Canon 450D versus Canon G1 X

The Canon EOS 450D (called Canon XSi in some regions) and the Canon PowerShot G1 X are two digital cameras that were revealed to the public, respectively, in January 2008 and January 2012. The 450D is a DSLR, while the G1X is a fixed lens compact. The cameras are based on an APS-C (450D) and an 1.5-inch (G1X) sensor. The 450D has a resolution of 12.2 megapixel, whereas the G1X provides 14.2 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 450D vs Canon G1 X

The physical size and weight of the Canon 450D and the Canon G1 X are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 450D – represents the basis or 100 percent 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 Canon G1 X is notably smaller (25 percent) than the Canon 450D. In this context, it is worth noting that neither the 450D nor the G1X are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens build 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 find an overview of optics 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 G1X can take 250 images on a single charge of its NB-10L 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. 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 450D vs Canon G1 X

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. 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 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 G1 X an 1.5-inch sensor. The sensor area in the G1X is 20 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.85. The sensor in the 450D has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.

Canon 450D and Canon G1 X sensor measures

Despite having a smaller sensor, the G1X offers a higher resolution of 14.2 megapixel, compared with 12.2 MP of the 450D. 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 4.30μm versus 5.19μm for the 450D). However, it should be noted that the G1X is much more recent (by 3 years and 11 months) than the 450D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

450D versus G1X MP

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 cannot only take still pictures, but also record videos. The G1X indeed provides for movie recording, while the 450D does not. The highest resolution format that the G1X can use is 1080/24p.

 

Feature comparison: Canon 450D vs Canon G1 X

Apart from body and sensor, cameras can and do differ across a variety of features. The 450D and the G1X 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 G1 X, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the 450D and the G1X have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, while the G1X was followed by the Canon G1X Mark II.

Review summary: Canon 450D vs Canon G1 X

So what conclusions can be drawn? Which of the two cameras – the Canon 450D or the Canon G1 X – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 450D:

  • Faster burst: Shoots at higher frequency (3.5 vs 1.9 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 250) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in January 2008).


Reasons to prefer the Canon PowerShot G1 X:

  • More detail: Has more megapixels (14.2 vs 12.2MP), which boosts linear resolution by 6%.
  • Broader imaging potential: Can capture not only stills but also 1080/24p video.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • Ready to shoot: Comes with an integrated lens, while the 450D requires a separate lens.
  • More compact: Is smaller (117x81mm vs 129x98mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Reflects 3 years and 11 months of technical progress since the 450D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G1X emerges as the winner of the match-up (7 : 4 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.

450D 04:07 G1X

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 450D or the G1X handle or perform in practice. 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 where reviews by experts come in. 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
