Brand: Tamron Model: AF061N-700 Dimensions: 2.00" h x 2.00" w x 3.50" l, World's smallest and lightest 28-300mm lens (June 2004) 28-300mm focal length f/3.5-6.3 maximum aperture XR (Extra Refractive Index) glass Multipurpose lens for Nikon 35mm film and digital SLRs; macro to telephoto ranges
Reach out and grab distant detail, wildlife, and sports action with this amazing 11X extended range wide-to-super tele zoom that covers both full-frame and consumer DSLR (APS-C) formats allowing you to focus down to an incredible 0.49m(19.3") (1:2.9) for breathtaking close-ups. If there’s any compact zoom that does it all on digital and film SLRs, this is it. Breathtaking close-ups AF28-300mm F/3.5-6.3 XR Di LD Aspherical (IF) Macro Highlights Di II Maintaining the high performance of the previous model, Tamron's 28-300mm zoom lens now features our "Di" design, making it the ideal lens for use with both digital and film cameras. The "Di" design is achieved by applying a new optical design to its coated surfaces, and by further enhancing our already stringent quality control system. Whether you shoot film or digital, the lens provides high image quality for both platforms. When used with APS-C size digital SLR cameras, the lens provides an angle of view equivalent to approximately 44-465mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range. 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.) Low Dispersion (LD) Glass for Greater Lens Sharpness Anomalous Dispersion (AD) for Better Color Correction Anomalous dispersion (AD) glass is a special type of optical glass that is used to achieve more precise control of chromatic aberrations, thereby enhancing overall imaging performance. Glass of this type provides an abnormally large partial dispersion ratio (amount of diffraction) for light of specific wavelength ranges (colors) within the visible spectrum. By combining AD glass having these special characteristics with elements made of normal glass having different dispersion characteristics, it is possible to control the dispersion factors of a specific wavelength. This enhanced level of control results in much lower levels of on-axis (central) chromatic aberration for telephoto lenses (or zooms used at tele-photo settings) and a significant reduction of lateral (peripheral) chromatic aber-ration for wide-angle lenses (or zooms used at wide-angle settings.) Anomalous Dispersion Extra Refractive Index Glass (XR) Extra Refractive Index (XR) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations. This has allowed Tamron to develop a line of shorter, smaller-diameter, lighter lenses without sacrificing lens speed, and actually upgrading image quality compared to older designs. XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making possible many of the outstanding and innovative lens designs that bear the XR designation. XR glass, with its superior light-bending power, makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens—even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry by hand. Special glass for better performance and more compact lens designs 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. Achieve the ultimate in image quality with Asperical (ASL) lenses 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. Zoom Lock (ZL) Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.
Customer Reviews more useful 78 of 80 people found this review helpful. Great quality, terrific value for Gadgester (Tamron also makes this lens available for Canon and Pentax digital SLRs, for the same price.) This new zoom lens Tamron friendly D-SLR is a great way to capture a high-quality zoom for fraction of the cost if you purchased the camera manufacturer (for example, Nikkor). Tamron claims that the world is the "smallest and lightest" zoom zoom. I have no idea if this is true. And 'small and light, in fact, about the same size as the DX lens equipped with Nikon D70, but it feels lighter in hand. For me it is a plastic lens, but the lens made in Japan, looks and feels solid. It has all the bells and whistles of a modern lens: XR, LD, asperical, plus the ability to macro. In the real world shooting, I'm very happy with the result, and I really do not think buying a Nikkor lens officials have made much difference. Two things to keep in mind, 1), provided that you buy especially fire a lens (Tamron, Sigma, Vivitar, and maybe) you get a good deal, and 2) the incremental increase in lens quality (perceived or real) of the camera manufacturer is extremely unlikely that an appreciable amount of images by Ansel Adams a disposable camera to enhance pictures and he's still better than you and me, period. While a high quality lens, if it is able Tamron, you are armed with all the equipment you need in order not to lose a great picture opportunity. The only ingredient that no one can sell is your creativity. (Unfortunately, the last thing I need and try to improve. For now at least the Tamron gives me the right tool.) For the Nikon digital SLRs, the 1.5 "expansion" factor (or crop factor) means that the effective focal length length of the Tamron is about 43,460 in 35mm equivalent. In short, this is really a high quality lens Nikon D70 that every enthusiast should consider. This is a great bang for the buck, and still in Japan, unlike many official Nikon lenses, which found in sweatshops in Southeast Asia, 43 out of 43 customers have made this review helpful. If you buy only one goal, that's it. By Lydia Lee When I got my DSLR, I'm not the "kit" lens. I just wanted to be able to take two shots and macro-zoom, and I had no money to more than one goal of good quality. So I did some research and read reviews online and when I bought my new camera, I had the Tamron 28-300. I have an excellent choice. If you buy a single lens, this lens is. Macro Recording The goal is clear and detailed. For example, in a photo I recently took my Pomeranian every hair that sticks up is visible and clear, strand by strand. The versatility of the lens that I can take pictures of landscapes, pictures of birds in my garden, portraits, almost everything that strikes me. Every time they are sharp and the colors well. I love this goal is still my main goal. 57 out of 60 people found this review helpful Great, when only a slow way by Digital Shutterbug got this lens for my wife with a Nikon D-50 just before a 2 week trip to Africa. First impression was that the lens was very light and compact and has a number of exceedingly rich wideangle zoom capability. On the positive side, this lens on the camera all the time and my wife has got some amazing pictures that I missed while I was fumbling for change lenses. On the negative side, I swapped cameras with her one evening and found the target must be less than fantastic in low light (ie, slow shutter speeds required), even at low zoom settings and even up to ISO 400 on the camera. I have found that shutter speeds so slow that I could not hold the camera without blur from vibration of the lens (1 / 30 or slower) while the other with my Nikon 70-300mm 1:4.5-5.6 was still good pictures. Also, I discovered that the digital camera with its 1.5 Multiplier 5x wide-angle end of the 28 mm lens was not wide enough for some of the great
