...............In the 70-200 mm f/2.8 class you pay your money and you take your choice. If you don’t want to compromise and you can afford it, you should consider buying an L lens or a Nikkor 70-200 mm VR. If you can’t pay that much, you also can chose something for yourself. If the optics quality is more important to you than the mechanics quality, the Tamron will be the optimal option. If you decide otherwise, you should buy the Sigma. We could end this test with this judgement of Solomon.
There’s one thing, though, worth stressing. The Tamron 70-200 mm f/2.8 test proved once again how the optics and the antirelection coatings technology has moved forward recently. The constructions, launched nowadays on the market, can compete effectively and show the place in the row to older and more expensive competitors..........
