You guys know a lot more about these things than I do, but I can't help but thinking that since the *istD is softer than other 6 Mpx cameras, and even softer than other cameras using the same chip, there must be some differences around. Do we know fer sure that there's _one_ optimal degree of softening for a given CCD, and that all the camera makers adhere? Or could it be that Pentax simply put on a slightly too soft filter?
My gut feeling is that trading data loss in downsampling for data loss with a softening filter is tit for tat. I'd love to replace that gut feeling with some real info, though... - In the absence of information, _anything_ is possible...:-) Cheers, Jostein From: "Herb Chong" <[EMAIL PROTECTED]> > in the absence of other information, it's not possible. > From: "Rob Studdert" <[EMAIL PROTECTED]> > > Their understanding of sampling and aliasing differs from mine.
