Digital Cameras - Panasonic Lumix DMC-FZ3 Test Images
|I've begun including links in our reviews to a Thumbnail index page for the test shots. The data on this page includes a host of information on the images, including shutter speed, ISO setting, compression setting, etc. Rather than clutter the page below with all that detail, we're posting the thumbnail index so only those interested in the information need wade through it!|
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 Lumix DMC-FZ3 did a pretty good job in this respect.
The shot at right was taken with a +0.3 EV exposure compensation adjustment, which is a little less than is usually required here. The FZ3 does a surprisingly good job of holding onto the highlight detail in Marti's shirt here, particularly for a camera without a contrast adjustment option. Though slightly reddish, I chose the Auto white balance setting for the main series. The Daylight setting resulted in a stronger red cast, and the Manual setting produced a yellow image.
Marti's skin tones are here are just slightly reddish, but very close to the mark, and the blue flowers in the bouquet are a bit more purplish than in real life. (Many digicams have trouble with this blue, which is in reality a light navy blue with just hints of purple in it.) The greens and yellows in the bouquet are also a little dark, but the red flowers are bright and vibrant, perhaps just slightly oversaturated. Resolution is high, and detail is strong in the flower bouquet, as well as in the creases of the fabric background. Shadow detail is moderate, with relatively low image noise. An excellent job overall, with this tough subject.

Excellent resolution and detail, though again high contrast.
Exposure and color balance are similar to the wider shot above, and contrast is slightly high. The shot at right was taken at the default exposure setting. Highlights are bright, but have good detail, though the midtones are slightly dark. The DMC-FZ3's 12x Leica zoom lens helps prevent geometric distortion of Marti's features, and captures sharp details. Resolution and detail are much stronger in this close-up shot, with great definition in Marti's face and hair.

through FZ3OUTFACAP2.HTM on the thumbnail index page.
Indoor Portrait, Flash:
Only a slight underexposure at the default flash setting, and very good color.
The DMC-FZ3's flash has low intensity at the default exposure setting, resulting in cool overall color. While the color balance remains slightly cool, flash performance is better with a +0.3 EV exposure compensation boost. (This is less boost than most cameras require on this shot.) The resulting shot is well-exposed, with good detail in the highlights of Marti's shirt, and good skin tone on her face. I also shot with the camera's Slow-Sync flash mode, choosing an exposure compensation adjustment of +1.0 EV. At the lower exposures, an orange cast from the background incandescent lighting seems to dominate the image. Increasing the exposure compensation results in brighter highlights, but decreases the orange cast.

Indoor Portrait, No Flash:
Slightly cool-looking with the Manual setting, but good results overall, and better-than average exposure accuracy.
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 DMC-FZ3's Auto white
balance setting produced a slight reddish color balance that was just
a little too red for my taste, but that many users may actually prefer,
as being more representative of the warm room lighting. Instead, I chose
the slightly cooler color balance of the Manual
setting, as it appeared the most neutral. (The Incandescent
setting produced a warm, yellow color balance.) Skin tones are slightly
magenta, and the blue flowers are quite purple, no surprise, given the
lighting for this shot. - The FZ3 actually did very well with this shot,
much better than average. The main exposure was taken with a +0.7 EV exposure
compensation adjustment, which gave a good exposure overall, while still
holding detail in the highlights on Marti's shirt.
High resolution and strong detail, with pretty accurate color and good sharpness in the corners.
The DMC-FZ3's Auto white balance setting
produced the best overall color here, though the Daylight
setting also produced good results. The Manual
setting resulted in nearly accurate color as well, though the overall
color balance was cooler and less pleasing. Resolution is very high, as
the tree limbs above the roof and shrubbery in front of the house show
a lot of detail. The house trim and brick pattern also show a lot of fine
detail. Details are pretty sharp throughout the frame, with less of the
softening in the corners that I'm accustomed to seeing from consumer-level
Excellent resolution and detail, good sharpness corner to corner but the camera's overexposure limits the 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 DMC-FZ3 performed very well for its 3-megapixel class. The tree limbs over the roof and fine foliage in front of the house show strong detail, with good definition in the leaf and brick patterns. Details are also sharp across the entire frame, with very little of the softening in the corners that most digicams are prone to. The FZ3's in-camera sharpening does a good job here, with few halos or other sharpening artifacts. It did overexpose the shot a fair bit, which caused it to lose a lot of detail in the bright white paint surrounding the bay window, a trouble spot for many digicams. However, detail is a little stronger in the shadow area above the front door. The table below shows a standard resolution and quality series, followed by ISO and sharpness series.
Color Effect Series:
Lens Zoom Range
An excellent 12x zoom range.
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 (12x, in this case), and at full telephoto with the digital zoom enabled. The DMC-FZ3's Leica lens is equivalent to a 35-420mm zoom on a 35mm camera. That corresponds to an average wide angle to a very substantial telephoto. (And the anti-shake really helps you make the most of that long zoom.) Following are the results at each zoom setting.
Warm overall color, but good detail and 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 DMC-FZ3's Auto
and Daylight white balance settings produced
warm color balances, while the Manual setting
resulted in a cooler, slightly magenta cast. I settled on the Daylight
setting for the main shot, as the warm cast wasn't quite as strong. The
models' skin tones are quite warm, and the blue background has purplish
tints that aren't in the original image. The blue robe also has purplish
tints, in the deeper shadows. Resolution is very high, and detail is strong
throughout the frame. The bird wings on the blue robe are well-defined,
as are the instrument details, beaded necklaces, and petals in the flower
A very small macro area with excellent detail, but the flash is blocked by the lens when shooting this close.
The DMC-FZ3 performed very well in the macro category, capturing a minimum
area of only 1.6 x 1.2 inches (41 x 30 millimeters). Resolution is very
high, and the coins, brooch, and dollar bill show a lot of fine detail.
The coins and brooch are slightly soft due to the close shooting distance,
and also from some lens distortion that softens details toward the corner
of the frame (as evidenced in the top left corner). The camera's flash
is too far behind the lens to be effective here, and was mostly blocked
by the lens barrel. (Definitely plan on using external lighting for close-in
macro shots with the FZ3.)
"Davebox" Test Target
Nearly accurate color, and a good exposure.
Though it has just the slightest hint of a cool, magenta tint, the DMC-FZ3's
Manual white balance setting produced the best
overall color and white value here. The Auto
and Daylight settings both resulted in warmer
casts. Exposure looks about right, and the DMC-FZ3 does a good job distinguishing
the subtle tonal variations of the Q60 target. Colors are vibrant in the
large color blocks, and nearly accurate, with less oversaturation of the
red block than most cameras manage, but somewhat oversaturated blues.
- Overall very good accuracy though, with very few hue shifts. The shadow
area of the charcoal briquettes shows good detail, with moderate image
Color Effect Series:
About average low-light performance, with good color, better than average low-light focusing.
Equipped with an adjustable ISO setting and a maximum exposure time of eight seconds, the DMC-FZ3 performs about average in the low-light category. The camera produced clear, bright, usable images down to the 1/16 foot-candle (0.67 lux) limit of my test, with good color, only at the ISO 400 setting. At ISOs 80 and 100, images were bright as low as 1/4 foot-candle (2.7 lux), and at ISO 200, images were bright down to 1/8 foot-candle (1.3 lux). Given that average city street lighting at night corresponds to a light level of about one foot-candle though, the FZ3 should do just fine for most outdoor shooting at night under artificial lighting. Color was good with the Auto white balance setting. Image noise was low to moderate at the lower ISO settings, but increased quite a lot at ISO 400. The FZ3 focused down to a bit darker than 1/4 foot-candle with its autofocus illuminator turned off, and in complete darkness with the AF illuminator on. 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 moderately powerful flash, with some falloff at the 14 foot limit of this test.
In my testing, the DMC-FZ3's flash illuminated the test target all the
way out to 14 feet, though with decreasing intensity. The flash was still
effective at 14 feet, just dim. Below is the flash range series, with
distances from eight to 14 feet from the target.
High resolution, 1,050 lines of "strong detail." High barrel distortion, low pincushion, good corner sharpness, and very low chromatic aberration.
The DMC-FZ3 performed pretty well on the "laboratory" resolution test chart. It started showing artifacts in the test patterns at resolutions as low as 600~800 lines per picture height, in both horizontal and vertical directions. I found "strong detail" out to at least 1,100 lines horizontally, although only to about 1,000 lines in the vertical direction. "Extinction" of the target patterns occurred around 1,300 lines.
Optical distortion on the DMC-FZ3 is higher than average at the wide-angle
end, where I measured approximately 1.07 percent barrel distortion. The
telephoto end fared better, as I measured approximately 0.2 percent pincushion
distortion there. Chromatic aberration is quite low, with 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.) The corners of the images are
generally sharper than I'm accustomed to seeing in consumer digicams,
although at maximum telephoto, detail in the corners softens somewhat.
(Actually, the entire image is noticeably less crisp at full telephoto.)
Resolution Series, 50mm
Resolution Test, Zoom Series
Viewfinder Accuracy/Flash Uniformity
Excellent accuracy from the electronic viewfinder.
The DMC-FZ3's electronic "optical" viewfinder (EVF) is very accurate, showing about 98 percent frame accuracy at wide angle, and 99+ percent at telephoto. The LCD monitor is also very accurate, since it shows the same view, just on a larger screen. Given that I like LCD monitors to be as close to 100 percent accuracy as possible, the DMC-FZ3's LCD monitor performs well here. Flash distribution is fairly even at wide angle, with just a little falloff at the corners and edges of the frame. At full 12x telephoto, the flash is too weak and the studio lights were necessary for a bright exposure.
