Canon 40D vs G16

The Canon EOS 40D and the Canon PowerShot G16 are two digital cameras that were revealed to the public, respectively, in August 2007 and August 2013. The 40D is a DSLR, while the G16 is a fixed lens compact. The cameras are based on an APS-C (40D) and a 1/1.7-inch (G16) sensor. The 40D has a resolution of 10.1 megapixels, whereas the G16 provides 12 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 40D vs G16

An illustration of the physical size and weight of the Canon 40D and the Canon G16 is provided 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 measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G16 is considerably smaller (47 percent) than the Canon 40D. In this context, it is worth noting that neither the 40D nor the G16 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 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.

Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the G16 can take 360 images on a single charge of its NB-10L power pack.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G16 was launched at a lower price than the 40D, despite having a lens built 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 G16

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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 Canon G16 a 1/1.7-inch sensor. The sensor area in the G16 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.65. The sensor in the 40D has a native 3:2 aspect ratio, while the one in the G16 offers a 4:3 aspect.

Technology-wise, the G16 uses a more advanced image processing engine (DIGIC 6) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 40D and Canon G16 sensor measures

Despite having a smaller sensor, the G16 offers a higher resolution of 12 megapixels, compared with 10.1 MP of the 40D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.87μm versus 5.73μm for the 40D). However, it should be noted that the G16 is much more recent (by 6 years) than the 40D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

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 Canon PowerShot G16 are ISO 80 to ISO 12800 (no boost).

40D versus G16 MP

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. Of the two cameras under review, the 40D has a notably higher overall DXO score than the G16 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.4 EV of lower dynamic range, and 1.6 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 are not only capable of taking still images, but can also record movies. The G16 indeed provides for movie recording, while the 40D does not. The highest resolution format that the G16 can use is 1080/60p.

 

Feature comparison: Canon 40D vs G16

Apart from body and sensor, cameras can and do differ across a range of features. The 40D and the G16 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The table below summarizes some of the other core capabilities of the Canon 40D and Canon G16 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 40D, but is missing on the G16 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 G16 uses SDXC cards.

 

Connectivity comparison: Canon 40D vs G16

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 Canon PowerShot G16 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 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 offer wifi capability.

Studio photographers will appreciate that the Canon 40D (unlike the G16) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The G16 is a recent model that features in the current product line-up of Canon. 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 G16

So what is the bottom line? Which of the two cameras – the Canon 40D or the Canon G16 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS 40D:

  • Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6.5 vs 2.2 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (750 versus 360) 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).


Advantages of the Canon PowerShot G16:

  • More detail: Has more megapixels (12 vs 10.1MP), which boosts linear resolution by 7%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 3).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • Ready to shoot: Comes with an integrated lens, while the 40D requires a separate lens.
  • More compact: Is smaller (109x76mm 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).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 6 years of technical progress since the 40D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G16 comes out slightly ahead of the 40D (11 : 10 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.

40D 10:11 G16

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 40D and the G16 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.

Expert reviews: Canon 40D vs G16

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, please note that some of the review sites have changed their methodology and reporting over time.
