Canon Introduces the First Camera Lens Featuring Hybrid Image Stabilization Canon U.S.A., Inc., continues its advancement of EOS lens technology with the introduction of three new EF and EF-S lenses: - EF 100mm f/2.8L Macro IS USM The new EF 100mm f/2.8L Macro IS lens is the world’s first camera lens featuring Canon’s new Hybrid Image Stabilization (Hybrid IS) technology*, compensating for both angle camera shake and shift camera shake, up to four shutter speed steps. The EF 100mm f/2.8L Macro IS USM lens is compatible with all EOS cameras, while the EF-S 15-85mm and EF-S 18-135mm zoom lenses are designed specifically for Canon digital cameras that are compatible with EF-S lenses.** EF 100mm f/2.8L Macro IS USM lens The EF 100mm f/2.8L Macro IS USM lens could very well be the essential multipurpose lens for every camera bag due to its ability to capture sharp close-up images of small objects as well as beautiful portrait-length telephoto shots. The incorporation of Canon’s new Hybrid IS in this L-series macro lens allows it to compensate more effectively for camera shake during close-up shooting and marks a significant improvement for professionals and advanced amateurs utilizing macro photography for portrait, nature or wedding shoots. New Hybrid IS Technology: Designed Especially for Macro Photography The world’s first* optical image stabilizer for SLR cameras was introduced in the EF 75-300mm f/4-5.6 IS USM in 1995. Since then, Canon has made continual advancements in IS systems to enhance panning capability and improve compensation for camera shake. Now, in a move aimed at extending image stabilization to the macro realm, Canon introduces its Hybrid IS in the new EF 100mm f/2.8L Macro IS USM — another first for Canon and the world. Conventional image stabilization technology is useful for reducing the effects of camera shake in non-macro shooting situations. When shooting handheld close-ups at 1x, however, camera shake makes it difficult to achieve acceptable results even with lenses incorporating conventional image stabilizers. Now, thanks to the Hybrid IS found in the EF 100mm f/2.8L Macro IS USM, Canon extends IS technology to the macro realm, making it easy to obtain clear handheld close-ups — a world first* and a definite advantage in environments where use of a tripod is not an option. In order to combat the effects of camera shake in a macro lens, the IS system must be able to compensate for both angular camera shake and shift camera shake — problems that become more apparent as magnification increases. The effects of shift camera shake are rarely noticeable when shooting outside the macro realm, such as in landscape photography. But when shooting extreme close-ups, even the slightest amount of camera shake, either of the angular or shift variety, can adversely affect image quality. In macro photography, shift camera shake and angular camera shake affect both the image formed on the sensor and the image shown in the viewfinder. This is especially relevant to handheld shooting at 1x, since the inability to properly compose and focus due to a shaky image in the viewfinder makes it extremely difficult to record sharp images. Conventional image stabilizers of the type found in Canon IS lenses incorporate an angular velocity sensor (vibration gyro) to compensate for angular camera shake. Based on the amount of camera shake detected by the sensor, the IS system calculates the amount of blur on the image plane, after which lens elements in the IS are positioned to compensate for the shake. However, this type of image stabilizer can neither detect nor correct shift camera shake common to handheld macro photography. The Hybrid IS includes an acceleration sensor in addition to the conventional angular velocity sensor (vibration gyro). Based on the amount of camera shake detected by the two sensors, a newly developed algorithm calculates the amount of blur on the image plane, after which lens elements in the IS are positioned to compensate for the two types of shake — a first in an interchangeable lens for SLR cameras and an excellent way to solve the problem of camera shake in macro photography. EF-S 15-85mm f/3.5-5.6 IS USM lens The versatile focal length, extreme wide angle and stunning image quality of Canon’s new EF-S 15-85mm f/3.5-5.6 IS USM lens makes this the ideal multipurpose wide-angle zoom lens for the photographer shooting a wedding or exotic vacation. Featuring three aspherical elements and one UD glass element for outstanding image quality, the zoom range of this lens is equivalent to 24-136mm on a full-frame camera. When coupled with Canon’s new EOS 7D DSLR, this lens provides moviemakers and videographers with a phenomenal focal range for wide-angle scenic footage and zoomed in telephoto shots. Canon’s new EF-S 18-135mm f/3.5-5.6 IS lens is the perfect Image Stabilized lens for advanced photographers looking for a wide-angle zoom lens with telephoto capabilities. Featuring a compact IS unit with shake correction up to four shutter speed steps, the zoom range of this lens is equivalent to 29-216mm on a full-frame camera.

Canon EF-S 18-200mm f/3.5-5.6 IS [napisao Gand. 6 Rujna 2008.][vijest pročitana 471 puta] Canon je obogatio svoju seriju objektiva EF-S svestranim novim modelom: objektivom EF-S 18-200mm f/3.5-5.6 IS. Taj objektiv nudi ekvivalentnu žarišnu duljinu od 29 do 320 mm i zum od 11x, što znači da je sada moguće koristiti samo taj snažan i lagan objektiv, bez potrebe za nošenjem više objektiva na snimanje. Objektiv EF-S 18-200mm f/3.5-5.6 IS namijenjen je korištenju isključivo s fotoaparatima EOS s postoljem za objektiv EF-S, što obuhvaća nove fotoaparate EOS 50D, EOS 1000D i EOS 450D te starije modele. Visokokvalitetna optika EF-S 18-200mm f/3.5-5.6 IS odlikuje se konstrukcijom koja se sastoji od šesnaest elemenata i dvanaest grupa. Njima su obuhvaćene i UD i asferične leće koje minimiziraju kromatske aberacije te jamče oštre detalje na čitavoj slici i pri svakom stupnju uvećanja. Podrška za žarišnu udaljenost od svega 45 cm fotografima pruža neograničenu fleksibilnost pri kadriranju. Optički stabilizator slike s četiri položaja brzine zatvarač Canonov optički stabilizator slike s četiri položaja brzine zatvarača, osmišljen posebno za specifični raspon žarišnih udaljenosti ovog objektiva, pridonosi smanjenju zamućenja slike koje se ponekad pojavljuje kada se snima bez stalka ili pri manjim brzinama zatvarača. Automatsko prepoznavanje panoramskih snimki jamči učinkovite performanse pri praćenju objekata u pokretu. Osim toga, budući da se IS sustav nalazi u objektivu, rezultati su vidljivi u tražilu tijekom kadriranja. Bez popratnih slika i odbljesaka Zbog odbijanja svjetlosti sa senzora za sliku na digitalnim fotoaparatima mogu se pojaviti popratne slike i odbljesci. Da bi se to spriječilo, na objektivu EF-S 18-200mm f/3.5-5.6 IS koriste se optički elementi premazani Canonovim patentiranim premazima Super Spectra te se tako dobivaju oštre, nedeformirane slike s prirodnom ravnotežom boja.
