Thanks for the answers so far. I am really curious to see how this works (technically and results-wise). From a marketing standpoint it sure gets Pentax attention for offering something (on top of an already acclaimed camera) that Nikon and Canon don't have and can't replicate since they don't move the sensor.
I'm a bit concerned that it is considered "RAW Development". We know that it is 4 separate digital exposures, but that doesn't appear to mean that you have 4 separate RAW exposures. In fact, I'm wondering what the RAW file looks like. I'm hoping this isn't simply a "high definition" JPEG that is created. Since the development is "in camera" I'm also concerned over how long that development takes before you get control of the camera back again. A third concern is what shutter speeds it can handle. It would work very well with the AstroTrack unit built in for Astrophotography, but only if it works on B (controlled by an external shutter timer) and I'm wondering if it will. (Though if it doesn't that would be POSSIBLE to add in a firmware update (menu setting). AstroTrack is already moving the sensor to compensate for star trails. So it would need to be set up as more of bracketing situation: Sensor is tracking stars... electronic shutter opens (say for 60 seconds)... electronic shutter closes... sensor jogs one pixel and continues tracking... electronic shutter opens (for another 60 seconds) Rinse and Repeat for a total of 4 times. This "bracketing" technology could also work without AstroTrack turned on, which is what astrophotographers would need if they had their own tracking platform or telescope mount with camera attached. In that case, all they need is 4 consecutive "B" exposures with the pixel shifting between the 4 exposures. But what the astrophotographer needs is 4 separate RAW files I fear that this is NOT what pixel-shift means when used in a "RAW development" sense. On Thu, Apr 23, 2015 at 8:06 AM, P.J.
