Pentax DA* 16-50mm f/2.8 ED AL IF SDM Review

Verdict
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. Similarly, the SDM system is indeed smooth and quiet but the lens was positively sluggish in comparison to other lower priced offerings in this range from Pentax.
