Panasonic G3 vs LX7
The Panasonic Lumix DMC-G3 and the Panasonic Lumix DMC-LX7 are two digital cameras that were announced, respectively, in May 2011 and July 2012. The G3 is a mirrorless interchangeable lens camera, while the LX7 is a fixed lens compact. The cameras are based on a Four Thirds (G3) and a 1/1.7-inch (LX7) sensor. The G3 has a resolution of 15.8 megapixels, whereas the LX7 provides 10 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-G3 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.
An illustration of the physical size and weight of the Panasonic G3 and the Panasonic LX7 is provided 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 G3 can be obtained in four different colors (black, brown, red, white), while the LX7 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 Panasonic LX7 is notably smaller (22 percent) than the Panasonic G3. In this context, it is worth noting that neither the G3 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 G3 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 G3 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. The LX7 was launched at a lower price than the G3, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic G3 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 15.8MP, the G3 offers a higher resolution than the LX7 (10MP), but the G3 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 2.05μm for the LX7) due to its larger sensor. However, the LX7 is a somewhat more recent model (by 1 year and 2 months) than the G3, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
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 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-G3 has a native sensitivity range from ISO 160 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.
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"). Of the two cameras under review, the G3 has a notably higher overall DXO score than the LX7 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 1.1 EV of lower dynamic range, and 2.2 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX7 provides a faster frame rate than the G3. It can shoot movie footage at 1080/60p, while the G3 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range 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 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 following table reports on some other key feature differences and similarities of the Panasonic G3, the Panasonic LX7, and comparable cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3 has a touchscreen, while the LX7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the LX7 does not have a selfie-screen.
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 G3 and the LX7 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-G3 and Panasonic Lumix DMC-LX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G3 and the LX7 have been discontinued, but can regularly be found used on eBay. The G3 was replaced by the Panasonic G5, while the LX7 was followed by the Panasonic LX10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So how do things add up? Which of the two cameras – the Panasonic G3 or the Panasonic LX7 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Panasonic Lumix DMC-G3:
- More detail: Offers more megapixels (15.8 vs 10MP) with a 26% higher linear resolution.
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (2.2 stops ISO advantage).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More heavily discounted: Has been on the market for longer (launched in May 2011).
Reasons to prefer the Panasonic Lumix DMC-LX7:
- More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
- Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- Faster burst: Shoots at higher frequency (11 vs 4 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 G3 necessitates an extra lens.
- More compact: Is smaller (111x68mm vs 115x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the G3).
- Longer lasting: Gets more shots (330 versus 270) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- 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 LX7 is the clear winner of the contest (13 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 G3 or the LX7 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
