JPEG/TIFF Image Size & Quality

The F601Z provides eight different image size / quality combinations. There are three image quality settings at 6 megapixels (2832 x 2128), two each at 3 megapixel and 1 megapixel and a single VGA mode. Because of the honeycomb structure of the F60!Z's SuperCCD none of these can truly be considered the cameras 'native resolution', however the 2048 x 1536 size is nearest to the quoted number 3.1 million pixels on the CCD.


Standard Test Scene

To give an impression of what some of the combinations of image size and quality produce the table below is a cross reference of some of them:

  • 6mp: 2832 x 2128 FINE JPEG
  • 6mp: 2832 x 2128 NORMAL JPEG
  • 6mp: 2832 x 2128 BASIC JPEG
  • 3mp: 2048 x 1536 FINE JPEG
  • 1mp: 1280 x 960 FINE JPEG
  • VGA: 640 x 480 NORMAL JPEG

Images below are cropped 240 x 100 area of the image magnified 200% (nearest neighbour).

As you can see the six megapixel output images do look soft and heavily processed, those who are used to SuperCCD won't be overly concerned about this. There appears to be very little to be gained from shooting at the Fine setting at the six megapixel output size, Normal appears to maintain just as much image detail. Down to three megapixels and the images look far more acceptable and sharper.


Image Sharpening

The F601Z provides three different sharpening levels. I personally found the 'Normal' sharpening to be a little too much and the soft setting to be too soft. It would have been nice to have a setting between Normal and Soft or that the Normal setting was slightly less.

Sharpening: Hard
Sharpening: Normal
Sharpening: Soft
