composition. Two Small RAW Formats In addition to the RAW and JPEG image capture modes that photographers are accustomed to, the EOS 50D Digital SLR camera now offers more manageable resolution settings and file sizes with two sRAW recording formats, sRAW1 and sRAW2. At the sRAW1 setting, resolution is 7.1 megapixels with a file size that is approximately 25 percent smaller than a standard 15.1 megapixel RAW image. With the sRAW2 setting, resolution is 3.8 megapixels at less than half the file size of a standard RAW image, retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images. The EOS 50D is the first Canon Digital SLR that allows the use of RAW and sRAW settings in Basic Zone as well as Creative Zone shooting modes, even further improving the camera's flexibility. EOS Integrated Cleaning System The Self-Cleaning Sensor Unit for the Canon EOS 50D has also been upgraded and now includes a fluorine coating on the low-pass filter for better dust resistance. The Self-Cleaning Sensor Unit uses ultrasonic vibrations to shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. The second part of the system includes a software component where sensor spots are mapped and saved as Dust Delete Data that is attached to the image file for removal during post processing using Canon's DPP software. Availability: The EOS 50D is compatible with the full lineup of Canon EF lenses as well as the affordable EF-S lenses created specifically for Canon Digital SLRs with APS-C size image sensors. The Canon EOS 50D Digital SLR camera is scheduled for October 2008 Delivery.
