Going beyond this snapshot of core features and characteristics, what are the differences between the OM System Tough TG-7 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

An illustration of the physical size and weight of the OM System TG-7 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 size dimensions are rounded to the nearest millimeter.

The TG-7 can be obtained in two different colors (black, red), while the LX7 is also available in two color-versions, but different ones (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the OM System TG-7 and the Panasonic LX7 are of equal size. However, the LX7 is markedly heavier (20 percent) than the TG-7. It is worth mentioning in this context that the TG-7 is splash and dust resistant, while the LX7 does not feature any corresponding weather-sealing. More than that, the TG-7 is water-proof up to 15m and can, thus, be used for underwater photography.

The power pack in the TG-7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX7 was somewhat cheaper (by 9 percent) than the TG-7 at launch, but both cameras fall into the same price category. 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. 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. 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 OM System TG-7 features a 1/2.3-inch sensor and the Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 50 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 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.

Despite having a smaller sensor, the OM System TG-7 offers a higher resolution of 12 megapixels, compared with 10 MP of the Panasonic LX7. 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 1.53μm versus 2.05μm for the LX7). However, it should be noted that the TG-7 is much more recent (by 11 years and 1 month) than the LX7, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the OM System TG-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TG-7 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 OM System Tough TG-7 has a native sensitivity range from ISO 100 to ISO 12800. 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.

In terms of underlying technology, the TG-7 is build around a BSI-CMOS sensor, while the LX7 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 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. 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the TG-7 provides a higher video resolution than the LX7. It can shoot video footage at 4K/30p, while the Panasonic is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The TG-7 and the LX7 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. 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 OM System TG-7 and Panasonic LX7 in connection with corresponding information for a sample of similar cameras.

The OM System TG-7 and the Panasonic LX7 both have 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.

Both the TG-7 and the LX7 have zoom lenses built in. The TG-7 has a 25-100mm f/2.0-4.9 optic and the LX7 offers a 24-90mm f/1.4-2.3 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end than the OM System, but less tele-photo reach at the long end. The LX7 offers the faster maximum aperture.

Concerning the storage of imaging data, both the TG-7 and the LX7 write their files to SDXC cards. The TG-7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the LX7 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 OM System Tough TG-7 and Panasonic Lumix DMC-LX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the TG-7 offers wifi support, while the LX7 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Travel and landscape photographers will find it useful that the TG-7 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The TG-7 is a recent model that features in the current product line-up of OM System. In contrast, the LX7 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the LX7 was succeeded by the Panasonic LX10. Further information on the features and operation of the TG-7 and LX7 can be found, respectively, in the OM System TG-7 Manual (free pdf) or the online Panasonic LX7 Manual.

Review summary

So how do things add up? Is there a clear favorite between the OM System TG-7 and the Panasonic LX7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the OM System Tough TG-7:

• More detail: Offers more megapixels (12 vs 10MP) with a 10% higher linear resolution.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• Faster burst: Shoots at higher frequency (20 vs 11 flaps/sec) to capture the decisive moment.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Less heavy: Is lighter (by 49g or 16 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 15m).
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 11 years and 1 month of technical progress since the LX7 launch.

Reasons to prefer the Panasonic Lumix DMC-LX7:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.4 vs f/2.0).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in July 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the TG-7 is the clear winner of the match-up (13 : 7 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 OM System TG-7 and the Panasonic LX7 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 TG-7 and the LX7 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
