Considered this lens for some time. At the end, ordered the Pentax DA* 300. It should come this week. The Sigma 120-400 is almost 4 lbs. The Pentax is 2.3 lbs. I just did not want that much weight. Second, it seemed to me that 300 mm is about the right length for outdoor animal shots. For some birds, it will fall short, but so will this Sigma. I will not miss 400mm with the Pentax 300, because I have the Tamron 1.4x TC. We are planning to take an Alaska Cruise, and the Pentax weather sealing will be handy there. Unfortunately, the Pentax is quite a bit more money.

I owned one for a week and returned it (posted a review in the third party section -- ( Third-Party Pentax Lens Review Database - Sigma APO 120-400mm F4.5-5.6 DG HSM). I found I get better results with the f*300mm and a teleconverter. I'd recommend the f*fa*/da* 300mm over this lens. Another good choice is the Sigma 100-300mm plus a sigma tc.
