We’ve tested the Pentax K-3 with over 30 different lens models, ranging in focal length from 8mm (equivalent to 12mm in 35mm format) with the 8-16mm f4.5-5.6 DC HSM model from Sigma up to 300mm (450mm equivalent) with the Pentax smc DA* 300mm F4 ED (IF) SDM lens.
We’ve also assessed several of the DA and DA* models, including the new smc DA 18-270mm f3.5-6.3 ED SDM, as well as three of the five new Pentax HD Limited series. We’ve also evaluated the new Sigma 35mm f/1.4 DG HSM Art-series model and the older but modestly priced ($499) Tamron SP AF 28-75mm f/2.8 XR (42-113mm equivalent) model.
Please note while we’ve yet to appraise the FA Limited models - Pentax 31mm f/1.8, 43mm f/1.9, 77mm f/1.8 models or the DA* 50-135mm f2.8 and 60-250mm f/4.0 ED (IF) SDM zooms. However, we will be covering these important models in the future and will update the database for additional comparisons.
