LensTurbo II samples

A few shots to give some idea what to expect from the new LensTurbo II and A6000 combination. These pictures were taken with the Pentax 28-105mm/3.2-4.5 lens, which becomes approx. 20-76mm/2.3-3.3 with focal reducer. Pictures are unprocessed OOC jpegs.

The LT II is better than the first version, the curvature is less pronounced, less corner CA, and no blue spot. Still, at 28mm the curvature is high for landscape photos, rendering 1/4 of the frame on each side quite soft. At 105mm end the edges are acceptable. The center sharpness and overall contrast are very good.

f = 28mm

f = 105mm

f = 105mm

f = 28mm

P.S. just noticed that the pictures are decompressed and then compressed with higher ratio by the forum software, resulting in significant loss of sharpness
