New K-3II Review (and its focusing performance)

@ The PB: http://www.photographyblog.com/reviews/pentax_k3_ii_review/

Whilst PB has been positive about the AF performance of the K-3II, our respectful PF, on the other hand, has found something opposite, see:

http://www.pentaxforums.com/reviews/hd-pentax-d-fa-150-450mm-prelim/focusing.html

Quoted, "Although on paper, the Pentax K-3 II promises to bring undisclosed improvements to AF-C performance, we did not observe any evidence of faster focusing, lower latency, or quicker target re-acquisition with the K-3 II."

So, whom should we believe after all? ;-p

Green Ringed GR? :-o

Shootout Again! 645D Vs A7R

I think I have been for long not posting shootout test and here it is, for my old cameras! ;-)

Measurbate and discover by yourself, for all the differences! Original photos are available for viewing by clicking the "Download" option per photo under album! :-D

EXIF data is available for all photos. Pairs of test shoots were taken at almost the same time for the same scene.

Lens used for A7R is a Canon EF35mm F2 (AE and AF adapted) and a FA645 45mm F2.8 for the 645D, for almost identical FoV.

HD 16-85 Measurbation Reviews

Both are done by measurbators, but one with real-world scenes as the shooting targets and the other with test charts in a "lab":

(Tested with K-3, in Traditional Chinese)

(Tested with K-5 II)

The lens model seems to be fairly good. However, it arrives just too late, Canon and Sony had similar models many years ago, when APS-C DSLRs still shined. Nonetheless, I myself feel that the DA17-70 F4 would still be a better lens optically, because of its constant aperture but only a slightly shorter reach. For size and weight wise, the HD 16-85 is not a compact lens anyway.
