Panasonic G10 vs G3
The Panasonic Lumix DMC-G10 and the Panasonic Lumix DMC-G3 are two digital cameras that were revealed to the public, respectively, in March 2010 and May 2011. Both the G10 and the G3 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G10 has a resolution of 12 megapixels, whereas the G3 provides 15.8 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G10 and the Panasonic Lumix DMC-G3? 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.
The physical size and weight of the Panasonic G10 and the Panasonic G3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The G3 can be obtained in four different colors (black, brown, red, white), while the G10 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G3 is notably smaller (7 percent) than the Panasonic G10. Moreover, the G3 is markedly lighter (13 percent) than the G10. In this context, it is worth noting that neither the G10 nor the G3 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G10 was launched at a somewhat lower price (by 17 percent) than the G3, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
While the two cameras under review share the same sensor size, the G3 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the G10. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the G3 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.33μm for the G10). However, it should be noted that the G3 is a somewhat more recent model (by 1 year and 2 months) than the G10, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The resolution advantage of the Panasonic G3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Panasonic G10 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Panasonic Lumix DMC-G10 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-G3 are ISO 160 to ISO 6400 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the G3 has a markedly higher DXO score than the G10 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.2 bits lower color depth, 0.5 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G3 provides a better video resolution than the G10. It can shoot movie footage at 1080/60i, while the G10 is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the G3 offers a substantially higher resolution than the one in the G10 (1440k vs 202k dots). The table below summarizes some of the other core capabilities of the Panasonic G10 and Panasonic G3 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3 has a touchscreen, while the G10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the G10 does not have a selfie-screen.
Concerning the storage of imaging data, both the G10 and the G3 write their files to SDXC cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-G10 and Panasonic Lumix DMC-G3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G10 and the G3 have been discontinued, but can regularly be found used on ebay. The G10 was replaced by the Panasonic G3, while the G3 was followed by the Panasonic G5. Further information on the features and operation of the G10 and G3 can be found, respectively, in the Panasonic G10 Manual (free pdf) or the online Panasonic G3 Manual.
So how do things add up? Is there a clear favorite between the Panasonic G10 and the Panasonic G3? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-G10:
- Longer lasting: Can take more shots (380 versus 270) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in March 2010).
Reasons to prefer the Panasonic Lumix DMC-G3:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 202k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.52x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (4 vs 2.6 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 52g or 13 percent) and is thus easier to take along.
- More modern: Was introduced somewhat (1 year and 2 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the G3 is the clear winner of the contest (12 : 3 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 Panasonic G10 and the Panasonic G3 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the G10 and the G3 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
