The optical system, construction, and exterior are the same as the EF 75-300 mm f/4-5.6 III USM’s. The difference is that it uses a DC motor instead of a USM to drive the AF.Format Compatibility: 35mm Film / Full-Frame Digital Sensor,Canon (APS-C).
A unique and indispensable addition to Canon’s series of EF lenses, the new EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance. The EF 40mm f/2.8 STM’s unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance. Its diminutive design is complemented by features such as a newly developed stepping motor for smooth and quiet continuous AF while capturing video with the Canon EOS Rebel T4i DSLR, a circular aperture (7 blades) for beautiful soft-focus backgrounds, and a short minimum focusing distance of only 0.98 ft./0.30 m.1-Year Warranty
New ultra-high ratio zoom lens AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II for use expressly with Nikon DX-format digital-SLR cameras.Dimensions (DxL) Approx. 3.0 x 3.8″ (7.62 x 9.65 cm).A number of unique Nikon technologies have been developed for, and applied to, including a high zoom magnification of 11.1x, a Vibration Reduction (VR II) image stabilization system that provides camera shake compensation equivalent to increases in shutter speed by four stops, and a Silent Wave Motor (SWM), as well as a zoom lock switch. Designed expressly for use with Nikon digital-SLR cameras, exceptional image performance is assured. As the compact AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II covers an extremely wide range of focal lengths (18-200mm, equivalent to 27-300mm in 35mm format; a zoom magnification of 11.1x), it offers excellent versatility for various scenes that include portraits and landscapes. The addition of a zoom lock switch allows photographers to secure the lens barrel at its minimum length, eliminating the natural gravitational effect that can draw the barrel downward during transport. This lens offers superior optical performance in a compact size of just 77 x 96.5 mm, despite a high zoom magnification of 11.1x. Nikon’s Silent Wave Motor (SWM) assures fast and quiet autofocusing. The Vibration Reduction system (VR II) provides camera shake compensation equivalent to increases in shutter speed by four steps.What’s in the box: Nikon AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II Zoom Lens, 72mm Snap-On Lens Cap, LF-1 Rear Lens Cap for F Mount Lenses, HB-35 Lens Hood, CL-1018 Lens Case, 1-Year Nikon Warranty (5-Year Extension is Available After Registration with Nikon).
The Canon EF 24-70mm f/2.8L II USM Lens is a standard focal length zoom lens. It features a large aperture throughout its focal length. Featuring the latest advances in optical lens design, it utilizes 1 Super UD lens element and 2 UD lens elements that help minimize chromatic aberration in the periphery at wide-angle, as well as reduced color blurring around the edges of the subject.
In addition, 2 types of aspherical lenses are combined to help reduce spherical aberration over the entire image area as well as through the full zoom range. Optimized lens coatings also help ensure exceptional color balance while minimizing ghosting. The lens is also equipped with a circular 9-blade diaphragm for beautiful, soft backgrounds. A ring-type USM and high-speed CPU with optimized AF algorithms enable silent and fast autofocusing.
Built for the rigors of professional use as well as to meet the increased number of shots available with digital photography, it’s constructed with improved dust sealing and water resistance while fluorine coatings on the front and rear lens surfaces help reduce soiling, smears and fingerprints. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera.
The ultimate extended-range, ultra-wide-angle zoom lens! Wider and longer than others in its class, this compact, lightweight, high-performance lens for DSLRs with APS-C size sensors provides 35mm equivalent coverage from 16mm ultra-wide to 37mm semiwide, a remarkable 2.4X zoom ratio. With a maximum coverage of over 108°, this state-of-the-art classic is the perfect solution for expanding your visual horizons.

Super Performance (SP) for Discriminating Shooters
Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters—they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.
Internal Focus (IF)
Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.

Low Dispersion (LD)
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
Aspherical Elements (ASL) Provide the Ultimate in Image Quality and Compactness)
Tamron uses several hybrid aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens elemen tcan take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.
