Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G3 and the Sony ZV-E10? 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

The physical size and weight of the Panasonic G3 and the Sony ZV-E10 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 size dimensions are rounded to the nearest millimeter.

The G3 can be obtained in four different colors (black, brown, red, white), while the ZV-E10 is available in two color-versions (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony ZV-E10 is notably smaller (24 percent) than the Panasonic G3. However, the ZV-E10 is slightly heavier (2 percent) than the G3. In this context, it is worth noting that neither the G3 nor the ZV-E10 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 Micro Four Thirds Lens Catalog (G3) and the Sony E-Mount Lens Catalog (ZV-E10). 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.

Concerning battery life, the G3 gets 270 shots out of its Panasonic DMW-BLD10 battery, while the ZV-E10 can take 440 images on a single charge of its Sony NP-FW50 power pack. The power pack in the ZV-E10 can be charged via the USB port, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G3 was launched at a somewhat lower price (by 14 percent) than the ZV-E10, 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 imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G3 features a Four Thirds sensor and the Sony ZV-E10 an APS-C sensor. The sensor area in the ZV-E10 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the G3 has a native 4:3 aspect ratio, while the one in the ZV-E10 offers a 3:2 aspect.

With 24MP, the ZV-E10 offers a higher resolution than the G3 (15.8MP), but the ZV-E10 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.77μm for the G3) due to its larger sensor. Moreover, the ZV-E10 is a much more recent model (by 10 years and 2 months) than the G3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony ZV-E10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZV-E10 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic G3 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The ZV-E10 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Panasonic Lumix DMC-G3 has a native sensitivity range from ISO 160 to ISO 6400. The corresponding ISO settings for the Sony ZV-E10 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-51200.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the ZV-E10 provides a better video resolution than the G3. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G3 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the ZV-E10 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic G3 and Sony ZV-E10 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The G3 has one, while the ZV-E10 does not. While the built-in flash of the G3 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the ZV-E10 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The G3 writes its imaging data to SDXC cards, while the ZV-E10 uses SDXC or Memory Stick PRO Duo cards. The ZV-E10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G3 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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-G3 and Sony ZV-E10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the ZV-E10 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G3 does not provide wifi capability.

The ZV-E10 is a recent model that features in the current product line-up of Sony. In contrast, the G3 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G3 was succeeded by the Panasonic G5. Further information on the features and operation of the G3 and ZV-E10 can be found, respectively, in the Panasonic G3 Manual (free pdf) or the online Sony ZV-E10 Manual.

Review summary

So how do things add up? Which of the two cameras – the Panasonic G3 or the Sony ZV-E10 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Panasonic Lumix DMC-G3:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.

If the count of relative strengths (bullet points above) is taken as a measure, the ZV-E10 is the clear winner of the contest (21 : 4 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 G3 and the Sony ZV-E10 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 G3 and the ZV-E10 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 adjacent summary-table relays the overall verdicts of several of the most popular 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
