I've begun including links in our reviews to a Thumber-generated
index page for the test shots. The Thumber data includes a host of information
on the images, including shutter speed, ISOsetting, compression setting,
etc. Rather than clutter the page below with *all*that detail, we're posting
the Thumber index so only those interested inthe information need wade through
it!
High contrast demands a slight underexposure, but good color and high
resolution. Slightly higher than average image noise.
The extreme tonal range of this image makes it a tough shot for many
digicams, which is precisely why I set it up this way, and why I shoot
it with no fill flash or reflector to open the shadows. The object is
to hold both highlight and shadow detail without producing a "flat"
picture with muddy colors, and the Coolpix 5200 produced fairly bright
color, but high contrast.
Captured using the 5200's low-contrast option, the
shot at right was taken with a +0.7 EV exposure
compensation adjustment, which did a fairly good job of preserving the
strong highlights, albeit at the cost of rather dark midtones.
I chose the Auto white balance as the most
accurate overall, though it wasn't much different from the Daylight
setting. (The Manual setting resulted in
a pronounced green cast.)
Overall color is a slightly cool, with excess magenta in the skin tones.
The blue flowers are almost rendered quite well though, with about the
right amount of purple in them. (Many digicams have trouble with this
blue, often making it too dark and purplish. The 5200 does better than
most with them.) Color looks good throughout the rest of the frame, with
appropriate saturation. Resolution is interesting: There's a load of fine
detail here, although there's a bit of a softness to the image overall,
and image noise is a bit higher than normal. It looks like Nikon deliberately
went very light on the anti-noise processing, with the result that the
Coolpix 5200 does a very good job of preserving fine detail in areas of
subtle contrast, as in Marti's hair. At the same time, they went easy
on the in-camera sharpening. The net result is a slightly soft-looking
image that nonetheless has a great deal of detail in it, and that takes
sharpening on the computer very well. As noted, image noise is a bit higher
than I'd like to see, but probably about on par with other five-megapixel
cameras these days.
To view the entire exposure series from -0.3 to +1.3 EV, see files CP52OUTAM1.HTM
through CP52OUTAP4.HTM on the thumbnail index page.
Saturation Series: The Coolpix 5200's saturation adjustment works well, providing fairly
subtle variations in color saturation. I'd like to see a greater number
of steps of this same size, but overall, my strong preference is for saturation
controls to be subtle, rather than blatant. (This makes them much more
useful as actual photographic tools, rather than special-effects gadgets.)
The saturation adjustment does seem to have some impact on image contrast
though, an undesirable side effect.
Contrast Series: The Coolpix 5200's contrast adjustment works exactly as it should,
affecting the highlights and shadows of the image about equally, and leaving
the color saturation more or less unaffected. I'd like to see the camera's
overall contrast a little lower, but the contrast adjustment control does
a fairly good job of dealing with the deliberately harsh lighting of this
shot.
High resolution, slightly soft look, but exceptional
fine detail.
Exposure is slightly better in this close-up shot
than in the wider shot above, and the 5200's 3x optical zoom lens helps
prevent any distortion of Marti's features up close like this. Contrast
is again somewhat high, but the exposure is a bit better balanced in this
shot. The shot at right was taken with a +0.3 EV exposure compensation
adjustment, and the highlights are blown out on the white shirt, but Marti's
skin tones are quite good, albeit slightly ruddy. As before, a very conservative
use of in-camera sharpening results in a slightly soft-looking image,
but equally conservative noise-suppression processing results in an image
with exceptional fine detail that comes out very nicely under strong,
small-radius unsharp masking. (Try 250% at an 0.4 pixel radius.) A very
good performance.

through CP52FACP3.HTM on the thumbnail index page.
Great intensity and coverage with the built-in flash, even at the
default exposure.
The 5200's built-in flash illuminated the subject very well at its default
exposure setting, with excellent coverage and intensity. Overall color
is slightly orange from the strong background incandescent lighting, but
results are still pretty good. The camera's Slow-Sync
flash mode produced similar results, and also looked best at the default
exposure.
To view the entire exposure series from zero to +1.0 EV in the normal
flash mode, see files CP52INFP0.HTM through CP52INFP3.HTM on the thumbnail
index page.
To see the same series in the Slow-Sync flash mode, see files CP52INFSP0.HTM
through CP52INFSP3.HTM, also on the thumbnail index
page.
Acceptable color with all three white balance settings (best with
the Manual option though), and a good exposure. Slightly high noise at
the higher ISOs, with a strong grain pattern.
This shot is always a very tough test of a camera's white balance capability,
given the strong, yellowish color cast of the household incandescent bulbs
used for the lighting. The 5200's Manual white
balance did the best job here, with an accurate white value on Marti's
shirt and pleasing overall color. The Incandescent
setting produced pretty good results, but with a warm cast (though some
may prefer the warmer color balance, feeling that it does a better job
of matching the color of the original lighting). The Auto
white balance setting produced a stronger yellow cast, warmer than I'd
like, but still just within what I'd consider "acceptable."
Skin tones are slightly pinkish, but still good, and the blue flowers
are dark and purplish (probably to be expected, given the light source).
The best exposure was obtained with a +1.0 EV exposure compensation adjustment,
which is about average for this shot. ISO Series:
I was surprised by how low the noise levels were on this shot, as the
need for heavy white balance compensation by the camera imposed by the
incandescent lighting usually results in very high noise levels in the
blue channel. At ISO 64, the noise is for all intents and purposes non-existent,
and very low at ISO 100 as well. It increases gradually from there, becoming
fairly strong at ISO 400. Overall, a pretty good performance though.
High resolution with good detail, nearly accurate color with the Auto
white balance.
Though just a hint warm, the 5200's Auto
white balance setting produced the best overall color here. The Manual
setting resulted in a more accurate white value, but the overall color
balance was a bit cool for my taste. (The Daylight
setting resulted in a much warmer color balance, though results were still
good.) Resolution is high, with quite a bit of detail in the tree limbs
above the roof, as well as in the shrubbery and brick pattern. As before,
images straight from the camera are fairly soft, but take sharpening well
on the computer. There's a little additional softness in the corners,
but less than average, except for the upper left corner.
Excellent fine detail, somewhat hidden by conservative sharpening,
higher than average image noise, excellent dynamic range.
This image is shot at infinity to test far-field
lens performance. NOTE that this image cannot be directly compared to
the other "house" shot, which is a poster, shot in the studio.
The rendering of detail in the poster will be very different than in this
shot, and color values (and even the presence or absence of leaves on
the trees!) will vary in this subject as the seasons progress. In general
though, you can evaluate detail in the bricks, shingles and window detail,
and in the tree branches against the sky. Compression artifacts are most
likely to show in the trim along the edge of the roof, in the bricks,
or in the relatively "flat" areas in the windows.
This is my ultimate "resolution shot,"
given the infinite range of detail in a natural scene like this, and the
5200 performs pretty well. The tree limbs over the roof and fine foliage
in front of the house show strong detail, with good definition in the
leaf patterns. The image is again a bit soft overall, but the actual level
of detail is exceptional, as revealed by sharpening in an imaging program,
post-exposure. Overall color and exposure
are very good. The table below shows a quality series at maximum resolution,
followed by ISO and sharpness series. (The sun was very fickle on the
day of this shoot, so I couldn't fit in a full size/quality series.)
Sharpness Series: The Coolpix 5200's in-camera sharpening is very conservative, even
at the "high" setting. I'd recommend most users simply set the
sharpness to High and forget about it, as the resulting images are still
none too sharp, and show virtually no sharpening-related artifacts.
I routinely shoot this series of images to show the field of view for
each camera, with the lens at full wide angle, at maximum telephoto (3x,
in this case), and at full telephoto with the digital zoom enabled. The
5200's lens is equivalent to a 38-114mm zoom on a 35mm camera. That corresponds
to a modest wide angle to a decent telephoto. Following are the results
at each zoom setting.
Pretty good color with the Daylight white balance setting, and high
resolution.
This shot is often a tough test for digicams, as the abundance of blue
in the composition frequently tricks white balance systems into producing
a warm color balance. Both the 5200's Auto
and Manual white balance settings produced
slightly cool color balances, while the Daylight
setting produced more pleasing results (though just a hint magenta). The
blue robe looks about right, with only faint purplish tints in the deep
shadows, and skin tones are good, but reddish. Resolution is high, with
good detail in the embroidery of the blue robe and red vest.
Typically excellent "Nikon" macro performance. Flash is
blocked by the lens, however.
As I've come to expect from Nikon digicams, the Coolpix 5200 performed
very well in the macro category, capturing a minimum area of only 1.21
x 0.91 inches (31 x 23 millimeters). Resolution is high, with a lot of
fine detail in the dollar bill. However, the coins and brooch are soft
due to the very short shooting distance. (An optical fact of life, not
the camera's fault.) As with many digicam ultra-macro modes though, there's
a lot of softness in the corners of the image. The 5200's flash
is partially blocked by the lens, resulting in a dark lower right corner
and an overexposed upper left corner. - Plan on using external illumination
for your closest macro shots with the 5200.
Good color, saturation, and exposure, though contrast is high.
The 5200's Manual white balance setting did
the best job here, as the Auto and Daylight
settings were a bit warm. Exposure is good, though contrast a bit high,
and the camera has no trouble with the subtle tonal variations of the
Q60 target. The large color blocks show good hue accuracy and saturation,
though the additive primary colors (red, green, and blue) are brighter
than the rest. Highlight detail is good, but the darkest shadow areas
are plugged up, and the camera can't distinguish between the two darkest
steps on the large grayscale. A good performance overall though.
The results below are more or less the same as we saw in similar series
with other test subjects, so I won't bother repeating my earlier comments.
(I nonetheless include these images because they provide more analytically-minded
readers the means to study image characteristics with well-known target
objects.)
Slightly limited low-light shooting capabilities, but very usable
for average city street lighting at night. Excellent low-light focusing
capability.
The Coolpix 5200 produced clear, bright, usable images only down to the
one foot-candle (11 lux) light level at the 64 and 100 ISO settings. Performance
improved with the 200 and 400 ISO settings, with bright images as low
as the 1/2 and 1/4 foot-candle light levels (5.5 and 2.7 lux) respectively.
The Night Landscape mode adjusts the ISO automatically up to a maximum
200, but allows exposure times as long as 2 seconds, delivering usable
exposures at light levels as low as 1/8 foot-candle. The camera tends
to underexpose slightly under very dim lighting, even when the light levels
are within a range matching its available exposure times. Exposure compensation
seems to have only a slight effect, particularly in Night Landscape mode.
This may be deliberate, an attempt to keep the camera from blowing out
bright parts of night scenes too badly. Autofocus performance is very
good under low-light conditions, as the camera focused well in my tests
down to 1/16 foot-candle, even without its autofocus-assist illuminator,
and will focus on nearby subjects in total darkness when the assist illuminator
is turned on. Given that average city street lighting at night equates
to a light level of roughly 1 foot-candle though, the Coolpix 5200 should
do fine for most night shots in "civilized" areas. Color balance
was slightly warm, with increased warmth at the lower exposures. Noise
is low, and only moderate even at ISO 400. The 5200's Noise Reduction
setting does a good job of controlling it however, as noise is much stronger
without it. The table below shows the best exposure I was able to obtain
for each of a range of illumination levels. Images in this table (like
all sample photos) are untouched, exactly as they came from the camera.
(Note: If you'd like to use a light meter to
check light levels for subjects you might be interested in shooting, a
light level of one foot-candle corresponds to a normal exposure of two
seconds at f/2.8 and ISO 100.)

Flash Range Test
A powerful flash, without very little falloff throughout the test
range.
In my testing, the 5200's flash illuminated the test target quite well
all the way out to 14 feet, with very little decrease in image brightness.
Below is the flash range series, with distances from eight to 14 feet
from the target.
Very high resolution, 1,300 lines of "strong detail." Very
high barrel distortion at the wide angle lens setting.
The 5200 performed well on the "laboratory" resolution test
chart. It started showing artifacts in the test patterns at resolutions
as low as 1,000 lines per picture height, in both horizontal and vertical
directions. I found "strong detail" out to at least 1,300 lines
vertically, and slightly more horizontally. "Extinction" of
the target patterns didn't occur until 1,600 - 1,700 lines. (Some reviewers
will doubtless assign higher resolution numbers to the Coolpix 5200, but
I hold to a more conservative approach in judging resolution, feeling
that one shouldn't claim "resolution" beyond the point at which
the artifacts swamp the subject details. Hence my judgement of 1,300 lines
for the 5200's resolution, even though at least some vestige of the target
lines can be seen at 1,400 lines or higher.)
Geometric distortion on the 5200 is quite a bit higher than average at
the wide-angle end, where I measured approximately 1.2 percent barrel
distortion. The telephoto end fared much better, as I found only 0.03
percent barrel distortion (about one pixel) there. Chromatic aberration
is very low, showing only very faint coloration on either side of the
target lines. (This distortion is visible as a very slight colored fringe
around the objects at the edges of the field of view on the resolution
target.) There is some softness in the corners and along the right edge
of the frame, particularly in the telephoto res target shot.
An accurate LCD monitor, but very tight optical viewfinder.
The 5200's optical viewfinder is very tight, showing only about 72
percent frame accuracy at wide angle, and about 76 percent at telephoto.
The LCD monitor proved much more accurate, showing about 97 percent
accuracy at wide angle, and about 99 percent at telephoto. Given that
I like LCD monitors to be as close to 100 percent accuracy as possible,
the 5200's LCD monitor does a good job here, but the optical viewfinder's
performance is very poor indeed. Flash distribution is fairly even at
wide angle, with just a little falloff at the corners and edges of the
frame. At telephoto, flash distribution is more uniform.
