Tamron A005E SP AF 70-300 F/4-5.6 Di VC USD Lens for Canon

Product Information

For one 1/3 the price of the Canon 70-200 IS (L) the Tamron is surely a great buy and very highly recommended.

I have had quite some lenses. With my canon 550d and 5d mark III i had the 50mm prime, the 70-300 IS, the 70-300 IS L, the 70-200 4.0 L and the 70-200 2.8 II (twice). Now i switched to Nikon and i have the 35mm prime and the 18-105 kit lens. March 9, 2010, Saitama, Japan– President and CEO Morio Ono of optical equipment manufacturer Tamron Co., Ltd., announced another advance in their pursuit of high resolution images in the telephoto lens category with the development of a 70-300mm F/4-5.6 telephoto zoom lens featuring image stabilization––VC (Vibration Compensation) and an ultrasonic auto-focus drive –– USD (Ultrasonic Silent Drive). The SP 70-300mm F4-5.6 Di VC USD (Model A005) high-resolution DSLR telephoto zoom lens has been produced for the Nikon mount, with the development of compatible mounts for Canon and Sony to follow *3. It doesn't seem fair to match the new Tamron against Canon's latest L-glass, so we'll match it against this perennial favorite. This is a lens where Canon got it right - it meets and exceeds the sharpness performance of the Tamron, shows less CA, and less corner shading as well. Distortion is a bit more noticeable on the Canon; both lenses feature USM style focusing and image stabilization. The Tamron has modestly less flare, less barrel distortion at 70mm and modestly less pincushion distortion at 300mm.A gyors autófókusz nem elég: fontos, hogy a bemozdulásos elmosódást is elkerüljük. A VC objektívek kiállták a próbát: elmosódás nélküli, éles képeket készítenek, igencsak rossz fényviszonyok között is. USD Tamron's VC mechanism employs a three-coil system, whereby the three driving coils activate the shake-compensating VC lens groups electromagnetically via three steel balls.

My preference is for a front-positioned focus ring, but there is adequate room for handling is provided behind the Tamron 70-300mm f/4-5.6 Di VC USD Lens focus ring.Because the Tamron SP 70-300 mm is designed for use on cameras with a full frame sensor, when using it on a camera with an APS-C sensor, you won’t be troubled by vignetting. If you ever do encounter it, it must be a picture of a bird against a smooth blue sky made at maximum aperture and the longest focal length. Vignetting is simple to correct later with software if needed. Distortion Ogni modello di obiettivi fotografici riporta delle sigle che ne indicano particolari caratteristiche o funzioni.

This lens’ advanced optical design employs a sophisticated XLD (Extra Low Dispersion) lens element made from specialized high-grade glass that has lower dispersive properties than standard LD lenses (where refraction causes the dispersion of white light into spectral hues). The dispersive properties of the XLD lens are at a level similar to fluorite, and in combination with a LD element make for an optimal optical design that delivers best in class resolution with advanced axial chromatic and magnification aberration correction - major inhibitors of image quality enhancement. The result is a lens that delivers sharp contrast and better descriptive performance throughout the entire zoom range. The difference in image quality between the 70-300 L and the Tamron 70-300 VC is readily apparent in the results. USD is Tamron's latest autofocus motor technology, converting ultrasonic waves into torque to quietly deliver a new level of focusing precision and speed. Because it's still built on a rotor its full time manual focus is as easy as ever; allowing the photographer smooth manual focusing without having to fumble with a switch. With superior optical performance, Tamron’s own USD (Ultrasonic Silent Drive) and VC (Vibration Compensation), the SP 70-300mm Di VC USD (Model A005) provides the performance of a high-end premium telephoto zoom that is appealing to a broad spectrum of photography enthusiasts. As you would expect, this huge improvement in image quality, along with better build quality and much better autofocus performance, comes at a price.Oltre alle sigle che vedi nel nome, è importante conoscere almeno le seguenti ulteriori caratteristiche: Lens Description: In the pursuit to achieve the most outstanding image resolution in the 70-300mm class, Tamron’s Anniversary lens - the SP AF70-300mm F4-5.6 Di VC USD - utilizes an advanced optical design that features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialized materials that prevent chromatic aberration. As a result, the SP AF70-300mm F4-5.6 Di VC USD (Model A005) boasts sharper contrast and greater descriptive performance than all others in its class. In addition, it is the first Tamron lens sporting a USD (Ultra Silent Drive), Tamron’s very own auto-focus drive mechanism This USD mechanism delivers fast, making it a perfect telephoto zoom choice for photographing sports, racing, or other fast-moving subjects. The lens also boasts Tamron’s proprietary VC (Vibration Compensation) image stabilization to assist in handheld photography, not only at long focal length ranges where blurring is common, but also under low-lit conditions, dramatically enhancing photographic freedom. This combination of best in class image resolution, Ultra Silent Drive and Vibration Compensation is a new achievement of Tamron technology culminating in the production of a premium 70-300mm lens. Besides allowing sharp handheld shots to be captured at shutter speeds longer than needed without stabilization, image stabilization makes perfect framing much easier.

It should be noted that our test sample of the Canon 70-300mm ƒ/4-5.6L is actually on par with the Tamron in terms of performance.) The Tamron 70-300mm f/4-5.6 Di VC USD Lens focuses internally and has FTM - manual focus is always available and the focus ring does not turn during autofocus. A Sunsniper Pro Strap so that I can wear the D7000/Tamron at my side while hiking or shooting at outdoor festivals. Come ho scritto sopra... potete mettergli soprannome "Dyson" o "Folletto", è indifferente, ingloba sempre più polvere di quanto immaginate, in compenso (non so come fa) anche se non è tropicalizzato, ha resistito ad ogni foto ai concerti o ad eventi dove pioveva di brutto.Advanced features include ring-type ultrasonic autofocus. Like the similar system fitted in the Nikon Nikkor AF-S VR 70-300mm f/4.5-5.6G IF-ED, it's fast, ultra-quiet and comes complete with full-time manual override in single or 'one-shot' autofocus mode. At 300mm the Tamron is sharper in the corners of the image than the Canon, especially when shooting with a full frame sensor, though there is still a difference in the corners of the APS-C frame.
