Pentax SMC DA-L 21817 50-200mm
With a 50-200mm focal range and built-in stabilization, this lightweight telephoto uses an extra-low dispersion element to reduce color fringing on Pentax DSLRs. Its used-market pricing and quiet autofocus make it a cost-effective choice for telephoto reach without sacrificing the convenience of in-lens shake reduction. Pentax APS-C shooters focused on outdoor portraits and casual wildlife shots will get the most value from this affordable zoom.
