Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X70 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.

Body comparison: Fujifilm X70 vs Nikon D3100

The physical size and weight of the Fujifilm X70 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 size dimensions are rounded to the nearest millimeter.

The X70 can be obtained in two different colors (black, silver), while the D3100 is also available in two color-versions, but different ones (black, red).

Compare X70 versus D3100 top
Comparison X70 or D3100 rear

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 (65 percent) than the Fujifilm X70. In this context, it is worth noting that neither the X70 nor the D3100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X70 has a lens built in, whereas the D3100 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 D3100 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the X70 gets 330 shots out of its NP-95 battery, while the D3100 can take 550 images on a single charge of its EN-EL14 power pack. The power pack in the X70 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

 

Sensor comparison: Fujifilm X70 vs Nikon D3100

The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to 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.

Fujifilm X70 and Nikon D3100 sensor measures

With 16MP, the X70 offers a higher resolution than the D3100 (14.2MP), but the X70 has smaller individual pixels (pixel pitch of 4.80μm versus 5.01μm for the D3100). However, the X70 is a much more recent model (by 5 years and 4 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 X70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X70 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inch or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inch or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inch or 41.5 x 27.6 cm. The corresponding values for the Nikon D3100 are 23 x 15.4 inch or 58.5 x 39 cm for good quality, 18.4 x 12.3 inch or 46.8 x 31.2 cm for very good quality, and 15.4 x 10.2 inch or 39 x 26 cm for excellent quality prints.

The X70 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X70 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-51200. 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.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X70 provides a higher frame rate than the D3100. It can shoot video footage at 1080/60p, while the Nikon is limited to 1080/24p.

 

Feature comparison: Fujifilm X70 vs Nikon D3100

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 X70 relies on live view and the rear LCD for framing. That said, the X70 can be equipped with an optional viewfinder – the VF-X21.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X70 has a touchscreen, while the D3100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The X70 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D3100 does not have a selfie-screen.

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 X70 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 X70 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 X70 and the D3100 write their files to SDXC cards. The X70 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.

 

Connectivity comparison: Fujifilm X70 vs Nikon D3100

ilogo

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 framing and settings control.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (550 versus 330) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in August 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the X70 is the clear winner of the match-up (18 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 X70 and the Nikon D3100 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 X70 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.

Expert reviews: Fujifilm X70 vs Nikon D3100

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
