Fujifilm X-M1 vs Nikon D3100
The Fujifilm X-M1 and the Nikon D3100 are two digital cameras that were announced, respectively, in June 2013 and August 2010. The X-M1 is a mirrorless interchangeable lens camera, while the D3100 is a DSLR. Both cameras are equipped with an APS-C sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Nikon provides 14.2 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 Nikon D3100? 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 Nikon D3100. 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 X-M1 can be obtained in three different colors (black, silver, brown), while the D3100 is available in two color-versions (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3100 is considerably larger (52 percent) than the Fujifilm X-M1. Moreover, the D3100 is substantially heavier (53 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the D3100 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-M1) and the Nikon Lens Catalog (D3100). Mirrorless cameras, such as the Fujifilm X-M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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. The D3100 was launched at a somewhat lower price (by 14 percent) than the X-M1, which makes it more attractive for photographers on a tight budget. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D3100 is 3 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 16MP, the X-M1 offers a higher resolution than the D3100 (14.2MP), but the X-M1 has smaller individual pixels (pixel pitch of 4.80μm versus 5.01μm for the D3100). However, the X-M1 is a much more recent model (by 2 years and 10 months) than the D3100, and its sensor will have benefitted from technological advances during this time that 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 resolution advantage of the Fujifilm X-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-M1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Nikon D3100 are 23 x 15.4 inches or 58.5 x 39 cm for good quality, 18.4 x 12.3 inches or 46.8 x 31.2 cm for very good quality, and 15.4 x 10.2 inches or 39 x 26 cm for excellent quality prints.
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 Nikon D3100 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-12800.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X-M1 uses Fujifilm's X-Trans layout of photosites, while the D3100 employs the more common Bayer array.
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.
|Note: DXO values in italics represent estimates based on sensor size and age.|
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 X-M1 provides a higher frame rate than the D3100. It can shoot video footage at 1080/30p, while the Nikon is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D3100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-M1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X-M1 and Nikon D3100 along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the X-M1 and the D3100 write their files to SDXC cards. The X-M1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3100 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 Fujifilm X-M1 and Nikon D3100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-M1 offers wifi support, while the D3100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-M1 and the D3100 have been discontinued, but can regularly be found used on ebay. The D3100 was replaced by the Nikon D3200, while the X-M1 does not have a direct successor. Further information on the features and operation of the X-M1 and D3100 can be found, respectively, in the Fujifilm X-M1 Manual (free pdf) or the online Nikon D3100 Manual.
So how do things add up? Which of the two cameras – the Fujifilm X-M1 or the Nikon D3100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Fujifilm X-M1:
- More detail: Offers more megapixels (16 vs 14.2MP) with a 6% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (5.6 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x67mm vs 124x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 175g or 35 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 10 months of technical progress since the D3100 launch.
Advantages of the Nikon D3100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Gets more shots (550 versus 350) out of a single battery charge.
- More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (12 : 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.
How about other alternatives? Do the specifications of the Fujifilm X-M1 and the Nikon D3100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X-M1 or the D3100. 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 review scores listed above should be treated 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.
