From the looks of it there aren't many Pentax users on the forum but I thought there may be one or two hiding away somewhere that would be in terested in the new Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW lens. I got mine late last week and managed to get a bit of sunshine on Saturday to give it a quick try.
Here are a few shots, first 4 are just the lens and the others are with the Pentax 1.4x. All handheld with a K-5IIs
