Canon 40D versus Sony A6000

The Canon EOS 40D and the Sony Alpha A6000 are two enthusiast cameras that were revealed to the public, respectively, in August 2007 and February 2014. The 40D is a DSLR, while the A6000 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 Sony provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 40D vs Sony A6000

The side-by-side display below illustrates the physical size and weight of the Canon 40D and the Sony A6000. 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. You can also use the toggle button 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 Sony A6000 is considerably smaller (49 percent) than the Canon 40D. Moreover, the A6000 is substantially lighter (58 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the A6000 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 Sony E-Mount Lens Catalog (A6000). Mirrorless cameras, such as the A6000, 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.

Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the A6000 can take 360 images on a single charge of its NP-FW50 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A6000 was launched at a markedly lower price (by 54 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: Canon 40D vs Sony A6000

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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A6000 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.

Canon 40D and Sony A6000 sensor measures

With 24MP, the A6000 offers a higher resolution than the 40D (10.1MP), but the A6000 has smaller individual pixels (pixel pitch of 3.91μm versus 5.73μm for the 40D). Yet, the A6000 is a much more recent model (by 6 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.

40D versus A6000 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A6000 offers substantially better image quality than the 40D (overall score 18 points higher). The advantage is based on 2 bits higher color depth, 1.8 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. 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. The A6000 indeed provides for movie recording, while the 40D does not. The highest resolution format that the A6000 can use is 1080/60p.

 

Feature comparison: Canon 40D vs Sony A6000

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A6000 has an electronic viewfinder (1440k 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 following table reports on some other key feature differences and similarities of the Canon 40D, the Sony A6000, and comparable cameras.

Arguments in favor of the Sony Alpha A6000:

  • More detail: Has more megapixels (24 vs 10.1MP), which boosts linear resolution by 54%.
  • Better image quality: Scores substantially higher (18 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (11 vs 6.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 146x108mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 478g or 58 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 (54 percent cheaper at launch).
  • More modern: Reflects 6 years and 5 months of technical progress since the 40D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A6000 is the clear winner of the contest (15 : 5 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.

40D 05:15 A6000

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 40D or the A6000 handle or perform in practice. 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
