Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3000 and the Panasonic Lumix DMC-G10? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Nikon D3000 and the Panasonic G10 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G10 is notably smaller (15 percent) than the Nikon D3000. Moreover, the G10 is markedly lighter (28 percent) than the D3000. In this context, it is worth noting that neither the D3000 nor the G10 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D3000) and the Micro Four Thirds Lens Catalog (G10). Mirrorless cameras, such as the G10, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D3000 gets 500 shots out of its Nikon EN-EL9a battery, while the G10 can take 380 images on a single charge of its Panasonic DMW-BLB13 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G10 was launched at a somewhat lower price (by 17 percent) than the D3000, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D3000 features an APS-C sensor and the Panasonic G10 a Four Thirds sensor. The sensor area in the G10 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D3000 has a native 3:2 aspect ratio, while the one in the G10 offers a 4:3 aspect.

Despite having a smaller sensor, the G10 offers a higher resolution of 12 megapixels, compared with 10 MP of the D3000. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.33μm versus 6.11μm for the D3000). However, it should be noted that the G10 is a somewhat more recent model (by 7 months) than the D3000, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Panasonic G10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G10 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Nikon D3000 are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.

The Nikon D3000 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-G10 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the D3000 is build around a CCD sensor, while the G10 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the D3000 has a notably higher overall DXO score than the G10 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 1 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G10 indeed provides for movie recording, while the D3000 does not. The highest resolution format that the G10 can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G10 has an electronic viewfinder (202k dots), while the D3000 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the G10 offers a wider field of view (100%) than the one in the D3000 (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the D3000 has a higher magnification (0.53x vs 0.52x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3000 and Panasonic G10 in connection with corresponding information for a sample of similar cameras.

Both the D3000 and the G10 have been discontinued, but can regularly be found used on ebay. The D3000 was replaced by the Nikon D3100, while the G10 was followed by the Panasonic G3. Further information on the features and operation of the D3000 and G10 can be found, respectively, in the Nikon D3000 Manual (free pdf) or the online Panasonic G10 Manual.

Review summary

So how do things add up? Is the Nikon D3000 better than the Panasonic G10 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Nikon D3000:

• Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.52x).
• Faster burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (500 versus 380) on a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in July 2009).

Reasons to prefer the Panasonic Lumix DMC-G10:

• More detail: Has more megapixels (12 vs 10MP), which boosts linear resolution by 7%.
• Broader imaging potential: Can capture not only stills but also 720/30p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• More compact: Is smaller (124x84mm vs 126x97mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 148g or 28 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
• More modern: Was introduced somewhat (7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G10 comes out slightly ahead of the D3000 (10 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Nikon D3000 and the Panasonic G10 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D3000 and the G10 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
