In K-5 and K-7, when you select RAW you have only the choice of the RAW file format: DNG or PEF. The RAW file is recorded with the full camera sensor resolutions. In other words, in RAW you canot downgrade the resolution (in camera) and you cannot choose between 1 star, 2 stars, .. or 12 Mp, 10 Mp, 6 Mp.
For a *stD, you can choose between the following file formats:
• RAW (12-bit)
• TIFF (8-bit RGB)
• JPEG (EXIF 2.21) - 3 levels
I read that you turn the front dial to select image quality:
•
(JPEG)
•
(JPEG)
•
(JPEG)
• TIFF
• RAW
and the the rear dial to select image size (where applicable):
• Large
• Middle
• Small
Hope that the advice will assist, mate...
