JCO, You need to read what people write. I wrote that the REAL sensor dimensions are absolutely identical when they are uncropped.
"...and the two cameras have equivalent sensor dimensions", were my exact words. They always will be and I never claimed anything different It's the pixel density that's different. All that John Wittingham proposed was to use a K20d and crop away the outer 4 Mpixels to ~effectively~ get a camera with equivalent resolution to a K10d but with a higher crop factor. At least that was my understanding of his musings. He'd be using his K20d as a 4/3 camera with a K-mount. It'd work but I would cost some image quality and give the DOF attributes of the smaller format (provided he cropped every time and never reverted to the entire frame). That said, I have a 4/3 camera and when I get a PK to 4/3 adapter I'll let you know how my M and A lenses perform ;-) Regards, Anthony Farr > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of J. > C.
