Canon announced two new versions of its coveted Wide Angle Lenses and a new version of its popular 24-70mm Standard Zoom Lens for professionals and photo enthusiasts. The new EF 24-70mm f/2.8L II USM, EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM lenses use a rear focusing system, high-speed CPU, and a powerful ring-type Ultra Sonic Motor (USM) with optimized AF algorithms for faster auto focusing and sharp images. With large apertures these new lenses deliver beautiful, soft backgrounds for superior image quality. Canon EF 24-70mm f/2.8L II USM Lens for Harsh and Rigorous Conditions This new version of one of Canon's most popular lenses utilizes one Super UD lens element and two UD lens elements to help achieve outstanding image quality throughout the full zoom range. The result is significantly reduced chromatic aberration in the outer area at wide-angle, high resolution and contrast in images and crisp clear edges around the subject. The lens coatings have been optimized to ensure exceptional color balance while minimizing ghosting, and reduced spherical aberration. With a circular nine-blade diaphragm, the lens delivers soft backgrounds and incredible bokeh. In demand by architectural, corporate, adventure and professional photographers of nearly every discipline, the EF 24-70mm f/2.8L II USM lens combines amazing image quality with enhanced durability. Highly resistant to dust and water, the new lens has enhanced durability and weather sealing. The lens also features a zoom lock lever to secure the zoom position for safe transport, and fluorine coatings on the front and rear glass surfaces to reduce smears and fingerprints, making it an ideal lens regardless of the conditions. Newest Lenses Canon Lenses Canon SLR Cameras Canon Standard Prime Lenses with Optical Image Stabilizer: EF 24mm f/2.8 IS USM & EF 28mm f/2.8 IS USM Empowering landscape and wide-angle photographers with improved optical performance, Canon has upgraded both its EF 24mm and EF 28mm lenses with Image Stabilization technology and Ultrasonic Motor-powered auto focus. Both lenses feature Canon's Optical Image Stabilizer technology providing up to four shutter speed stops of correction. With the Optical Image Stabilizer turned on, photographers can capture sharp wide-angle images in low-light settings reducing the need for a flash or a tripod. New aspherical lens elements improve the peripheral image quality and a seven-blade circular diaphragm delivers beautiful, soft backgrounds. The silent and smooth operation of each lens makes them ideal choices for shooting video as well. The EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM lenses each have a minimum focusing distances of 0.20m and 0.23m, respectively. Price and Availability Canon EF 28mm f/2.8 IS USM lens will be available June 2012 for $799.99 Canon EF 24mm f/2.8 IS USM lens will be available June 2012 for $849.99 Canon EF 24-70mm f/2.8L II USM lens will be available April 2012 for $2,299

Novi Canonov EF 24mm f/1.4L II USM [napisao Gand. 24 Rujna 2008.][vijest pročitana 673 puta] Canon je obogatio svoju liniju objektiva iz serije EF predstavljanjem novog primarnog objektiva brze aperture: modela EF 24mm f/1.4L II USM, koji će zamijeniti model EF 24mm f/1.4L USM. Novi je objektiv u potpunosti iznova projektiran da bi poslužio kao zahtjevni parnjak Canonovim novim digitalnim SLR-ovima iz serije EOS, modelima EOS 50D i EOS 5D Mark II. EF 24mm f/1.4L II USM nudi: • brzu aperturu od 1/4 • asferične i UD elemente leće za korekciju kromatske aberacije • SWC premaz kojim se osjetno ublažavaju popratne slike i odbljesci • kružnu aperturu koja proizvodi ugodan bokeh • USM za potpuno ručno fokusiranje • bezolovno staklo (usklađeno s direktivom RoHS) • poklopac za objektiv i torbicu kao standardnu opremu Vrhunske slikovne performanse Objektiv EF 24mm f/1.4L II USM sastoji se od trinaest elemenata i deset grupa te je projektiran za dostizanje najviših standarda kvalitete slike. Dvije visokoprecizne GMo asferične leće koriste se za korekciju raznih aberacija, npr. zakrivljenja polja i iskrivljenja, a pomični mehanizam jamči oštre detalje u čitavom kadru duž cjelokupnog raspona žarišnih duljina. Osim toga, dvije UD leće smanjuju kromatsku aberaciju čestu u širokokutnim objektivima. Brza, iznimno velika maksimalna apertura od čak f/1,4 omogućuje izvrsne performanse u uvjetima slabe osvijetljenosti, a kružna apertura nudi mogućnost kreativnog naglašavanja pojedinosti koje nisu u žarištu. Žarišna duljina od 24 mm i USM žarišni motor koji omogućuje potpuno ručno fokusiranje čine objektiv EF 24mm f/1.4L II USM idealnim za situacije u kojima je potrebno koristiti širokokutan objektiv visokih performansi. Napredan premaz za leću Refleksija od slikovnog senzora na digitalnom fotoaparatu može smanjiti kvalitetu fotografija zbog pojave popratnih slika i odbljesaka. Da bi se smanjio taj učinak, unutrašnjost prednjeg elementa objektiva EF 24mm f/1.4L II USM premazana je Canonovim novim SWC premazom. Taj je antirefleksivan premaz osmišljen posebno za Canonove optičke uređaje, a pridonosi smanjenju pojave popratnih slika i odbljesaka, zahvaljujući čemu se dobivaju oštre, neiskrivljene slike. Robusna kvaliteta Objektiv EF 24mm f/1.4L II USM projektiran je da izdrži i najrigoroznije uvjete snimanja – zahvaljujući Canonovoj naprednoj hermetičkoj zaštiti od loših vremenskih uvjeta i prašine, taj je objekti savršen izbor za fotoreportere i fotografe koji se bave snimanjem pejzaža.
