Hi all, I just encountered a very brief review of the effectiveness of the K100D (Beta) SR. Reviewer is a well known camera writer who always has a privilege for sneak previews.
He is reviewing a K100D + DA 21mm F3.2 AL Limited, but no review of the lens, only on the SR. He talks about the difference between the RS used for A10 (using micro-stepping motors) and the magnetic floating used for K100D which most PDMLers know by now. According to him (who interviewed Pentax engineers), Pentax have been developing this system over so many years, way before Minolta announced the CCD shift method, and even during the film camera era. His point is that the effectiveness of Pentax's SR is more than 2 stops which Pentax so far disclosed. But he found that this was an overly conservative estimate. He experimented it using various lenses and was convinced that it really has more than 3 stops effectiveness. He went on to say, as most of us here know again, that he has to wonder why Pentax have always been very "timid" (his word) in showing this sort of specs. He said he was so frustrated that Pentax do'nt usually brag about their accomplishments. Well, sounds like the Pentax's SR is indeed very effective. Just FYI.
