Fujifilm X-A1 vs X100
The Fujifilm X-A1 and the Fujifilm FinePix X100 are two digital cameras that were officially introduced, respectively, in September 2013 and September 2010. The X-A1 is a mirrorless interchangeable lens camera, while the X100 is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The X-A1 has a resolution of 16 megapixels, whereas the X100 provides 12.2 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-A1 and the Fujifilm FinePix X100? 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 side-by-side display below illustrates the physical size and weight of the Fujifilm X-A1 and the Fujifilm X100. 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 X-A1 can be obtained in two different colors (black, blue), 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 X100 is notably larger (21 percent) than the Fujifilm X-A1. In this context, it is worth noting that neither the X-A1 nor the X100 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 X-A1 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 X-A1 and their specifications in the Fujinon X Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.
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 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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X100 is 1 percent bigger. 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.
In terms of chip-set technology, the X-A1 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.
Despite having a slightly smaller sensor, the Fujifilm X-A1 offers a higher resolution of 16 megapixels, compared with 12.2 MP of the Fujifilm 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 4.80μm versus 5.53μm for the X100). However, it should be noted that the X-A1 is much more recent (by 2 years and 11 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 Fujifilm X-A1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A1 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 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 X-A1 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 Fujifilm FinePix X100 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the X-A1 provides a higher video resolution than the X100. It can shoot video footage at 1080/30p, while the X100 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety 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 X-A1 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-A1, the Fujifilm X100, and comparable cameras.

The X-A1 writes its imaging data to SDHC cards, while the X100 uses SDXC cards. The X-A1 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.
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-A1 and Fujifilm FinePix X100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-A1 offers wifi support, while the X100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-A1 and the X100 have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the X-A1 was followed by the Fujifilm X-A2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm website.
So how do things add up? Which of the two cameras – the Fujifilm X-A1 or the Fujifilm X100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Fujifilm X-A1:
- More detail: Offers more megapixels (16 vs 12.2MP) with a 14% higher linear resolution.
- Better jpgs: Has a more modern image processing engine (EXR Processor II vs EXR Processor).
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k 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 (5.6 vs 5 flaps/sec) to capture the decisive moment.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (117x67mm vs 126x75mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (350 versus 300) on a single battery charge.
- 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 modern: Reflects 2 years and 11 months of technical progress since the X100 launch.
Arguments in favor of the Fujifilm FinePix X100:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Ready to shoot: Has an integrated lens, whereas the X-A1 necessitates an extra lens.
- More heavily discounted: Has been around for much longer (launched in September 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the X-A1 is the clear winner of the match-up (14 : 3 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 X-A1 and the Fujifilm X100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the X-A1 and the X100 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.
This is where reviews by experts come in. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
