Panasonic LX7 vs Sigma fp
The Panasonic Lumix DMC-LX7 and the Sigma fp are two digital cameras that were officially introduced, respectively, in July 2012 and July 2019. The LX7 is a fixed lens compact, while the fp is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (LX7) and a full frame (fp) sensor. The Panasonic has a resolution of 10 megapixels, whereas the Sigma provides 24 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-LX7 and the Sigma fp? 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 physical size and weight of the Panasonic LX7 and the Sigma fp 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.
The LX7 can be obtained in two different colors (black, white), while the fp is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sigma fp is somewhat larger (5 percent) than the Panasonic LX7. It is noteworthy in this context that the fp is splash and dust-proof, while the LX7 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 has a lens built in, whereas the fp is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The power pack in the fp 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. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX7 was launched at a lower price than the fp, 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 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. 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 Panasonic LX7 features a 1/1.7-inch sensor and the Sigma fp a full frame sensor. The sensor area in the fp is 1943 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.0. The sensor in the LX7 has a native 4:3 aspect ratio, while the one in the fp offers a 3:2 aspect. 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 24MP, the fp offers a higher resolution than the LX7 (10MP), but the fp nevertheless has larger individual pixels (pixel pitch of 5.98μm versus 2.05μm for the LX7) due to its larger sensor. Moreover, the fp is a much more recent model (by 6 years and 11 months) than the LX7, and its sensor will 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 fp has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sigma fp implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the fp for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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-LX7 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sigma fp are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 6-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the fp provides a better video resolution than the LX7. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The LX7 and the fp 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. However, optional viewfinders – the DMW-LVF2 for the LX7 and the EVF-11 for the fp – are available as accessories. The following table reports on some other key feature differences and similarities of the Panasonic LX7, the Sigma fp, and comparable cameras.
One difference between the cameras concerns the presence of an on-board flash. The LX7 has one, while the fp does not. While the built-in flash of the LX7 is not very powerful, it can at times be useful as a fill-in light.
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 fp 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 LX7 and the Sigma fp 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 LX7 and the fp write their files to SDXC cards. The fp supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the LX7 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 Panasonic Lumix DMC-LX7 and Sigma fp and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the fp has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The LX7 does not feature such a mic input.
The fp is a recent model that features in the current product line-up of Sigma. 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sigma websites.
So what is the bottom line? Is there a clear favorite between the Panasonic LX7 and the Sigma fp? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Panasonic Lumix DMC-LX7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the count of relative strengths (bullet points above) is taken as a measure, the fp is the clear winner of the contest (19 : 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the LX7 or the fp. 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], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
