Not only that, I bet some or most FF Pentax lenses already have enough margin on their image cirles to accomodate sufficient SR displacements just like the APS lenses have enough for the APS sensors.
And even if they didnt and SR was not possible across the full frame, you still could do SR across part of the frame, the APS part, if needed. I dont see why FF would totally preclude any SR under any circumstances. I would rather have a FF camers that still can do APS SR if they had to, than an APS w SR camera that cant do FF at all. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Sullivan Sent: Thursday, December 21, 2006 10:59 AM To: Pentax-Discuss Mail List Subject: Re: Official Full Frame Pentax Rumor - Technical Limitations of K Tom, Similar to my thinking in another thread. I think Max Excursion in SR is 2-3 pixels on a 3000+ pixel sensor. No big deal... Regards, Bob S.
