Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX7 and the Leica T (Typ 701)? 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 Panasonic GX7 and the Leica T 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.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica T is notably larger (6 percent) than the Panasonic GX7. However, the T Typ 701 is slightly lighter (4 percent) than the GX7. In this context, it is worth noting that neither the GX7 nor the T Typ 701 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GX7 gets 350 shots out of its Panasonic DMW-BLG10 battery, while the T Typ 701 can take 400 images on a single charge of its Leica BP-DC13 power pack. The power pack in the T Typ 701 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. 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 GX7 was launched at a markedly lower price (by 46 percent) than the T Typ 701, which puts it into a different market segment. 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 size of the sensor inside a digital camera is one of the key determinants 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 Panasonic GX7 features a Four Thirds sensor and the Leica T an APS-C sensor. The sensor area in the T Typ 701 is 65 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 GX7 has a native 4:3 aspect ratio, while the one in the T Typ 701 offers a 3:2 aspect.

With 16.2MP, the T Typ 701 offers a higher resolution than the GX7 (15.8MP), but the T Typ 701 nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 3.77μm for the GX7) due to its larger sensor. Moreover, the T Typ 701 is a somewhat more recent model (by 8 months) than the GX7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the T Typ 701 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Panasonic Lumix DMC-GX7 has a native sensitivity range from ISO 125 to ISO 25600. The corresponding ISO settings for the Leica T (Typ 701) are ISO 100 to ISO 12500 (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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the T Typ 701 has a markedly higher DXO score than the GX7 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.5 EV in additional dynamic range, and 0.6 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 GX7 provides a higher frame rate than the T Typ 701. It can shoot video footage at 1080/60p, while the Leica is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the T Typ 701 relies on live view and the rear LCD for framing. That said, the T Typ 701 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The table below summarizes some of the other core capabilities of the Panasonic GX7 and Leica T in connection with corresponding information for a sample of similar cameras.

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

One feature that differentiates the GX7 and the T Typ 701 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the T Typ 701 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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 GX7 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 Panasonic GX7 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 GX7 and the T Typ 701 write their files to SDXC cards. The GX7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T Typ 701 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-GX7 and Leica T (Typ 701) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GX7 and the T Typ 701 have been discontinued, but can regularly be found used on ebay. The GX7 was replaced by the Panasonic GX85, while the T Typ 701 was followed by the Leica TL. Further information on the features and operation of the GX7 and T Typ 701 can be found, respectively, in the Panasonic GX7 Manual (free pdf) or the online Leica T Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Panasonic GX7 and the Leica T? 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-GX7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2013).

Reasons to prefer the Leica T (Typ 701):

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
• Larger screen: Has a bigger rear LCD (3.7" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
• Longer lasting: Gets more shots (400 versus 350) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Was introduced somewhat (8 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the GX7 emerges as the winner of the contest (12 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 GX7 and the Leica T 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX7 or the T Typ 701. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
