OM SYSTEM OLYMPUS 11-22mm f/2.8-3.5 Zuiko Zoom Lens for 4/3 Cameras

Product Description Compact lightweight wide-angle zoom lens with bright f/2.8 – 3.5 aperture With exceptional image quality, this compact and lightweight wide-angle zoom lens is perfect for capturing the feeling of the great outdoors or making a small room look more spacious. High-quality lenses, aspherical lens elements and coatings ensure outstanding optical performance and offer the professional an optimal complement to their Olympus E-System accessories. Micro Thirds System The Four Thirds System is a new standard that allows the full potential of digital photography to be exploited. The light is directed almost linearly to the surface of the image sensor for optimal images that are sharp and clear to the edges. The lens port is also standardized, so you can combine compatible lenses and cameras as you like without being fixed to a single manufacturer. The Four Thirds System makes any photographic application more exciting and powerful. Benefits of the Four Thirds System: 100% digital concept. Designed specifically for digital photography optimizes the performance of the image sensor. High mobility Compact design maximizes camera mobility. Open standard Ensures the expandability and compatibility of products from different manufacturers. Worse image quality when using an analog 35mm lens with a D-SLR camera The biggest problems that ordinary digital SLR cameras have struggled with are the decrease in image quality towards the edges of the frame, as well as the appearance of ghosting and backlight reflections on the surface of the image sensor that are thrown back onto the lens. The angle and aperture value were the same in both photographs, but one was taken with a conventional 35 mm lens, the other with a Four Thirds lens. When comparing the two images, shooting with the 35 mm film camera lens clearly shows back light reflexes and ghosting, as well as asymmetry reflections in the edge area and a general lack of sharpness. Four Thirds lenses, on the other hand, are optimised for digital photography, so that consistently sharp images are possible from the centre of the image to the edge of the image with minimised ghosting and backlight reflections. With the Four Thirds system, image sensors can capture the light more accurately The image sensor in a digital camera is comparable to a deep fountain. You can't see your reason without bending over the edge. In the same way, light incident at an angle does not reach the image sensor (i.e. the bottom of the fountain). Since many of the current D-SLR cameras with interchangeable lenses use traditional 35mm lenses, they are highly susceptible to reduced sharpness, chromatic aberration and edge shadowing. This is especially true for wide-angle lenses, as oblique incidents from particularly large angles hits the edge areas. With the Four Thirds System, the diameter of the lens port is larger than the image sensor, and the lens design tailored to digital photography ensures that the light hits the image sensor right into the edge areas. The result is clear, sharp image reproduction across the entire image plane. The linear light guidance and high imaging performance are the most important features of the Four Thirds lenses. An open standard that offers both precise image quality optimised for digital photography and compact dimensions To maximize the performance of the image sensor, the camera must be designed so that the light itself strikes the edge areas of the image sensor surface. If using a sensor the size of a traditional 35mm or APS film, there is only one way to ensure that the light is directed to the sensor in a straight line: magnification of the optics. During the development of the Four Th irds system, special attention was paid to avoiding this problem and achieving an optimal balance between high image quality and compact size. The resulting 4/3 type sensor gave the Four Th irds system its name. The basis for the high image quality of the Four Thirds System is the lens connection, whose diameter is approximately twice the size of the image circle. This extra scope provides much more freedom when designing the lenses and ensures sharp, clear images. Despite the compact dimensions of the camera and lens, the light hits the image sensor even at the edges of the frame. The straight light path also contributes to an enormous improvement in image quality. The diagonal of the 4/3 type sensor is about half the size of a 35mm sensor. The focal length required to achieve a certain angle of view is only half the size of a 35 mm film camera. Therefore, the optical system can be significantly reduced. As the eff ective aperture can also be reduced without reducing brightness, the Four Th irds system allows the construction of much brighter lenses. Thanks to this combination of compactness and large aperture, the potential for lens development is virtually unlimited. In other words, the introduction of the 4/3 type sensor has made it possible to design lenses that not only outperform conventional lenses in terms of performance, but are also extremely compact and easy to carry. For example, a Four Thirds lens with a focal length of 150 mm achieves the magnification power of a 300 mm lens in 35 mm format. And while traditional lenses of this focal length the maximum brightness was 1:2.8, the Four Thirds lens offers a f/2.0 light intensity. The Four Th irds system is therefore the ideal D-SLR system. Thanks to the optimal ratio of the image sensor and lens connection, the Four Thirds System successfully combines high image quality and compact size. The Four Thirds System's potential is also expanded by exclusive software that supports all aspects of image creation – from exposure to editing to image data management. From the Manufacturer The Zuiko Digital 11-22 millimeter f2.8-3.5 features two aspherical glass lenses that minimize distortion, spherical aberration and "Koma" aberration. A new multi-coating process applied to the first two lenses helps remove ghosting and glare, problems often associated with wide-angle lenses. The 11-22 millimeter focusing system also utilizes a floating mechanism to deliver sharp, high contrast images up to the lens' closest focusing distance, 0.28 millimeter (11.02 inches) at any zoom setting. Zuiko digital specific lenses are designed specifically for digital capture with smart technology that delivers edge-to-edge sharpness with reduced distortion and shading. The lenses are designed to perfectly match the imager so light strikes the sensor directly, ensuring rich, accurate colors, sharp contrasts, and bright images even at the edges. Zuiko digital specific lenses deliver higher resolutions, faster aperture speeds and focusing, and more compact sizes than equivalent 35 millimeter lenses. Zuiko digital specific lenses are based on the new FourThirds System, an open standard for digital SLR cameras and interchangeable lens systems that utilize a 4/3-type image sensor. The FourThirds System is designed to achieve an optimal balance between image quality, camera and lens size, and system expandability. The system maximizes the performance of image sensors and lenses with a 100 percent digital-from-the-ground-up design.
