Review on Pentax 16-45mm f/4.0 SMC PDA ED AL Zoom Lens: Compatible with Pentax and Samsung Digital SLR Cameras by Omar Allen

I LOVE this lens. This is the FIRST DA lens and the design is annoying because it flares out at the short end of the zoom. ODD, but this lens has an amazing sharpness of over 4.5. It also works on ALL PENTAX DSLRs. This is a great glass at an affordable price. Buyer Warning: Be sure to purchase a lens hood with your lens. Lens hoods for these lenses can cost as much as $60. I bought my lens used and there was no mention of a lens hood in the description or photos, so I bought a used lens for $40. To my surprise the bezel came with the lens and I'm sending my second one back.
