I look over the reviews on the Tamron SP 70-300 again. Frankly, I am not impressed by the IQ in the 200-300 range. For example, on the Lenstip site, at 300mm the Tamron does not look better than the Nikkor. If Tamron and Nikkor are similar and I have to choose one from the two 70-300s, I would prefer the Nikkor over the Tamron: When fully extended the tamron is longer and, when the lens hood is reversely mounted, the focus ring cannot be touched (I heard that).



The new Sigma 150 macro looks charming, but it is weighty (from a another site I read that it weighs 1400g instead of 1200g; either is not light), and pricy.
