in which way is the P45 less integrated with a M645...other then the seperate batteries?
In no particular order:
1) Viewfinder matched to sensor size to provide higher viewing magnification and eliminate mask overlay.
2) Body optical system (mirror and groundglass) and sensor image plane individually calibrated and matched to provide more precise focus. (Refer to Nick-T's excellent post earleir in this thread for detailed explanation) (Refer to link [a href=\"http://www.phaseone.com/KBFiles/1674/1/Focuscheckprocedure.pdf]Phase/Body Focus Check Procedure[/url])
3) Automatic compensation in focusing system for lens focus shift (caused by spherical aberration and corrected based on focal length, distance & aperture) to improve focus accuracy (Again refer to Nick-T's post)
4) Control of back menus and settings from camera grip controls.
5) Option to display histogram on camera grip's LCD to allow viewing of image and histogram without obscuring preview image.
6) Capture data transferred from lens (focal length, distance, aperture) to body to image file for automatic correction of chromatic aberration, distortion and vignetting.
7) Control of manual and auto focus from software (not available yet, but included in new Phocus software)
Control of aperture and shutter speed from software (active feature for years)
9) Automatic Control of shutter, aperture and mirror operation in live video mode. Activate live video and shutter locks open, aperture opens fully and mirror locks up. Aperure can be closed down from software for depth of field preview. Close live video and aperture, shutter and mirror return to previous settings.
10) Dedictated ISO/WB button on camera grip.
11) And from the Steve Hendrix report on the H3D-II...
"GPS capability is now enabled with the GPS unit, which plugs into the left side of the camera body. While some may yawn at this feature (thinking aerial photography), there are actually quite a number of different applications for this feature. Scouting is an obvious one. The ability to GPS search for that street with the cool door you used as a background comes to mind, and I imagine users will find new uses for this feature. From the new Phocus software, Google Earth automatically launches from the software and the location can be mapped and all files shot with those coordinates can be brought up with a simple command. Very cool. The GPS unit is compatible with H3DII and backward compatible with the H3D, H2D and any Hasselblad CF or CFH on H2 camera. Pricing is not yet set but should be announced shortly." I can imagine there could be interest in this feature for landscape and architectural applications as well.
12) Automatic update of the body firmware (which has added a variety of features and improvements) via connection to the back and new software versions.
If I've overlooked something, others can fill in the gaps.
