Canon 40D versus Fujifilm X-A5

The Canon EOS 40D and the Fujifilm X-A5 are two digital cameras that were announced, respectively, in August 2007 and January 2018. The 40D is a DSLR, while the X-A5 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixel, whereas the Fujifilm provides 24 MP.

Body comparison

An illustration of the physical size and weight of the Canon 40D and the Fujifilm X-A5 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 40D – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-A5 is notably smaller (50 percent) than the Canon 40D. Moreover, the X-A5 is substantially lighter (56 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the X-A5 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (40D) and the Fujinon X Lens Catalog (X-A5). Mirrorless cameras, such as the X-A5, 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.

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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-A5 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 tent 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-A5 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.

Sensor size

With 24MP, the X-A5 offers a higher resolution than the 40D (10.1MP), but the X-A5 has smaller individual pixels (pixel pitch of 3.92μm versus 5.73μm for the 40D). Yet, the X-A5 is a much more recent model (by 10 years and 5 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.

Many modern cameras cannot only take still pictures, but also record videos. The X-A5 indeed provides for movie recording, while the 40D does not. The highest resolution format that the X-A5 can use is 4K/15p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A5 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 40D and Fujifilm X-A5 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The X-A5 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 40D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D.

Summary

So how do things add up? Which of the two cameras – the Canon 40D or the Fujifilm X-A5 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of the Canon EOS 40D:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Can take more shots (750 versus 450) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

Arguments in favor of the Fujifilm X-A5:

  • More detail: Has more megapixels (24 vs 10.1MP), which boosts linear resolution by 54%.
  • Broader imaging potential: Can capture not only stills but also 4K/15p video.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (117x68mm vs 146x108mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 461g or 56 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
  • More modern: Reflects 10 years and 5 months of technical progress since the 40D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the X-A5 is the clear winner of the contest (10 : 5 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.

40D 05:10 X-A5

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 40D and the X-A5 in practical situations. 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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.
