Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm FinePix X100 and the Fujifilm X20? 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

An illustration of the physical size and weight of the Fujifilm X100 and the Fujifilm X20 is provided 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 X20 can be obtained in two different colors (black, silver), 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 Fujifilm X20 is notably smaller (13 percent) than the Fujifilm X100. Moreover, the X20 is markedly lighter (21 percent) than the X100. In this context, it is worth noting that neither the X100 nor the X20 are weather-sealed.

Concerning battery life, the X100 gets 300 shots out of its Fujifilm NP-95 battery, while the X20 can take 270 images on a single charge of its Fujifilm NP-50 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. The X20 was launched at a markedly lower price (by 50 percent) than the X100, which puts it into a different market segment. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Of the two cameras under consideration, the Fujifilm X100 features an APS-C sensor and the Fujifilm X20 a 2/3 sensor. The sensor area in the X20 is 84 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 3.9. The sensor in the X100 has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.

Technology-wise, the X20 uses a more advanced image processing engine (EXR Processor II) than the X100 (EXR Processor), with benefits for noise reduction, color accuracy, and processing speed.

With 12.2MP, the X100 offers a slightly higher resolution than the X20 (12MP), but the X100 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 2.20μm for the X20) due to its larger sensor. However, the X20 is a much more recent model (by 2 years and 3 months) than the X100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The X20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 Fujifilm X20 are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the X100 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X20 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 X20 provides a better video resolution than the X100. It can shoot movie footage at 1080/60p, while the X100 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), while the X20 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image.

The X20 is equipped with a zoom lens, while the X100 comes with a built-in prime. The X20 has a 28-112mm f/2.0-2.8 optic and the X100 offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the X20 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the X100. Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the X100 and the X20 write their files to SDXC 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 Fujifilm X20 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X100 and the X20 have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the X20 was followed by the Fujifilm X30. Further information on the features and operation of the X100 and X20 can be found, respectively, in the Fujifilm X100 Manual (free pdf) or the online Fujifilm X20 Manual.

Review summary

So how do things add up? Which of the two cameras – the Fujifilm X100 or the Fujifilm X20 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Fujifilm FinePix X100:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Longer lasting: Can take more shots (300 versus 270) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in September 2010).

Arguments in favor of the Fujifilm X20:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (EXR Processor II vs EXR Processor).
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (117x70mm vs 126x75mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 92g or 21 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More modern: Reflects 2 years and 3 months of technical progress since the X100 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the X20 is the clear winner of the contest (12 : 8 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 Fujifilm X20 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the X100 and the X20 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 expert reviews 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
