Tamron SP 70-300mm f/4-5.6 Di VC USD

The Tamron SP 70-300mm f/4-5.6 Di VC UuSD is a real beast and weighs in at a hefty 765g.

Designed for full-frame and APS-C sized sensors, the Tamron SP 70-300mm f/4-5.6 Di VC USD is available in Canon, Nikon and Sony mounts and is Tamron’s first lens to employ its Ultrasonic Silent Drive (USD) AF motor.
The lens feels really solid thanks to its muscular build, and on our Nikon-fit example the zoom and focus rings offered masses of grip combined with smooth, fluid movements. There’s no zoom lock but there’s enough resistance to prevent zoom creep when it’s carried vertically. Tamron’s Vibration Compensation (VC) system is featured, and this lets you shoot up to four stops slower if required.
The new AF technology worked well – the motor could barely be heard in use and AF performance was up to speed, too. The lens hastily locked onto subjects at all focal lengths and showed few signs of hunting even in low-contrast conditions. There’s a Broad-band Anti-Reflection multi coating that’s designed to reduce reflections within the lens and the optical design features 17 elements in 12 groups. An Extra Low Dispersion element makes up the lens’s design, and filter users will be glad to hear it uses an internal focusing system. The thread itself is 62mm, and there’s a minimum focus distance of 150cm.
