First K100D review with samples
Translated. Includes interesting interview with one of developers. Ken was right - SR was in development for about 20 years!!! And results are very good, even with shutter speeds 3 stops lower than it would be normally required. http://translate.google.com/translate?langpair=ja~enu=http%3A%2F% 2Fkakaku.com%2Farticle%2Fad%2F06%2Fk100d%2Findex.html Cheers, Sylwek -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

However, one question comes to mind: They describe the SR mechanism as a kind of frictionless electromagnetic system, taking no energy loss. Ok - no energy loss is marketing speech. It will take energy to accelerate the sensor in one direction, it will take energy to stop it again, and it will take energy to move it back. Frictionless sounds like some kind of magnetic levetation. This would mean, that when powered on the CCD will lift of the zero-position for a minimum amount of space. This lifting would shift the projection area. AF needs a different focus adjustment. Does the camera refocus when you turn SR on and off? -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

I suspect you are taking the anal-literal approach to reading these things. William Robb -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

It's the view of a technical person who does try to understand the function behind. Others don't mind there anal results or oral input, as long as there's anything in between.

Re: First K100D review with samples
Thanks for posting the link. Reading google translate japanese is itself worth the effort for the laughs. :-) Sounds like very good AF performance and SR performance. Bodes well for the 10Mpixel body too. Godfrey On Jun 20, 2006, at 1:05 AM, Sylwester Pietrzyk wrote: Translated. Includes interesting interview with one of developers.

Re: First K100D review with samples
I've read with interest what PDMLers say about Pentax antishake, but I remember reading, I think on DPreveiw, about the Optio A10 where antishake results were inconsistent. Mind, many think those folks have a bias against Pentax. I would guess the DLSRs that are a' coming would have better implementations. I'm not gonna consider them until I hear the early adopters here (and thank goodness we have some) post THEIR reports HERE. Meanwhile, film cams and an Optio SV. Heck, I don't need nothing new til something BREAKS. Grin. -Lon Sylwester Pietrzyk wrote: Translated. Includes interesting interview with one of developers.

In A10 sensor is moved using microstepping motors, while in K100D it is moved be electromagnetic field - guess which one is more responsive? ;-) -- Best regards Sylwek -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
