Fujifilm X-A10 vs Nikon D3100
The Fujifilm X-A10 and the Nikon D3100 are two digital cameras that were officially introduced, respectively, in December 2016 and August 2010. The X-A10 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-A10 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 physical size and weight of the Fujifilm X-A10 and the Nikon D3100 are illustrated in the side-by-side display below. 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 width, height and depth dimensions are rounded to the nearest millimeter.
The D3100 can be obtained in two different colors (black, red), while the X-A10 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 Nikon D3100 is considerably larger (52 percent) than the Fujifilm X-A10. Moreover, the D3100 is substantially heavier (53 percent) than the X-A10. In this context, it is worth noting that neither the X-A10 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-A10) and the Nikon Lens Catalog (D3100). Mirrorless cameras, such as the Fujifilm X-A10, 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.
Concerning battery life, the X-A10 gets 410 shots out of its NP-W126S battery, while the D3100 can take 550 images on a single charge of its EN-EL14 power pack. The power pack in the X-A10 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 X-A10 was launched at a markedly lower price (by 33 percent) than the D3100, which puts it into a different market segment. 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 size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies 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-A10 offers a higher resolution than the D3100 (14.2MP), but the X-A10 has smaller individual pixels (pixel pitch of 4.80μm versus 5.01μm for the D3100). However, the X-A10 is a much more recent model (by 6 years and 3 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.
The resolution advantage of the Fujifilm X-A10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A10 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-A10 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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, but the X-A10 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-A10 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A10, the Nikon D3100, and comparable cameras.

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 X-A10 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 Fujifilm X-A10 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.
Concerning the storage of imaging data, both the X-A10 and the D3100 write their files to SDXC cards. The X-A10 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-A10 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-A10 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-A10 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-A10 was followed by the Fujifilm X-A5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Nikon websites.
So how do things add up? Is the Fujifilm X-A10 better than the Nikon D3100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Fujifilm X-A10:
- More detail: Offers more megapixels (16 vs 14.2MP) with a 6% higher linear resolution.
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6 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.
- More compact: Is smaller (117x67mm vs 124x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 174g or 34 percent) and hence easier to carry around.
- Easier travel charging: Can be conveniently charged via its USB port.
- 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 affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More modern: Reflects 6 years and 3 months of technical progress since the D3100 launch.
Reasons to prefer the Nikon D3100:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Gets more shots (550 versus 410) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in August 2010).
If the count of relative strengths (bullet points above) is taken as a measure, the X-A10 is the clear winner of the match-up (16 : 4 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 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 Fujifilm X-A10 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X-A10 or the D3100. 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 hands-on reviews by experts 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
