Sony DSC-F707 Review
The 2 megapixel DSC-F505 was originally revealed back in August 1999, and we were the first site to review it. In April 2000 Sony announced an upgraded camera named the DSC-F505V, it was essentially the same lens and camera engine but with a 3.3 megapixel sensor. Because the lens system wasn't altered the F505V couldn't cover the required 3.14 megapixels, instead it produced a 2.6 megapixel (1856 x 1392) image.
So here we are some 16 months after the F505V, and some two years since the F505, Sony has revealed the 5 megapixel F707. This digital camera has the same lens / swivelled body design of the F505, indeed at first glance their are a lot of similarities, look closer and you'll see that this camera is an impressive evolution in the best sense of the word.
The F707 still features a 'Carl Zeiss' lens, of course this time focal lengths have had to change, the F707 uses a larger 2/3" CCD compared to the original 1/2" CCD (2 megapixel F505). The old lens had a focal length range of 7.1 - 35.5 mm (5x, 38 - 190 mm equiv.), the new lens has a focal length range of 9.7 - 48.5 mm (5x, 38 - 190 mm equiv.). Also of interest is that the new lens is quite a bit faster than the old, the old lens had maximum aperture of F2.8 at wide angle and F3.3 at telephoto, the new lens has a maximum aperture of F2.0 at wide angle and F2.4 at telephoto (that's a stop faster).
Review update (5th September 2001)
This review was originally based on a pre-production DSC-F707. I have now completed updating this review with results from a full production DSC-F707. As well as fully verifying the review text I have also re-shot a lot of samples and updated test results etc. For those who read the review before this update here's a log of changes:
|Introduction||Review update||Add||Added this item|
|Body/Design||All||Verify||Green dot on nightshot switch|
|Operation||Top controls||Update||Updated text and image|
|Timings & Sizes||Performance||Verify||Faster: power up, shot to shot|
|Features||Night Shot||Re-shoot||Better night shots, almost no 'black holes'|
|Image Quality||Resolution Chart||Re-shoot||Identical result|
|Image Quality||White Balance||Re-shoot||No more green cast on daylight AWB|
|Image Quality||Clipped reds||Verify||Now with comparison to Canon G2, red is better|
|Compared to..||DiMAGE 7||Update||Added 'pre-production' notice, moved to end|

F707 vs. F505V
Here's a quick summary of the primary differences between the DSC-F505V and the DSC-F707.
The DSC-F707 becomes the second digital camera we've reviewed which uses the new 2/3" 5.24 mp Sony ICX282 CCD. The camera outputs a 4.92 megapixel image (2560 x 1920) from this CCD. Coming from the 2.6 megapixel F505V this is certainly a big step up, the diagram below will give you a visual scale display of the difference between 2.6 megapixels and 4.92 megapixels.
Here are a few other ways of thinking about the increase in resolution (compared to the F505V's 2.6 megapixel image):
- The output image is 704 pixels wider and 528 pixels taller
- The output image has 2.33 million more pixels
- Prints at 150 dpi would cover an extra 4.7 inches horizontally and 3.5 inches vertically
