Tamron SP 70-300mm f/4.0-5.6 Di VC USD Lens Review
Review posted 12/7/2010
|Tamron seems to have created a worthy competitor in the 70-300mm zoom
category, with excellent build quality, good optics, and several other
handy features to help you capture better handheld photos; like the USM
AF motor and VC stabilization. Read more in our full conclusion.|
The A005 is a well made lens that Tamron claims is comprised of high-grade materials that allow the unit to offer "best-in-class" resolution. That is a bold statement, which we hope to shed some light on in our review. Albeit, the A0005 does boast some appealing specifications, including the use of extra low dispersion (XLD) and low dispersion (LD) lenses, being their first model to incorporate a fast and quite ultrasonic AF motor (USD), vibration compensation (VC) system with up to a 4 stop gain, full-time MF, and their BBAR anti-reflective coating to combat both lens flare and ghosting.
For those who use a full-frame dSLR, the A005 will cover a nice medium telephoto range of 70-300mm. On an APS-C or "crop body" dSLR, this lens offers a much broader telephoto reach of approx. 109-465mm (in 35mm equivalence). Either range will appeal to a wide range of photogs, whether you're a nature or sports shooter, or anyone else who's looking for an affordable, yet powerful zoom lens option.
The A005 is currently available for Nikon and Canon lens mount systems with a suggested retail price of only $449.99 US.
