Pentax HD DA 35mm f2.8 Macro Limited lens review: Discerning choiceBy Kevin Carter - Friday December 20 2013 Lens Review
Mounted on the mid-range weather-sealed 16-Mpix Pentax K-50, the new HD 35mm f2.8 Macro Limited achieved a DxOMark lens score of 19 points, a somewhat middling score for a lens like this. Part of the reason for this is the low-ish peak sharpness score of 10P-Mpix, which could be attributable to the lens, sensor or both.
Sharpness levels are higher in center with peak sharpness at f4-5.6, but corner sharpness is noticeably lower throughout the aperture range. That’s a little disappointing in a macro where sharpness across the field from corner-to-corner is expected.
Nevertheless, distortion, vignetting and chromatic aberration, a particularly troublesome occurrence in a macro, are all well controlled.
