The Konica Minolta DiMAGE G500 is one of the first products to ship, following the merger between Konica and Minolta in 2003. The Konica Minolta DiMAGE G500 is actually little more than a rebadged Konica KD-510Z, a product developed by Konica before the merger took effect.. With 5.0 megapixels, a 3x optical zoom lens, and a compact, all-metal body with fully retracting lens, the G500 has the profile of an excellent travel companion. The benefit of automatic or full manual exposure control ought to please a range of user levels, and the flexibility of image color, sharpness, and a range of exposure adjustments will satisfy the needs of more experienced users.
Minolta's latest DiMAGE digicam bears a striking resemblance to the Konica KD-510Z digital camera, no surprise, since it's essentially the same camera with a new logo. Thanks to a merger between the two companies, the DiMAGE G500 is simply Minolta's repackaging of the previous Konica model. The dual-slot digicam accepts both SD memory cards and Sony Memory Sticks, a feature that first debuted on the Konica KD-400. Adding to the G500's attractions are its tiny size and stainless steel alloy body, as well as a high-resolution, five-megapixel CCD. Compact and rugged, the G500 should stand up to heavy usage, another bonus when traveling. The sliding lens cover design eliminates the need for a lens cap, and keeps the camera front smooth and pocket-friendly. Small enough for the average shirt pocket, the G500 comes with a wrist strap for easy toting. The 3x zoom lens and 5.0-megapixel CCD capture high resolution, print quality images, with great color and detail. With high-tech simplicity and ease-of-use forefront in the G500's design, the camera's point-and-shoot operation is quick to learn and convenient.
Equipped with a telescoping, 3x, 8-24mm Hexanon lens (39-117mm 35mm equivalent), the G500's tiny size doesn't compromise its optics. Focus remains under automatic control, and ranges from 1.64 feet (0.5 meters) to infinity in normal mode, and from 2.36 inches (6 centimeters) to infinity in Macro mode. (The G500's macro capabilities are pretty good, its minimum macro area is a fairly small 2.85 x 2.14 inches or 72 x 54 millimeters.) Apertures range from f/2.8 to f/8.3, with actual values depending on the zoom setting. A green AF illuminator light strip on the front of the camera shines a (somewhat dim) light on the subject when shooting in low-light situations, and lights up playfully when the camera is powered on. In addition to the camera's 3x optical zoom, as much as 3x digital zoom is also available, effectively increasing the G500's zoom capabilities to 9x. (I always remind readers though, that digital zoom typically decreases the overall image quality because it simply enlarges the center pixels of the CCD image. Resulting images generally have softer details and higher noise levels.) Both a real-image optical viewfinder and 1.5-inch color LCD monitor are available for composing images. The unusually bright and contrasty LCD monitor features an information display that reports limited camera settings information, including the shutter speed and aperture settings (when the Shutter button is halfway pressed).
The G500 offers either full manual or full automatic exposure control (the Manual setting is accessed through the Record menu). Limited external controls keep the user interface simple, but also mean greater reliance on the LCD menu system. That said, the G500's LCD menus are straightforward and uncomplicated, with a scrolling page layout. The sliding lens cover serves as the power switch, triggering the lens to extend forward when opened. Macro, Self-Timer, and Distant View (landscape) photography modes are accessed via the left arrow of the Four-Way Arrow pad. By default, the G500 employs a TTL center-weighted metering system, but a Spot metering option is available through the Record menu. An Exposure Compensation adjustment lightens or darkens the overall image from -1.5 to +1.5 exposure equivalents (EV) in one-third-step increments. Shutter speeds range from 1/2,000 to one second in normal shooting mode, but the Slow Shutter option and Manual record mode offer maximum exposure times up to 15 seconds. The camera's White Balance adjustment offers Auto, Daylight, Cloudy, Fluorescent, and Tungsten options, for shooting under different light sources. You can also opt to record images in Black-and-White or Sepia monotones. The G500's built-in flash operates in Auto, Forced, Red-Eye Reduction, Suppressed, and Slow-Sync modes. A menu option lets you control flash power, from -1 to +1 EV.
The G500 also features a Movie mode, activated through the Record menu. The camera captures moving images with sound for as long as 30 seconds per clip, at 320 x 240 pixels. (The amount of available memory card space also determines the length of movie files.) As with most cameras offering sound recording with their movie options, you can set the G500's lens to whatever zoom position you like prior to the start of recording, but once recording has begun, the focal length is fixed. This prevents the noise of the zoom motor from affecting the audio track. You can also record short sound clips to accompany images, for a maximum of 30 seconds (or as long as the memory card has available space.) Audio clips can be recorded with an image or anytime afterwards. A Continuous shooting mode is hidden in the camera's Setup menu, and once activated, shoots a rapid sequence of images for as long as the Shutter button is held down. The camera's Self-Timer mode offers a short delay (either three or 10 seconds) between the time the Shutter button is pressed and the shutter actually opens, giving you time to zip around in front of the camera for a self-portrait. Through the Record menu, the G500 also offers an ISO adjustment, with equivalent settings of 50, 100, 200, and 400. Contrast, Sharpness, and Saturation can also be adjusted, as well as the individual red, blue, and green levels.
As I mentioned above, the G500 stores images either on Sony Memory Sticks or on SD/MMC memory cards, both available separately in a variety of storage capacities. A 16MB SD card ships with the camera, but I'd recommend picking up a higher-capacity card, especially given the camera's maximum 2,592 x 1,944-pixel resolution. Two megabytes of internal flash memory provide a small buffer that temporarily saves images, and that permits the copying files between memory cards. The camera utilizes a rechargeable DR-LB4 lithium battery pack for power, which comes with the camera, along with a battery charger. (An AC adapter is available as a separate accessory, and uses a "dummy" battery to plug into the camera.) The G500 features a USB jack and cable for downloading images to a computer. Two CD-ROMs also come with the camera, one loaded with DiMAGE Viewer software for downloading and organizing images, and the other loaded with the instruction manuals. (The necessary USB drivers are also provided.)
At the end of the day, the DiMAGE G500 is a very competent little camera, my main criticism of it being a very sluggish shutter response. While compact digicams often have shutter lag times (the delay between pressing the shutter and the camera actually snapping the picture.) on the slow side of average, the G500's 1.30-1.45 second shutter delay range was quite a bit longer than that of other contenders. Apart from this, the G500 performed nicely in my tests.

Recommendation
With its dual-format memory card slot, tiny size, and simple, point-and-shoot operation, Minolta's DiMAGE G500 is a rugged, portable option for techno-savvy consumers. Accepting both SD/MMC cards and Sony Memory Sticks, the G500 is geared toward those consumers who want to make the most of their techno-gadgets by throwing a very compact digicam into the mix. The camera's stainless steel alloy body is perfect for travel, as is the small size and pocket-friendly design. The 5.0-megapixel CCD and 3x optical zoom are enough to satisfy advanced pros looking for a general-purpose camera with great image quality, and the option for automatic or full manual exposure control welcomes a range of experience levels.
Trim, compact, and light weight, the G500 is ready for travel. Its stainless steel alloy body can withstand some wear and tear, and the very small size is perfect for pockets. The sliding lens cover keeps the front panel smooth whenever the camera is shut off, making it easy to stash it in a pocket at a moment's notice. Measuring 3.75 x 2.25 x 1.19 inches (94 x 56 x 29.5 millimeters), the G500's easily pocketable, though its thickness and semi-sharp edges are better for a purse or bag. Despite its metal body, the camera remains light weight at just 7.1 ounces (200 grams) without the battery or memory card. A wrist strap secures the camera while in-hand. Those wanting to maintain its nice sheen should get a soft case.
The G500's front panel is fairly smooth with the lens cover closed, with the exception of some very small protrusions. Sliding open the lens cover triggers the 3x zoom lens to telescope outward into its shooting position. I'm accustomed to sliding lens covers opening from left to right, but the G500's operates in the opposite direction, which took some getting used to. The lens comes out very quickly, in under one second, and the camera can capture its first shot in as little as 1.6 seconds after being turned on. In addition to the lens, the camera's flash, optical viewfinder window, AF assist lamp, and a small light sensor are also beneath the sliding cover. The thin, horizontal AF assist lamp below the lens shines a cool green when lit, adding to the G500's stylish features. Though the camera doesn't have much of a hand grip, a sculpted, curving ridge on the front panel serves as a finger grip, reinforced by a slight thumb rest on the back panel.
On the right side of the camera is an eyelet for attaching the wrist strap, as well as the USB jack.
The opposite side of the camera is smooth and flat. At the very bottom of the panel is a small, removable section of the battery compartment. This provides an opening for the AC adapter cord, which attaches to a "dummy" battery.
A smooth, flat Shutter button and the camera's microphone are the only features on the top panel, which is also very flat.
The remaining camera controls are on the rear panel, along with the LCD monitor and optical viewfinder. The tiny optical viewfinder eyepiece doesn't have a diopter adjustment, but does have a moderate eyepoint. I could see the full view a short distance from the eyepiece, so eyeglass wearers may be more comfortable framing images with the LCD monitor. Two LED lamps on the right side of the eyepiece light or blink to indicate camera status, such as when focus is set or the flash is charging. The Playback, Display, Erase, and Zoom buttons flank the eyepiece. Just below the Zoom buttons (which are in the top right corner) is the camera's speaker. The 1.5-inch color LCD monitor dominates the left side of the back panel, and directly to the right of it are the Menu/Set and Four-Way Arrow pad rocker buttons.
The G500's bottom panel is also smooth and flat. A plastic threaded tripod mount sits to the far right (when looking from the back), which may encourage the camera to sit slightly tilted on a tripod head. (This is easily remedied by tilting the tripod head itself, but I thought it worth mentioning.) Also on the bottom panel is the battery and memory card slot, covered by a sliding, hinged door. The slot houses both Sony Memory Sticks and SD/MMC memory cards, as well as a lithium-ion battery pack. While I lacked the necessary power connector to perform my usual battery-life tests, it bears mentioning that the battery life of the G500's Konica-branded sibling was amazing, often sitting for over a month and still operating for several hours of on time. This is a good trait for a "purse camera."
The G500's limited external controls make it less daunting to approach than more complicated control layouts, but also mean that you'll need to access the LCD menu system to change most camera settings. Still, the external controls offer basic image erase, flash mode, and capture mode functions, about all that the typical point & shoot user will need for normal operation. The LCD menu system is fairly straightforward, with about two to three pages of options per menu. The arrow keys scroll through menu items, and you can easily exit the menus by pressing the left arrow until the main LCD display returns. Because of the camera's point-and-shoot nature, you'll likely spend more time shooting than sifting through menu items. Given the fairly intuitive user interface, it shouldn't take more than a few minutes to get the gist of things. A hardcopy Quick Guide is all you'll need to get up and running, though a full copy of the instruction manual accompanies the camera on CD-ROM.
Record
Mode Display: In Record mode, the G500's LCD reports the type of memory
card in use, date and time, level of battery power, number of available images,
and the file resolution and quality settings. When the Shutter button is halfway
pressed, the display also reports the selected aperture and shutter speed settings
(in auto mode). Pressing the Display button once cancels the information display,
while a second turns off the LCD monitor entirely. A third press restores the
default display.
Playback
Mode Display: In Playback mode, the LCD reports the file name, series
number, date and time, type of memory card, and the resolution and quality settings.
Pressing the Display button simply dismisses and recalls the information display.
A Playback zoom feature is available using the Zoom controls, as is a nine-image
index display.
External Controls
Sliding Lens Cover: Sliding from right to left across the front of the camera, the lens cover acts as the power switch and enables the lens to telescope forward when slid fully open. Closing the cover signals the lens to retract, and shuts off the camera.
Shutter Button: Located on the far right side of the top panel, this button
sets focus and exposure when halfway pressed, and fires the shutter when fully
pressed.
Wide and Tele Zoom Buttons: Positioned in the top right corner of the camera's
back panel, these buttons control the optical and digital zoom in Record mode.
In Playback mode, these buttons control the digital enlargement of captured images.
Erase Button: Directly to the left of the viewfinder eyepiece on the back
panel, this button erases a single image in Playback mode. If pressed in Record
mode, the most recently captured image is displayed with an option to erase
it.
Display Button: To the left of the Erase button, this button controls the
LCD display mode in Record and Playback modes, cycling through information displays
and disabling the LCD itself.
Playback Button: The far left control on the camera's back panel, this button
activates Playback mode while the camera is in Record mode. If the camera is
powered off, pressing and holding this button activates the camera in Playback
mode. A second press shuts the camera off.
Menu / Set Button: Adjacent to the bottom right corner of the LCD monitor,
this button activates the LCD menu in any mode. It also confirms menu selections.
Four Way Arrow Pad: Just to the right of the Menu / Set button, this rocker-style
arrow pad has four arrows, one in each direction. Through the Setup menu, the
arrow keys can be programmed to handle a few other functions. In any settings
menu, these arrows navigate through menu selections.
In Record mode, the left arrow cycles through the available capture modes: Macro, Distant View, Self-Timer, Self-Timer with Macro, and Self-Timer with Distant View. The right arrow key controls the flash mode, cycling through Auto, Red-Eye Reduction, Forced, Slow-Sync, and Suppressed modes. If Manual exposure mode has been enabled, the up and down arrows control aperture, while the left and right arrows adjust shutter speed.
In Playback mode, the left and right keys scroll through captured images on the memory card. When an image has been enlarged, all four arrow keys move around within the enlarged view. In normal display mode, the up arrow displays exposure information, such as shutter speed, lens aperture, flash mode, and file size.
Camera Modes and Menus

Just as important as an extra memory card is a tool to rescue your images when one of your cards fails at some point in the future. I get a lot of email from readers who've lost photos due to a corrupted memory card. Memory card corruption can happen with any card type and any camera manufacturer, nobody's immune. A surprising number of "lost" images can be recovered with an inexpensive, easy to use piece of software though. Given the amount of email I've gotten on the topic, I now include this paragraph in all my digicam reviews. The program you need is called PhotoRescue, by DataRescue SA. Read our review of it if you'd like, but download the program now, so you'll have it. It doesn't cost a penny until you need it, and even then it's only $29, with a money back guarantee. So download PhotoRescue for Windows or PhotoRescue for Mac while you're thinking of it. (While you're at it, download the PDF manual and quickstart guide as well.) Stash the file in a safe place and it'll be there when you need it. Trust me, needing this is not a matter of if, but when... PhotoRescue is about the best and easiest tool for recovering digital photos I've seen. (Disclosure: IR gets a small commission from sales of the product, but I'd highly recommend the program even if we didn't.) OK, now back to our regularly scheduled review...

Test Results
In keeping with my standard test policy, the comments given here summarize only
my key findings. For a full commentary on each of the
test images, see the DiMAGE G500's "pictures" page. For a
selection of more "pictorial" images, check out the G500's
Photo Gallery.
Not sure which camera to buy? Let your eyes be the ultimate judge! Visit our Comparometer(tm) to compare images from the G500 with those from other cameras you may be considering. The proof is in the pictures, so let your own eyes decide which you like best!
As with all Imaging Resource product tests, I encourage you to let your own eyes be the judge of how well the camera performed. Explore the images on the pictures page, to see how the G500's images compare to other cameras you may be considering.
- Color: Pretty good color, but some color casts from
the white balance system. Overall, the G500 did a pretty good job with
color, though I noticed slight warm and reddish color casts in most shots.
Saturation was typically about right, though bright reds were definitely a
little hot, especially in the Outdoor Portrait. The camera was also thrown
off by the large amount of blue in the composition of the Musicians poster,
which resulted in stronger reddish color casts. Indoors, the camera had some
trouble with the incandescent lighting, producing a rather pinkish cast. That
said, the outdoor house shot, House poster, and Macro shot all had nearly
accurate color. Skin tones were about right in the Outdoor Portrait shot,
though slightly pink, and the blue flowers there were about right. The large
color blocks of the "Davebox" test were a bit warm, but overall
saturation here was pretty good (just a little strong in the additive primary
color blocks).
- Exposure: Generally accurate exposure. High contrast
under harsh lighting, good contrast otherwise. The G500's exposure system
did a pretty good job throughout my testing, exposing my test targets, both
indoors and out, pretty well. The camera produced high contrast under the
harsh lighting of the Outdoor Portrait, though the subtle contrast adjustment
did a reasonably good job of bringing up the midtones. Shadow detail was typically
good, and the camera handled the harsh highlights of the outdoor house shot
pretty well. On my "Davebox" test, the G500 distinguished the subtle
pastel tones on the Q60 target well. The indoor portraits required an average
amount of exposure compensation, though the Outdoor Portrait needed slightly
more than average.
- Resolution/Sharpness: High resolution, 1,300-1,350 lines
of "strong detail." The G500 performed very well on my "laboratory"
resolution test chart. Test patterns in both horizontal and vertical directions
looked clean and clear as far as 900 lines, and even the artifacts that did
show up were very minor. (Artifacts were strongest in the horizontal test
patterns.) I found "strong detail" out to 1,300-1,350 lines, though
vertically, you could argue for higher. (I suspect some reviewers would rate
the G500's resolution here as high as 1,500 lines or more, but I tend to be
a bit more conservative in my resolution ratings than some, feeling that resolution
shouldn't be counted past the point where artifacts compete strongly with
genuine subject detail.) "Extinction" of the target patterns didn't
occur until about 1,700 lines.
- Closeups: A small minimum macro area, with good detail.
Flash is blocked by the lens in the closest shots though. The G500 performed
pretty well in the macro category, capturing a minimum area of only 2.85 x
2.14 inches (72 x 54 millimeters). Resolution was very high, showing a lot
of fine detail in the dollar bill. However, the coins and brooch were soft
due to the very short shooting distance (and probably some corner softness
as well). There was also a fair bit of softness in the corners on the left
side of the frame. The position of the G500's flash directly above the lens
resulted in a dark shadow in the lower portion of the frame, so I'd recommend
using an external light source for macro shots.
- Night Shots: Good low-light performance, with usable
images at the lowest light level of my test. The G500 has a manual exposure
mode, adjustable ISO setting, and a maximum exposure time of 15 seconds. As
you'd expect then, the camera performed well on my low-light test, capturing
bright, usable images down to the 1/16 foot-candle (0.67 lux) limit of my
test, at all four ISO settings. (The ISO 50 image was just slightly dim at
this lowest light level, but still somewhat usable, and could potentially
be brightened post-capture, in software.) The G500 automatically applies Noise
Reduction on exposures longer than 1/2-second. However, I still found noise
levels a little higher than I'd like at the ISO 200 and 400 settings, especially
with the longer exposures. Color is pretty good overall with the Auto white
balance, though the dim lighting resulted in a reddish cast.
- Viewfinder Accuracy: A tight optical viewfinder, but
good accuracy from the LCD monitor. The G500's optical viewfinder is a
little tight, showing 83 percent of the final frame at both wide angle and
telephoto zoom settings. The LCD monitor proved much more accurate in some
respects, showing 98 percent frame accuracy at both zoom settings. However,
images framed with the LCD monitor were just slightly cut off at the very
left of the frame, so I'd recommend nudging in just a little extra space when
tight framing is key. Still, given that I like LCD monitors to be as close
to 100 percent accuracy as possible, the G500's LCD monitor performed pretty
well here.
- Optical Distortion: Slightly higher than average geometric
distortion, about average chromatic aberration. Optical distortion on
the G500 was slightly high at the wide-angle end, where I measured approximately
0.9 percent barrel distortion. The telephoto end fared much better, as I measured
0.2 percent barrel distortion there. Chromatic aberration looked to be about
average, as there was moderately strong coloration visible 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.)
- Battery Life: No explicit battery-life test on this
model, but plan on buying a second battery. I didn't have the necessary
power adapter to measure the G500's power consumption directly, but my impression
of its battery life was that it was fairly short (typical for a compact camera
model), so my usual advice to purchase a second battery along with the camera
definitely applies here. (On the other hand, it seems to be able to sit in
its "sleeping" mode for quite a long time, without draining the
battery noticeably.
With the DiMAGE G500, Minolta took a clever Konica digicam, the KD-510Z, and
repackaged it with the popular DiMAGE name. The camera's innovative design is
flexible in its acceptance of both SD/MMC cards and Sony Memory Sticks for image
storage, and the rugged, stainless steel body can withstand heavy usage. The
5.0-megapixel CCD and true, 3x optical zoom lens ensure high quality images
with great color and detail, and the simple user interface should appeal to
a wide audience, from novice to experienced pro. All controls are smooth, from
the slick sliding door to the onscreen performance, with fast zoom and easy
menu navigation. The LCD is unusually bright, with excellent contrast and daylight
viewability. All in all, a nice little digicam, bit its rather sluggish
shutter response kept it from being chosen as a Dave's
Pick.
