Wide-Angle-to-Telephoto EF28-300mm f/3.5-5.6L IS USM Lens & Compact EF70-300mm f/4.5-5.6 DO IS USM Zoom Add Faster AF and Enhanced Image Stabilization to the Imaging Mix
MISSISSAUGA, Ont., Jan. 30 — Canon Canada Inc. has introduced the two newest members of Canon's EF lens line. The new lenses are designed for professional photographers and amateur enthusiasts. The 11x zoom ranges from a true wide angle 28mm to an ultra-telephoto 300mm while the company's newest compact Diffractive Optics lens offers 70 to 300mm zoom in a compact package.
The new EF28-300mm f/3.5-5.6L IS USM is an entirely new L-series design lens (and a significantly enhanced successor to Canon's EF35-350mm f/3.5-5.6L USM zoom introduced 11 years ago). It offers 11x zoom capabilities (compared with the 10x capability of its predecessor), and a 22-element L-series lens with faster autofocus and an Image Stabilization system.
The EF28-300mm f/3.5-5.6L IS USM lens that features three ultra low dispersion glass elements that reduce chromatic aberration, and three aspherical elements that reduce linear distortion and correct spherical aberration during zooming (keeping image resolution and contrast high) and minimize reflection, especially when used with digital SLRs. The shorter minimum focal length of the new lens versus the previous 35 to 350mm model also makes the EF28-300mm L zoom more suitable for digital SLRs with image sensors smaller than 35mm format.
The lens is compatible with optional EF12/EF12II Extension Tubes at all focal lengths and EF25/EF25II at mid-range and telephoto zoom settings. The EF25 provides a maximum magnification of 0.5x, effectively filling the frame with a subject approximately 5 by 7.6 cm at the 300mm zoom setting. It is also compatible with the 77mm 500D and 500 Close-up lenses for a maximum magnification of 0.58x.
The EF28-300mm f/3.5-5.6L IS USM lens kit includes a newly designed bayonet mount lens hood, a detachable tripod collar and a soft lens case.
Available in April, the EF28-300mm f/3.5-5.6L IS USM and the EF70-300mm f/4.5-5.6 DO IS USM lenses are priced at of $4,500 and $2,250 (Cdn. List) respectively.
In a separate announcement, Canon Canada Inc. has also released its newest professional digital SLR: the high-resolution, high-speed EOS-1D Mark II camera.
Its new 8.2-million pixel CMOS sensor, faster DIGIC II imaging engine and ability to capture eight-megapixel JPEG images at 8.5 fps in continuous bursts of up to 40 frames and RAW images in continuous bursts of up to 20 frames — with Canon technology's use of DDR SDRAM — make the EOS-1D Mark II the world's fastest pro-digital SLR camera. Designed for conditions in the field, on the sidelines or in the studio, the Mark II camera's exterior and chassis are constructed of a weather-resistant magnesium alloy. Its shutter is durability-tested to 200,000 exposures (50,000 more than on the EOS-1D), the body is highly weather-resistant with more than 70 gaskets and seals, and the camera's lens mount is made of stainless steel (and is fully compatible with all Canon EF, TS-E and MP-E lenses).
At the heart of the advancements provided by the EOS-1D Mark II camera is its extra-large, high-resolution, Canon-designed and produced 8.2 megapixel CMOS sensor. Measuring 28.7 by 19.1mm and 34.5mm on the diagonal, the CMOS sensor is comprised of 3520 by 2336 recording pixels, each 8.2 microns square, featuring primary RGB filtration and, like its predecessor the EOS-1D, has a 35mm focal length conversion factor of only 1.3x. The EOS-1D Mark II is equipped with the DIGIC II image processor, which permits faster processing of large files with superior colour rendering and more precise detail. This new DIGIC II chip is twice as fast as the image processor used in the EOS-1D and four times faster than the DIGIC chip in the EOS 10D and EOS Digital Rebel.
Set for release in April, the EOS-1D Mark II digital camera carries a manufacturer's suggested list price of $ 6,800 (Cdn.).更多精彩文章及讨论，请光临枫下论坛 rolia.net
