Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-LX100 and the YI M1? 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 LX100 and the YI M1 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 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 YI M1 is somewhat smaller (4 percent) than the Panasonic LX100. In this context, it is worth noting that neither the LX100 nor the M1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens built in, whereas the M1 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 M1 and their specifications in the Micro Four Thirds Lens Catalog.

The power pack in the M1 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. 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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

Both cameras under consideration feature a Four Thirds sensor, but their sensors differ slightly in size. The sensor area in the M1 is 22 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 2.2 (LX100) and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX100 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 20.2MP, the M1 offers a higher resolution than the LX100 (12.7MP), but the M1 has smaller individual pixels (pixel pitch of 3.34μm versus 3.82μm for the LX100). Yet, the M1 is a much more recent model (by 2 years) than the LX100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the YI M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M1 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Panasonic LX100 are 20.6 x 15.4 inches or 52.2 x 39.2 cm for good quality, 16.4 x 12.4 inches or 41.8 x 31.4 cm for very good quality, and 13.7 x 10.3 inches or 34.8 x 26.1 cm for excellent quality prints.

The Panasonic Lumix DMC-LX100 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the YI M1 are ISO 100 to ISO 25600 (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 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the LX100 has an electronic viewfinder (2764k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic LX100, the YI M1, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M1 has a touchscreen, while the LX100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 LX100 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 LX100 and the YI M1 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.

Concerning the storage of imaging data, both the LX100 and the M1 write their files to SDXC cards. The LX100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M1 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-LX100 and YI M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the LX100 and the M1 have been discontinued, but can regularly be found used on ebay. The LX100 was replaced by the Panasonic LX100 II, while the M1 does not have a direct successor. Further information on the features and operation of the LX100 and M1 can be found, respectively, in the Panasonic LX100 Manual (free pdf) or the online YI M1 Manual.

Review summary

So how do things add up? Is the Panasonic LX100 better than the YI M1 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Panasonic Lumix DMC-LX100:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has a lens built-in, whereas the M1 requires a separate lens.
• 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 heavily discounted: Has been available for much longer (launched in September 2014).

Reasons to prefer the YI M1:

• More detail: Has more megapixels (20.2 vs 12.7MP), which boosts linear resolution by 26%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (450 versus 300) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 2 years of technical progress since the LX100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M1 emerges as the winner of the match-up (12 : 9 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 LX100 and the YI M1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the LX100 and the M1 in practical situations. 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.

Expert reviews

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], 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.

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

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.
