The-Digital-Picture has completed their review of the Tamron 100-400mm f/4.5-6.3 Di VC USD. At just $799, this is a very affordable 100-400mm option.
From The-Digital-Picture:
The Tamron 100-400mm f/4.5-6.3 Di VC USD Lens adds a very interesting choice to the mid-to-long telephoto zoom lens options list. This lens (and its Sigma counterpart) delivers image quality close to that of the major camera brands' own offerings at a substantially lower price point. And, at a substantially lower, more-easily-portable weight.
This lens does not forgo the expected quality features, including vibration compensation, fast USD autofocus and moisture-resistant construction. It looks great and the smooth design feels great in the hand. The focal length range being an extremely useful one brings great value into the equation. Read the full review
