Sigma has plastic construction, metal mount. In the Foto Magazin (GER) tests Tamron gets 8.2/8.6 and the Sigma gets 8.4/8.4 - they are close. All the best! Raimo Personal photography homepage at http://www.uusikaupunki.fi/~raikorho

It is a great lens. Great bokeh. Too bad Pentax didn't make it. No flare problems, decent for manual focusing also. I like the stand off distance I get with this lens. Highly recommended. Sorry, no experience with the Sigma(plastic lens mount?). Robert
