Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm FinePix X100 and the Sony Alpha SLT-A99? 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 side-by-side display below illustrates the physical size and weight of the Fujifilm X100 and the Sony A99. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

Size Fujifilm X100 vs Sony A99
Compare X100 versus A99 top
Comparison X100 or A99 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A99 is considerably larger (73 percent) than the Fujifilm X100. It is noteworthy in this context that the A99 is splash and dust-proof, while the X100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100 has a lens built in, whereas the A99 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the X100 gets 300 shots out of its NP-95 battery, while the A99 can take 500 images on a single charge of its NP-FM500H power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 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 X100 was launched at a lower price than the A99, despite having a lens built in. 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.

 

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X100 features an APS-C sensor and the Sony A99 a full frame sensor. The sensor area in the A99 is 128 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Fujifilm X100 and Sony A99 sensor measures

With 24MP, the A99 offers a higher resolution than the X100 (12.2MP), but the A99 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 5.53μm for the X100) due to its larger sensor. Moreover, the A99 is a somewhat more recent model (by 1 year and 11 months) than the X100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Fujifilm X100 are 21.4 x 14.2 inch or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inch or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inch 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 SLT-A99 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

X100 versus A99 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the A99 offers substantially better image quality than the X100 (overall score 16 points higher). The advantage is based on 2.1 bits higher color depth, 1.6 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A99 provides a better video resolution than the X100. It can shoot movie footage at 1080/60p, while the Fujifilm is limited to 720/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A99 offers a substantially higher resolution than the one in the X100 (2359k vs 1440k dots).

One difference between the cameras concerns the presence of an on-board flash. The X100 has one, while the A99 does not. While the built-in flash of the X100 is not very powerful, it can at times be useful as a fill-in light.

The A99 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the X100 does not have a selfie-screen.

The X100 writes its imaging data to SDXC cards, while the A99 uses SDXC or Memory Stick PRO Duo cards. The A99 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X100 cannot take advantage of Ultra High Speed SD 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 SLT-A99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A99 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X100 does not feature such a mic input.

Studio photographers will appreciate that the Sony A99 (unlike the X100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the A99 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the X100 and the A99 have been discontinued, but can regularly be found used on eBay. The X100 was replaced by the Fujifilm X100S, while the A99 was followed by the Sony A99 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Sony websites.


Review summary

So how do things add up? Is the Fujifilm X100 better than the Sony A99 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Fujifilm FinePix X100:

  • Ready to shoot: Comes with a built-in lens, while the A99 requires a separate lens.
  • More compact: Is smaller (126x75mm vs 147x111mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the A99).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in September 2010).

ilogo

Reasons to prefer the Sony Alpha SLT-A99:

  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (500 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A99 is the clear winner of the contest (25 : 6 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 A99 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 X100 or the A99. 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

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
