The most expensive of the Pentax lenses in this category 16-50mm did not always deliver everything that it promised. In particular, the f/2.8 aperture is more for bright viewing than it is for top-quality imaging.

    Nice balance and robust feel

  • -

    Slightly stiff and jerky zoom action

This pro-caliber, standard-range, bright digital zoom ($1030, street) is the second Pentax to use sonic-wave autofocusing for very smooth and quiet AF. It works with newer Pentax bodies that accept the KAF2 mount. On older bodies such as the K100, it defers to the noisier, body-housed AF motor.

Purchased this a year ago as upgrade to DA 16-45. Former seems better built. Two issues: when shooting a series of shots at same subject from same position, some will have purple fringing around the edges and others will not. Why? Secondly, the barrel seems very loose when extended.

I've waited a long time to get this lens and that wait was due to the worries of the SDM issues. However, it was assignments at my job that now prompts me to buy. Rather than getting new, I decided to try my luck at used.

This lens is amazing. I was out in the rainforest and got some great pictures in spite of the low light. Fantastic

I have had this lens for more than a year now and my experience is unfortunately quite mixed. I used it mainly for landscapes, with additonal filtering (Hoya Pro 1 D polarizer and Cokin P system).

  • +

    - Weather sealed, - Sharpness, - Color accuracy

  • -

    - Questionable durability/solidness (definitely in my case), - Poor flare resistance, - High level of chromatic aberration, - Needs the largest (and most expensive) square filters (vignetting is visible even with a wide-angle adapter for Cokin P system), - High price
