Canon 40D versus Sony RX100 V

The Canon EOS 40D and the Sony Cyber-shot DSC-RX100 V are two digital cameras that were revealed to the public, respectively, in August 2007 and October 2016. The 40D is a DSLR, while the RX100 V is a fixed lens compact. The cameras are based on an APS-C (40D) and an one-inch (RX100 V) sensor. The Canon has a resolution of 10.1 megapixel, whereas the Sony provides 20 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 RX100 V

The physical size and weight of the Canon 40D and the Sony RX100 V 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 size 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 RX100 V is considerably smaller (62 percent) than the Canon 40D. In this context, it is worth noting that neither the 40D nor the RX100 V are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens build 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 find an overview of optics for the 40D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the RX100 V can take 220 images on a single charge of its NP-BX1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera purchase will naturally be influenced heavily by the price. 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. The RX100 V was launched at a lower price than the 40D, despite having a lens build in. 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.

 

Sensor comparison: Canon 40D vs Sony RX100 V

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 40D and Sony RX100 V sensor measures

Despite having a smaller sensor, the RX100 V offers a higher resolution of 20 megapixel, compared with 10.1 MP of the 40D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 5.73μm for the 40D). However, it should be noted that the RX100 V is much more recent (by 9 years and 1 month) than the 40D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

40D versus RX100 V MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under consideration, the RX100 V has a markedly higher DXO score than the 40D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 1.1 EV in additional dynamic range, 0.3 stops of reduced low light sensitivity. 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 RX100 V indeed provides for movie recording, while the 40D does not. The highest resolution format that the RX100 V can use is 4K/30p.

 

Feature comparison: Canon 40D vs Sony RX100 V

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX100 V has an electronic viewfinder (2359k 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 table below summarizes some of the other core capabilities of the Canon 40D and Sony RX100 V in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the 40D, but is missing on the RX100 V 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the RX100 V features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The 40D writes its imaging data to Compact Flash cards, while the RX100 V uses SDXC or Memory Stick PRO Duo cards.

The RX100 V is a recent model that features in the current product line-up of Sony. 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.

Review summary: Canon 40D vs Sony RX100 V

So what conclusions can be drawn? Is the Canon 40D better than the Sony RX100 V or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon EOS 40D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (750 versus 220) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

ilogo

Advantages of the Sony Cyber-shot DSC-RX100 V:

  • More detail: Has more megapixels (20 vs 10.1MP), which boosts linear resolution by 41%.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (24 vs 6.5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Ready to shoot: Comes with an integrated lens, while the 40D requires a separate lens.
  • More compact: Is smaller (102x58mm vs 146x108mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 40D).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 9 years and 1 month of technical progress since the 40D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 V is the clear winner of the contest (17 : 7 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 07:17 RX100 V

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 RX100 V 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
