Best lenses for your Pentax K-50: Pentax lens overviewBy Kevin Carter - Thursday August 22 2013 Lens Recommendations
The best performing standard zoom in our database is the $335 Pentax smc PENTAX DA 16-45mm f/4 ED AL with a DxOMark score of 17 points. However, while it was only introduced in 2003, that lens can be difficult to find new, being replaced by the $736 16-50mm f/2.8 and the $599 17-70mm f/4 AL (IF) SDM (not yet reviewed). Although the 16-50mm f/2.8 ED is a good performer on the K-50 the DxOMark score is held back slightly due to high levels of chromatic aberration, but in all other respects it would make a good choice.
