For Canon EOS film and digital SLR cameras.
This lens features a fast f/2.8 Maximum Aperture and Canon's latest optical Image Stabilizer technology, providing up to 3-stop compensation for image blur caused by camera shake and slow shutter speeds. This ensures clear, crisp images, and makes handheld photography possible in more low-light situations than ever before.
Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. Features three aspherical lens elements (two types) as well as a Super-UD glass element for high image quality at all focal lengths. Ring-type USM provides ultra-quite, super-fast, precision auto focusing and predictive tracking. Inner Focusing and new AF algorithms, with full-time mechanical manual focusing. Produce brilliant out-of-focus characteristics with the circular aperture. (less)
Superb Autofocus - The lens' USM motor employs ultra-sonic frequency vibrations to drive autofocus with unrivalled speed and near-silent operation. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot.
f/4 Throughout the Zoom Range - The EF 70-200mm f/4L USM offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 200mm without having to decrease shutter speed. (less)
(Solid Mint-/Clean Glass)
Usable on all Canon EOS series film and digital SLR cameras
Glass is very clean and free of scratches.
Standard Telephoto zoom lens for Olympus 4/3 system Digital SLR cameras. This is NOT a Micro 4/3 Lens.
Fast Wide Angle Zoom Lens. Compatible With Both Film And Digital SLR Cameras.
TSC, which is incorporated into the lens barrel and is often compared to polycarbonate, has a high degree of elasticity and exhibits little variation in its structure in extreme temperature conditions. This means that internal barrel expansion and contraction due to extreme temperature variations is less prevalent. TSC also contributes to the lens' size reduction. The non-macro 18-250mm F3.5-6.3 without TSC weighs 22.2 ounces and is 3.1 by 4 inches in diameter, whereas the new macro lens is 16.6 ounces and 2.9 by 3.5 inches in diameter.
Sigma optimized this lens' power arrangement by incorporating double-sided aspherical lenses and reexamining the design to achieve a more compact filter diameter. The lens has an approximate 13x high zoom ratio with a filter size of 62mm in diameter. Sigma's unique OS system, as well as one Special Low Dispersion (SLD) glass and three aspherical lens glasses, compensate for camera shake and enable correction of color aberration, respectively.
The new 18-250mm F3.5-6.3 DC Macro OS HSM lens is also equipped with Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic Motor (HSM) to ensure fast and quiet auto-focusing, and a rounded, seven-blade diaphragm to create an attractive round blur to the out of focus areas. The lens features a brass-made bayonet mount applied on the surface to reinforce strength for long-term use and enable high accuracy and solidity. (less)
The ZEISS Batis autofocus lenses were developed especially for mirrorless full-frame system cameras by Sony. The lenses are fully compatible with all E-mount cameras and offer protection against dust and splashing water in addition to fast and easy autofocus. For creative work, the distance and depth of field can be read from the innovative OLED display. With the completely new lens design, the high-speed ZEISS Batis family offers perfect imaging performance. (less)
This lens is for use exclusively on Nikon digital SLR cameras with APS-C sensors - not for film SLRs.
Whether shooting movies or stills, image quality is phenomenal, with one UD and one PMo aspheric lens providing high resolution and high contrast images with reduced chromatic aberration throughout the zoom range. A 7 blade, circular aperture ensures beautiful, soft backgrounds and optimized lens coatings ensure excellent color with minimized ghosting and flare. A zoom ring lock even prevents the lens from accidently extending. (less)
