Canon 40D vs Fujifilm X-A2
The Canon EOS 40D and the Fujifilm X-A2 are two digital cameras that were announced, respectively, in August 2007 and January 2015. The 40D is a DSLR, while the X-A2 is a mirrorless interchangeable lens camera. 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 X-A2? 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 physical size and weight of the Canon 40D and the Fujifilm X-A2 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 dimensions are rounded to the nearest millimeter.
The X-A2 can be obtained in three different colors (black, brown, white), 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 X-A2 is considerably smaller (50 percent) than the Canon 40D. Moreover, the X-A2 is substantially lighter (57 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the X-A2 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (40D) and the Fujinon X Lens Catalog (X-A2). Mirrorless cameras, such as the X-A2, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Any camera decision will obviously take relative prices into account. 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 X-A2 was launched at a markedly lower price (by 69 percent) than the 40D, which puts it into a different market segment. 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 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. 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 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 X-A2 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16MP, the X-A2 offers a higher resolution than the 40D (10.1MP), but the X-A2 has smaller individual pixels (pixel pitch of 4.80μm versus 5.73μm for the 40D). Yet, the X-A2 is a much more recent model (by 7 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.
The resolution advantage of the Fujifilm X-A2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A2 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 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 X-A2 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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"). 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 can also record movies. The X-A2 indeed provides for movie recording, while the 40D does not. The highest resolution format that the X-A2 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A2 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon 40D, the Fujifilm X-A2, and comparable cameras.
One feature that is present on the 40D, but is missing on the X-A2 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 X-A2 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 40D does not have a selfie-screen.
The 40D writes its imaging data to Compact Flash cards, while the X-A2 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 X-A2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the X-A2 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 40D does not provide wifi capability.
Studio photographers will appreciate that the Canon 40D (unlike the X-A2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 40D and the X-A2 have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the X-A2 was followed by the Fujifilm X-A3. 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 is the bottom line? Is there a clear favorite between the Canon 40D and the Fujifilm X-A2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 40D:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 5.6 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 410) 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 X-A2:
- More detail: Has more megapixels (16 vs 10.1MP), which boosts linear resolution by 26%.
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k 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.
- More compact: Is smaller (117x67mm vs 146x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 472g or 57 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
- More modern: Reflects 7 years and 4 months of technical progress since the 40D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the X-A2 is the clear winner of the contest (11 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 X-A2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 40D and the X-A2 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
