Canon 450D vs G16

The Canon EOS 450D (called Canon XSi in some regions) and the Canon PowerShot G16 are two digital cameras that were revealed to the public, respectively, in January 2008 and August 2013. The 450D is a DSLR, while the G16 is a fixed lens compact. The cameras are based on an APS-C (450D) and a 1/1.7-inch (G16) sensor. The 450D has a resolution of 12.2 megapixels, whereas the G16 provides 12 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 450D and the Canon PowerShot G16? 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.

Body comparison

The physical size and weight of the Canon 450D and the Canon G16 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Compare 450D versus G16 top
Comparison 450D or G16 rear

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 (34 percent) than the Canon 450D. In this context, it is worth noting that neither the 450D 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 450D 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 450D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its LP-E5 battery, while the G16 can take 360 images on a single charge of its NB-10L power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 G16 was launched at a lower price than the 450D, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 size of the imaging sensor is a crucial determinant 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 450D 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 450D 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 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 450D and Canon G16 sensor measures

With 12.2MP, the 450D offers a slightly higher resolution than the G16 (12MP), but the 450D nevertheless has larger individual pixels (pixel pitch of 5.19μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 5 years and 6 months) than the 450D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G16 are ISO 80 to ISO 12800 (no boost).

In terms of underlying technology, the 450D is build around a CMOS sensor, while the G16 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

450D versus G16 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 review, the 450D has a notably higher overall DXO score than the G16 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.9 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 also of capturing video footage. The G16 indeed provides for movie recording, while the 450D does not. The highest resolution format that the G16 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 450D 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 following table reports on some other key feature differences and similarities of the Canon 450D, the Canon G16, and comparable cameras.

The Canon G16 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The 450D writes its imaging data to SDHC cards, while the G16 uses SDXC cards. The G16 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 450D cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 450D 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 450D does not provide wifi capability.

Both the 450D and the G16 have been discontinued, but can regularly be found used on ebay. The 450D was replaced by the Canon 500D, while the G16 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So how do things add up? Which of the two cameras – the Canon 450D or the Canon G16 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 450D:

  • Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
  • Faster burst: Shoots at higher frequency (3.5 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 (500 versus 360) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in January 2008).


Reasons to prefer the Canon PowerShot G16:

  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • 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).
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the 450D requires a separate lens.
  • More compact: Is smaller (109x76mm vs 129x98mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 450D).
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 5 years and 6 months of technical progress since the 450D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G16 is the clear winner of the contest (13 : 6 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 before making a camera decision. 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.

450D 06:13 G16

How about other alternatives? Do the specifications of the Canon 450D and the Canon G16 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 450D or the G16. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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.
