Tamron 150-600mm f5-6.3 Di VC USD Canon mount lens review: New contenderBy Kevin Carter - Wednesday February 12 2014 Lens Review
Tamron has released a new modestly priced, stabilized super-telephoto zoom for both full-frame and APS-C cameras, the SP 150-600mm f5-6.3 Di VC USD. How does this $1,100 model compare against the slightly shorter-range Sigma and Canon offerings?
Aimed at wildlife, bird and action photographers, the newly designed super-telephoto Tamron 150-600mm f5-6.3 Di VC USD zoom looks to be a promising update to the non-stabilized 200-500mm f5-6.3 Di LD [IF] (A08) model it replaces. As well as the longer range and built-in stabilization the new model also features an ultrasonic type AF motor and adds the firm’s new eBAND (Extended Bandwidth & Angular Dependency) coating to their existing BBAR (Broad-Band Anti-Reflection) coatings to reduce flare and ghosting. The new model boasts a complex optical construction consisting of 20 elements in 13 groups including three LD (Low Dispersion) elements to reduce CA as well as a 9 blade circular aperture for softer transitions to out-of-focus areas.
Measuring 10.1 in (257.8mm) and weighing 68.8 oz (1,951g) the new model is just over 1-inch longer but around 60% heavier than its predecessor. The earlier iteration also focused to just 98.4 in (2.5m) whereas this lens has a minimum focus distance of 106.3 in (2.7m) although both are quoted as having a magnification ratio of 1:5. Priced at $1,069, the new lens is available in Canon mount only to begin with, though Nikon and Sony A mount versions will follow.
