Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm FinePix X100 and the Sony Alpha NEX-3N? 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

The physical size and weight of the Fujifilm X100 and the Sony NEX-3N 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 measures are rounded to the nearest millimeter.

The NEX-3N can be obtained in two different colors (black, white), while the X100 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 Sony NEX-3N is notably smaller (28 percent) than the Fujifilm X100. In this context, it is worth noting that neither the X100 nor the NEX-3N are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100 has a lens built in, whereas the NEX-3N 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 NEX-3N and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the X100 gets 300 shots out of its Fujifilm NP-95 battery, while the NEX-3N can take 480 images on a single charge of its Sony NP-FW50 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. 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 an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-3N is 2 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.

Despite having a slightly smaller sensor, the NEX-3N offers a higher resolution of 16 megapixels, compared with 12.2 MP of the X100. 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 4.78μm versus 5.53μm for the X100). However, it should be noted that the NEX-3N is much more recent (by 2 years and 5 months) than the X100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Sony NEX-3N implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3N for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Fujifilm X100 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Fujifilm FinePix X100 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Sony Alpha NEX-3N are ISO 200 to ISO 16000 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 NEX-3N provides a better video resolution than the X100. It can shoot movie footage at 1080/60i, while the Fujifilm is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X100 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-3N relies on live view and the rear LCD for framing. That said, the NEX-3N can be equipped with an optional viewfinder – the FDA-SV1. The following table reports on some other key feature differences and similarities of the Fujifilm X100, the Sony NEX-3N, and comparable cameras.

The X100 writes its imaging data to SDXC cards, while the NEX-3N uses SDXC or Memory Stick PRO Duo cards.

Connectivity comparison

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 FinePix X100 and Sony Alpha NEX-3N and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X100 has a hotshoe, while the NEX-3N does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the X100 and the NEX-3N have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the NEX-3N was followed by the Sony A5000. Further information on the features and operation of the X100 and NEX-3N can be found, respectively, in the Fujifilm X100 Manual (free pdf) or the online Sony NEX-3N Manual.

Review summary

So what is the bottom line? Is the Fujifilm X100 better than the Sony NEX-3N or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Fujifilm FinePix X100:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the NEX-3N requires a separate lens.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in September 2010).

Reasons to prefer the Sony Alpha NEX-3N:

• More detail: Has more megapixels (16 vs 12.2MP), which boosts linear resolution by 15%.
• Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• 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.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (110x62mm vs 126x75mm) and will fit more readily into a bag.
• Longer lasting: Gets more shots (480 versus 300) out of a single battery charge.
• More modern: Reflects 2 years and 5 months of technical progress since the X100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3N is the clear winner of the contest (9 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 X100 and the Sony NEX-3N place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the X100 and the NEX-3N in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
