Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G10 and the Panasonic Lumix DMC-LX7? 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 G10 and the Panasonic LX7 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The LX7 can be obtained in two different colors (black, 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 LX7 is notably smaller (28 percent) than the Panasonic G10. In this context, it is worth noting that neither the G10 nor the LX7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 has a lens built in, whereas the G10 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the G10 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G10 gets 380 shots out of its Panasonic DMW-BLB13 battery, while the LX7 can take 330 images on a single charge of its Panasonic DMW-BCJ13 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. 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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic G10 features a Four Thirds sensor and the Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 81 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 4.65. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

With 12MP, the G10 offers a higher resolution than the LX7 (10MP), but the G10 nevertheless has larger individual pixels (pixel pitch of 4.33μm versus 2.05μm for the LX7) due to its larger sensor. However, the LX7 is a much more recent model (by 2 years and 4 months) than the G10, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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 Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 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-LX7 are ISO 80 to ISO 6400, with the possibility to increase the ISO range to 80-12800.

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 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LX7 provides a better video resolution than the G10. It can shoot movie footage at 1080/60p, while the G10 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G10 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the LX7 relies on live view and the rear LCD for framing. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The table below summarizes some of the other core capabilities of the Panasonic G10 and Panasonic LX7 in connection with corresponding information for a sample of similar cameras.

The Panasonic LX7 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the G10 and the LX7 write their files to SDXC 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-G10 and Panasonic Lumix DMC-LX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G10 and the LX7 have been discontinued, but can regularly be found used on ebay. The G10 was replaced by the Panasonic G3, while the LX7 was followed by the Panasonic LX10. Further information on the features and operation of the G10 and LX7 can be found, respectively, in the Panasonic G10 Manual (free pdf) or the online Panasonic LX7 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Panasonic G10 and the Panasonic LX7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Panasonic Lumix DMC-G10:

• More detail: Offers more megapixels (12 vs 10MP) with a 10% higher linear resolution.
• Better low-light sensitivity: Requires less light for good images (1.5 stops ISO advantage).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (380 versus 330) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in March 2010).

Reasons to prefer the Panasonic Lumix DMC-LX7:

• More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
• Faster burst: Shoots at higher frequency (11 vs 2.6 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the G10 necessitates an extra lens.
• More compact: Is smaller (111x68mm vs 124x84mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the G10).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More modern: Reflects 2 years and 4 months of technical progress since the G10 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the LX7 is the clear winner of the contest (11 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 LX7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G10 or the LX7 perform in practice. 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 hands-on reviews by experts 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
