In our normal outdoor shooting the F700's automatic white balance worked well so I was slightly surprised to see a cool cast (blue-ish) on our outdoor test shot (approx. 5800 K color temperature). In both incandescent and fluorescent light auto white balance led to a pink cast. Otherwise obviously the best possible white balance was achieved with manual preset.

The F700's internal flash has a quoted range of 5 m (16.4 ft) with the camera set to Auto ISO. In our tests the camera produced good white balance if slightly underexposed flash shots. Luckily Fujifilm do provide flash exposure compensation on the F700 so it would be relatively trivial to adjust for an under-powered shot.

The F700 has a fairly limited range of slow shutter speed available for night exposures, in night scene mode the camera automatically engages ISO 400 and allows a slowest shutter speed of 1.5 seconds. In manual exposure mode you can select a slowest shutter speed of 3 seconds. The samples below show that the F700 doesn't perform badly at all but produces cleaner more detailed images at ISO 200.

Barrel and Pincushion Distortion
The F700 exhibited just under 1% barrel distortion at wide angle and no measurable pincushion distortion at telephoto. This is a good performance for a compact extending digital camera lens.
|Barrel Distortion, 0.9% @ wide angle||Pincushion Distortion, 0% @ telephoto|
Vignetting / Lens Shading
Our vignetting / lens shading test is very simple, a shot
of a blank wall from two meters away, vignetting will always be most visible
at wide angle and maximum aperture and will start to disappear at smaller
apertures and/or further zoom. The F700 exhibited no visible vignetting
/ shading at either wide angle or telephoto. Kudos.

Purple Fringing (Chromatic Aberrations)
The F700 did exhibit some chromatic aberrations on our standard test chart (although not too extreme), these only crept into one or two of our everyday shots as a very faint purple halo beside highlight detail.

Overall Image Quality / Specific Issues
Firstly metering, tonal balance and color were all very good, as I have mentioned earlier I am still not overly impressed with the supposed extended dynamic range, most images still have that very distinctive digital camera clipped appearance. One thing that I feel damages the F700's images is the strong and rather unsophisticated sharpening applied, especially at smaller image sizes.
6mp vs. 3mp
We know that the F700's sensor has three million pixel locations (the two photodiodes at each pixel location will make no difference to resolution as they are both under the same color filter and microlens). Fujifilm appear to have further developed their interpolation algorithms, the F700 is the first consumer level SuperCCD digital camera which appears to be able to extract more resolution in its six megapixel image size than at three. Therefore my advice would be to shoot in the 6mp size most of the time.
