People asked for translation. Here it is as a service,
.
However, I do not translate everything. In fact, I will remove
some non-essential blah-blah-blah.
Evaluation (after the first set of building photos):
Nikon's 8X lens beats eveyone in this comparison. The next one is
Minolta's 7X; however, its 28mm wide angle covers a wider area than
others' 35mm. S602 and 707 perform well. The image quality of
both seems sharp with optical and digital zoom. However, due to
the fact that 707 is an earlier product, it zooming capability is
the last and the metering system tends to underexpose. The zooming
capability of 5700 is very good; however, since there is no IS (or
VR -- in Nikon's terminology) assistance, only BBS can be use to
select the best results.
Evaluation: Exposure Bracket
Evaluation: Close-Up
According to its spec, the minimum working distance is 3cm for the
5700,
and color and focuing are good (NOTE: I don't know the meaning and
the intention of original writing). FinePix can even reach 1cm,
which is the best of the four. However, S602 tends to overexposure
when lacking fill light (NOTE: I don't understand this). F707
frunctuates greatly. We cannot obtain the desired results in a
cloudy day even though F707 may also reach 2cm. A series of shots
shows underexposure and incorrect tonality, which is a big
surprise. Minolta's D7i, judged by its spec (25cm), is the
weakest. However, our testing shows that it is better than that of
the F707, which is also a big surprise.
Evaluation: Continuous Shooting Mode
We look at two factors: burst rate and buffer size. In terms of
burst rate, S602's 5fps is the best, followed by 5700's and F707's
3fps, and Minolta's 2fps. On the other hand, 7i permits to take 6
shots before the buffer is full. This is followed by S602 (5
shots) and 5700 and F707 (3 shots).
I will omit the next three paragraphs.

CK's comments:
The digital zoom testing does not make sense because the four
cameras are not on the same ground. How can you compare a 4X
digital zoom against a 1.4x digital zoom?
We do not know the aperture, shutter speed and ISO settings (and
even white balance) when these images were taken. Were they taken
with exactly the SAME setting? If the answer is no, sharpness
comparison becomes meaningless because of the impact of aperture on
depth of field. It the answer is yes, then the meter systems of
these cameras must have some serious caliberation system, because
the exposure difference is significant. It appears to me that the
images on the second column taken with 5700 and D7i are a little
overexposed. In fact, I suspect that the images on the first
column were not exposed properly. Similar argument can be
applied to the bracket test shots. However, it seems 5700 and D7i
perform better than the other two. Note that I know the
environment and its tonality well.
In summary, the author did some useful work. However, I would like
to see a more rigorous testing.
