Frank Wong published a review of Tamron’s latest lens, the Tamron SP 150-600mm f/5-6.3 Di VC USD superzoom (Adorama | B&H Photo). Moreover, Frank was so kind to provide an English version of his review (thanks!). More about the Tamron 150-600mm, auto-focus test video, and product and sample pics after the break.
Frank found the lens to be a good performer, with some vignetting between f/6.3 and f/8. Contrast and sharpness also improve stopping down to f/8. Focus speed is good (see videos below). Overall Frank found that the Tamron can not match up with Canon’s EF 500mm f/4 IS (price & specs) and EF 600mm f/4 IS (price & specs), at least not for focus speed and optical performance (but then the Tamron has a pretty lower price tag, $1069, not to mention the flexibility and reach of the zoom range). This appears to be an excellent lens for sport and wildlife photographers. A Canon EOS 5D Mark III was used for the test.
I really encourage you to have a look at Frank’s review, which comes with lots of product pics and sample pics (original size can be downloaded).
