Canon 40D vs Fujifilm X100S
The Canon EOS 40D and the Fujifilm X100S are two enthusiast cameras that were officially introduced, respectively, in August 2007 and January 2013. The 40D is a DSLR, while the X100S is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Fujifilm provides 16 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 Canon EOS 40D and the Fujifilm X100S? 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 Canon 40D and the Fujifilm X100S. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The X100S can be obtained in two different colors (black, silver), while the 40D 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 X100S is considerably smaller (40 percent) than the Canon 40D. In this context, it is worth noting that neither the 40D nor the X100S are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100S has a lens built in, whereas the 40D 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 40D and their specifications in the Canon EF Lens Catalog.
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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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. 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.
The size of the sensor inside a digital camera is one of the key determinants 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 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 X100S is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (40D) and 1.5. 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.
With 16MP, the X100S offers a higher resolution than the 40D (10.1MP), but the X100S has smaller individual pixels (pixel pitch of 4.80μm versus 5.73μm for the 40D). Yet, the X100S is a much more recent model (by 5 years and 4 months) than the 40D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X100S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X100S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X100S 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 Canon 40D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The X100S has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Fujifilm X100S are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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 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 are not only capable of taking still images, but can also record movies. The X100S indeed provides for movie recording, while the 40D does not. The highest resolution format that the X100S can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X100S has an electronic viewfinder (2360k dots), while the 40D 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 viewfinder in the X100S offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 40D has a higher magnification (0.59x vs 0.43x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 40D and Fujifilm X100S along with similar information for a selection of comparators.

One feature that is present on the 40D, but is missing on the X100S is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The 40D writes its imaging data to Compact Flash cards, while the X100S uses SDXC 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 Canon EOS 40D and Fujifilm X100S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 40D (unlike the X100S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 40D and the X100S have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the X100S was followed by the Fujifilm X100T. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Fujifilm websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon 40D and the Fujifilm X100S? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 40D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.43x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (750 versus 330) on a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in August 2007).
Arguments in favor of the Fujifilm X100S:
- More detail: Has more megapixels (16 vs 10.1MP), which boosts linear resolution by 26%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- Ready to shoot: Comes with an integrated lens, while the 40D requires a separate lens.
- More compact: Is smaller (127x74mm vs 146x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 40D).
- More modern: Reflects 5 years and 4 months of technical progress since the 40D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the X100S comes out slightly ahead of the 40D (11 : 10 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 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 Canon 40D and the Fujifilm X100S place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the X100S. 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.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
