Title: Disappointed with the Sigma
Review: Optically the Sigma 70mm macro was a decent lens for macro, but not a good all purpose lens at all. The build quality really turned me off. I tried the Tamron 90 macro, better build quality, better optices for both macro and general use. Decided on the Nikon 105 micro with vibration reduction. About 300 bucks more but a world apart in build quality and optics. A truly professional lens. In fairness though, I have to say that for the money, the Tamron was OK.
