Review on Pentax D FA F2.8ED SDM WR 15-30mm f/2.8: The Ultimate Pentax K Ultra-Wide Angle Zoom Lens by Ken Lawson

I haven't had a chance to really practice with this lens, but I really like what I've seen. Ultra sharp throughout the zoom range, great in low light, fast and quiet focusing and a wide range make this a great addition to my K1 arsenal. It's big, heavy, but I knew that when I ordered it. My only gripe and the reason for only 4 stars is the non-removable hood and inability to install standard thread filters.
