JPEG/TIFF Image Size & Quality

Standard Test Scene

The F707 has two JPEG compression levels which can be combined with a variety of image resolutions and JPEG FINE, JPEG STANDARD or TIFF image quality.

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:

  • 2560 x 1920 TIFF
  • 2560 x 1920 FINE JPEG
  • 2560 x 1920 STANDARD JPEG
  • 2048 x 1536 FINE JPEG
  • 1280 x 960 FINE JPEG
  • 640 x 480 FINE JPEG

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

Interesting to note that the TIFF image appears to be very slightly softer, or 'less processed'. Other than that there's little reason to use TIFF (unless you like the idea of using 14 MB a shot), JPEG Fine provides all the detail with little in the way of artifacts (JPEG at least - sharpening halos are clearly visible). JPEG Standard seemed to work quite well, very few artifacts and a good saving in storage space.

ISO (Sensitivity) Adjustment

ISO equivalence on a digital camera is the ability to increase the sensitivity of the CCD to allow for faster shutter speeds and/or better performance in low light. The way this works in a digital camera is by "turning up the volume" on the CCD's signal amplifier, nothing is without a price however and doing so also typically amplifies any noise that may be present and often affects colour saturation.

The F707 now features three selectable ISO sensitivities of 100, 200 and 400 as well as Auto mode which varies sensitivity between ISO 100 and 320 automatically depending on available light. Test images shot under both good and low light.

Good Light (9.3 EV) Low Light (2.4 EV)
ISO 100, 1/13 sec, F5.0 ISO 100, 3.0 sec, F2.8
ISO 200, 1/20 sec, F5.0 ISO 200, 1.6 sec, F2.8
ISO 400, 1/40 sec, F5.0 ISO 400, 1.0 sec, F2.8

Noise levels do on the whole seem to be very good, ISO 100 is relatively clean, there's just the hint of some noise there in the shadow, moving on to ISO 200 and 400 gradually increases the noise but never to distracting levels, interestingly the ISO 400 image looks decidedly less sharp than the ISO 100 image, that's probably down to the new 'Clear Color' noise reduction. The low light, long exposures came out very well, if a little soft.

Picture Effects

Interestingly Sony appear to have dropped the black and white picture effect, you now have a choice of three: Negative, Sepia and Solarize.

No picture effect Negative Art picture effect
Sepia picture effect Solarize picture effect

Today I was comparing one of my first digital camera (F707) with my latest compact camera (RX100 M3) ,aside from resolution the quality of images produced by this two gems are so identical (in good light indeed) . So have we really needed to upgrade our Camera every one or two years to take better photos ? (Thank you SONY anyway , Your engineers doing their duty well)


The Sony F707 was my very first camera, which I purchased way back in June of 2002. Although today (3/2015) I own newer DSLR cameras from Nikon (D200 & D7000), I still love using the Sony F707. After all these years, it continues to deliver excellent image quality...and it has significant sentimental value to me. I just recently purchased a second used F707 on eBay to have as a backup-backup camera in the event that my original F707 quits on me. I wish Sony would produce an F727? model (or a limited edition F707)...I would be the first to buy.


The F717 was my first digital camera and loved it!
