On the Pentax K-5, the zooms have near identical rankings with the K-5 IIs, though, naturally, with lower sharpness. The three best performing models retain their position, but the Sigma 17-50mm f2.8 EX DC HSM and the smc DA* 16-50mm f2.8 ED AL (IF) SDM show greater promise on the K-5 IIs than most others with regard to sharpness.
