Did anyone have a look at the EXIFs that I posted in Dropbox ? By comparing Steeve EXIF and mine, many interesting properties can be seen there :
- new features such as:
- Orientation: Horizontal (normal)
- Roll Angle: -8 (is it degree units? To be checked)
- Pitch Angle: -25
- useful data such as:
- Sensor Size: 7.576 x 5.682 mm (This is bigger than 7.44 x 5.58 mm indicated in DPreview specifications but perhaps in includes additional dimentions for SR. Pentax Q7: Digital Photography Review)
- DSP Firmware Version: 1.01.21.08 (check the sub-sub numbers :-))
- Camera Temperature: 27 C (useful to derive the noise, lower is better, but I did not check accuracy yet)
- Scale Factor To 35 mm Equivalent: 4.6
- Circle Of Confusion: 0.007 mm
- Field Of View: 4.5 deg
- Light Value: 10.7 (this appears only in Steve picture made with 02, does not appear in mine made with a manual focus 100mm macro lens)
- unclear data such as:
- SR Half Press Time: 4.25 s or longer
- Image Size: 4064x3000 (what are those 64 more colums ? Cannot be for SR as there are no additional lines)
