Leica T vs Panasonic GX850
The Leica T (Typ 701) and the Panasonic Lumix DMC-GX850 (labelled Panasonic GX800 in some countries) are two digital cameras that were officially introduced, respectively, in April 2014 and January 2017. Both the T Typ 701 and the GX850 are mirrorless interchangeable lens cameras that are based on an APS-C (T Typ 701) and a Four Thirds (GX850) sensor. The Leica has a resolution of 16.2 megapixels, whereas the Panasonic provides 15.8 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 Leica T (Typ 701) and the Panasonic Lumix DMC-GX850? 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.
The side-by-side display below illustrates the physical size and weight of the Leica T and the Panasonic GX850. 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 T Typ 701 can be obtained in two different colors (black, silver), while the GX850 is available in three color-versions (black, silver, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX850 is notably smaller (25 percent) than the Leica T. Moreover, the GX850 is markedly lighter (30 percent) than the T Typ 701. In this context, it is worth noting that neither the T Typ 701 nor the GX850 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.
The power pack in the T Typ 701 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. 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. The GX850 was launched at a markedly lower price (by 70 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.
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. 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 Leica T features an APS-C sensor and the Panasonic GX850 a Four Thirds sensor. The sensor area in the GX850 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the T Typ 701 has a native 3:2 aspect ratio, while the one in the GX850 offers a 4:3 aspect.
With 16.2MP, the T Typ 701 offers a slightly higher resolution than the GX850 (15.8MP), but the T Typ 701 nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 3.77μm for the GX850) due to its larger sensor. However, the GX850 is a much more recent model (by 2 years and 8 months) than the T Typ 701, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The Leica T (Typ 701) has a native sensitivity range from ISO 100 to ISO 12500. The corresponding ISO settings for the Panasonic Lumix DMC-GX850 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 GX850 provides a better video resolution than the T Typ 701. It can shoot movie footage at 4K/30p, while the Leica is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The T Typ 701 and the GX850 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 T Typ 701 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Leica T and Panasonic GX850 along with similar information for a selection of comparators.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
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 GX850 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 GX850 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 T Typ 701 and the GX850 write their files to SDXC cards. The GX850 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.
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 Leica T (Typ 701) and Panasonic Lumix DMC-GX850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T Typ 701 has a hotshoe, while the GX850 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The GX850 is a recent model that features in the current product line-up of Panasonic. In contrast, the T Typ 701 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the T Typ 701 was succeeded by the Leica TL. Further information on the features and operation of the T Typ 701 and GX850 can be found, respectively, in the Leica T Manual (free pdf) or the online Panasonic GX850 Manual.
So what conclusions can be drawn? Is there a clear favorite between the Leica T and the Panasonic GX850? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Leica T (Typ 701):
- Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- 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).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (400 versus 210) on a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More heavily discounted: Has been available for much longer (launched in April 2014).
Arguments in favor of the Panasonic Lumix DMC-GX850:
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (107x65mm vs 134x69mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 115g or 30 percent) and is thus easier to take along.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
- More modern: Reflects 2 years and 8 months of technical progress since the T Typ 701 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the GX850 emerges as the winner of the match-up (12 : 10 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 Leica T and the Panasonic GX850 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T Typ 701 or the GX850. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. 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 ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
