Fujifilm X-M1 vs Panasonic GX1
The Fujifilm X-M1 and the Panasonic Lumix DMC-GX1 are two digital cameras that were officially introduced, respectively, in June 2013 and November 2011. Both the X-M1 and the GX1 are mirrorless interchangeable lens cameras that are based on an APS-C (X-M1) and a Four Thirds (GX1) sensor. The Fujifilm has a resolution of 16 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 Fujifilm X-M1 and the Panasonic Lumix DMC-GX1? 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 Fujifilm X-M1 and the Panasonic GX1. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The X-M1 can be obtained in three different colors (black, silver, brown), while the GX1 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 Fujifilm X-M1 and the Panasonic GX1 are of equal size. However, the GX1 is slightly lighter (4 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the GX1 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-M1) and the Micro Four Thirds Lens Catalog (GX1). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The two cameras under review were launched at the same price and fall into the same market segment. 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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-M1 features an APS-C sensor and the Panasonic GX1 a Four Thirds sensor. The sensor area in the GX1 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 X-M1 has a native 3:2 aspect ratio, while the one in the GX1 offers a 4:3 aspect.
With 16MP, the X-M1 offers a slightly higher resolution than the GX1 (15.8MP), but the X-M1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.77μm for the GX1) due to its larger sensor. Moreover, the X-M1 is a somewhat more recent model (by 1 year and 7 months) than the GX1, and its sensor might 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 the X-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Fujifilm X-M1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX1 are ISO 160 to ISO 12800 (no boost).
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 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX1 provides a faster frame rate than the X-M1. It can shoot movie footage at 1080/60p, while the Fujifilm is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The X-M1 and the GX1 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 GX1 can be equipped with an optional viewfinder – the DMW-LVF2. The adjacent table lists some of the other core features of the Fujifilm X-M1 and Panasonic GX1 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX1 has a touchscreen, while the X-M1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
Concerning the storage of imaging data, both the X-M1 and the GX1 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Fujifilm X-M1 and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the X-M1 offers wifi support, while the GX1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-M1 and the GX1 have been discontinued, but can regularly be found used on eBay. The GX1 was replaced by the Panasonic GX7, while the X-M1 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Panasonic websites.
So how do things add up? Which of the two cameras – the Fujifilm X-M1 or the Panasonic GX1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Fujifilm X-M1:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features a larger and more technologically advanced imaging 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 (920k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (5.6 vs 4.2 flaps/sec) to capture the decisive moment.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Is somewhat more recent (announced 1 year and 7 months after the GX1).
Advantages of the Panasonic Lumix DMC-GX1:
- 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).
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More heavily discounted: Has been on the market for longer (launched in November 2011).
If the number of relative strengths (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (10 : 5 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 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 X-M1 or the GX1. 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.
This is why expert reviews are important. 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.

Care should be taken when interpreting the review scores above, 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 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.
