Sony DSC-F707 Review
Compared to... (contd.)
Now we'll compare the DSC-F707 to a few other cameras from our test archives. Here we're comparing colour and resolution to the Minolta DiMAGE 7, Sony DSC-S85 and Fujifilm FinePix 6900Z.
Colour Chart Comparison
Colour charts are shot in daylight, Auto White Balance, EV compensation +0.3 (all cameras), measured light ~10 EV. This test is also dependent on the accuracy of the camera's auto white balance, the colour charts are shot in daylight but some camera's white balance is better than others. All cameras are given 20 seconds to "settle" before the shot is taken.

|Sony DSC-S85||Fujifilm FinePix 6900Z|
In the table below we're only measuring colour. The RGB values were measured from a VGA reduced image (to average colours, remove noise and eliminate JPEG artifacts) using the Eyedropper tool in Photoshop with a 5 by 5 Average Sample Size.
Observations of the Sony DSC-F707 colour balance:
- Gone is the green cast we saw on pre-production camera
- White balance is lacking a little red on the gray scale patches (similar to DSC-S85)
- Red, Yellow and Green saturation has been toned down (since pre-produciton) - better
- Cyan patch is more accurate (compared to pre-production) - better
Red Channel Noise
Something we noticed early on with the current crop of digital cameras was a certain amount of noise in the red channel. This was most visible in the light blue of skies or painted walls. Our colour patch test chart turned out to be a good "leveller" and a way to measure the performance of one camera to the next.
The samples below are of 40 x 40 blocks cropped from the colour comparison charts above of the Blue and Cyan patches. Each block is then broken down into it's red green and blue channels and reflected as such directly below.
A pretty good performance, there is some 'texture' in the red channel on the dark blue patch but this wouldn't be particulary noticeable in every day shots.
Shots here are of the PIMA/ISO 12233 standard resolution test chart (more of which are available in our comparison database). This resolution chart allows us to measure the actual performance of the lens and sensor system. It measures the ability of the camera to resolve lines at gradually higher resolutions and enables us to provide a definitive value for comparison purposes. Values on the chart are 1/100th lines per picture height. So a value of 8 equates to 800 lines per picture height.
Studio light, cameras set to auto, all settings factory default. Exposure compensation +0.7 EV for all cameras.

Measurable findings (three measurements taken for each camera):
|Camera||Measurement||Absolute Res.||Extinction Res.|
|Sony DSC-F707||Horiz LPH||1450||1800|
|5o Diagonal LPH||1000||n/a|
|Minolta DiMAGE 7||Horiz LPH||*1300||1450|
|5o Diagonal LPH||900||n/a|
|Sony DSC-S85||Horiz LPH||1200||*1650|
|5o Diagonal LPH||1000||n/a|
|Fujifilm FinePix 6900Z||Horiz LPH||*1150||1400|
|5o Diagonal LPH||900||n/a|
* Moiré becomes visible
Definition of terms:
|LPH||Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)|
|5o Diagonal||Lines set at 5o diagonal|
|Absolute Resolution||Still defined detail (below Nyquist frequency*)|
|Extinction Resolution||Detail beyond camera's definition (becomes a solid gray alias)|
|n/a||Not Available (above the capability of the test chart)|
|n/v||Not Visible (not visible on test results)|
image detail. Beyond the Nyquist frequency aliasing occurs.
This is more like it. Here's what I'd expected from the new 5 megapixel digital cameras, around 1400 lines/picture height in both horizontal and vertical directions. The DSC-F707 really shines and shows how sharp its lens is and how good it is at resolving fine detail. What's additionally impressive is the way that resolution detail carries on well into the 1800's. And it does so without visible moiré. Based on these results the DSC-F707 is now the new king of resolution for consumer level digital cameras (at the time of writing this review).
Fujifilm has announced the XF10, a premium compact camera with a fast 28mm equivalent F2.8 lens and 24MP APS-C sensor. This replacement for the X70 will ship in August for $500.
