Olympus E-P1 vs Panasonic LX100
The Olympus PEN E-P1 and the Panasonic Lumix DMC-LX100 are two enthusiast cameras that were revealed to the public, respectively, in June 2009 and September 2014. The E-P1 is a mirrorless interchangeable lens camera, while the LX100 is a fixed lens compact. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Panasonic provides 12.7 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 Olympus PEN E-P1 and the Panasonic Lumix DMC-LX100? 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 Olympus E-P1 and the Panasonic LX100 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 size dimensions are rounded to the nearest millimeter.
The E-P1 can be obtained in three different colors (black, silver, white), while the LX100 is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX100 is notably smaller (10 percent) than the Olympus E-P1. In this context, it is worth noting that neither the E-P1 nor the LX100 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 E-P1 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 E-P1 and their specifications in the Micro Four Thirds Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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. 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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.
Both cameras under consideration feature a Four Thirds sensor, but their sensors differ slightly in size. The sensor area in the LX100 is 18 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 2.0 (E-P1) and 2.2. 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.
Despite having a smaller sensor, the LX100 offers a slightly higher resolution of 12.7 megapixels, compared with 12.2 MP of the E-P1. 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 3.82μm versus 4.29μm for the E-P1). However, it should be noted that the LX100 is much more recent (by 5 years and 3 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-LX100 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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"). Of the two cameras under consideration, the LX100 offers substantially better image quality than the E-P1 (overall score 12 points higher). The advantage is based on 0.9 bits higher color depth, 2.1 EV in additional dynamic range, and -0 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LX100 provides a better video resolution than the E-P1. It can shoot movie footage at 4K/30p, while the Olympus is limited to 720/30p.
Beyond 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 E-P1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-P1 and Panasonic LX100 in connection with corresponding information for a sample of similar cameras.

|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 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 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.
The E-P1 writes its imaging data to SDHC cards, while the LX100 uses SDXC cards. The LX100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 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 Olympus PEN E-P1 and Panasonic Lumix DMC-LX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P1 does not provide wifi capability.
The LX100 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-P1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-P1 was succeeded by the Olympus E-P2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.
So how do things add up? Is the Olympus E-P1 better than the Panasonic LX100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Olympus PEN E-P1:
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More heavily discounted: Has been available for much longer (launched in June 2009).
Advantages of the Panasonic Lumix DMC-LX100:
- Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
- Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
- Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster burst: Shoots at higher frequency (11 vs 3 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.
- Ready to shoot: Has an integrated lens, whereas the E-P1 necessitates an extra lens.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- 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 modern: Reflects 5 years and 3 months of technical progress since the E-P1 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the LX100 is the clear winner of the contest (14 : 2 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 Olympus E-P1 and the Panasonic LX100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings 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 incomplete and does no justice, for example, to the way the E-P1 or the LX100 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews 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.

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. 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, please note that some of the review sites have changed their methodology and reporting over time.
