Bryan over at The-Digital-Picture has completed his review of the Tamron 150-600mm f/5-6.3 Di VC USD supertelephoto zoom lens. I do not recall another lens by Tamron receiving so many reviews and so quickly. Like the previous reviews, this one gives the Tamron a very good score, but also outlines a few of its weaknesses.
As we've mentioned before, the price will make this lens extremely attractive to a lot of photographers out there.
“This highly anticipated lens has been a very fun lens to evaluate. While autofocus performance and over-500mm image quality get my vote for this lens' weaknesses, the Tamron 150-600 still has a great deal going for it. The Tamron 150-600mm f/5-6.3 Di VC USD Lens is defined by attractive image quality over a great focal length range with a relatively compact, light, reasonably well-built design that includes Vibration Control and a very attractive price.”
