Canon 450D versus Canon G1 X Mark II

The Canon EOS 450D (called Canon XSi in some regions) and the Canon PowerShot G1 X Mark II are two digital cameras that were officially introduced, respectively, in January 2008 and February 2014. The 450D is a DSLR, while the G1X Mark II is a fixed lens compact. The cameras are based on an APS-C (450D) and an 1.5-inch sensor. The 450D has a resolution of 12.2 megapixel, whereas the G1X Mark II provides 13 MP.

Body comparison

The physical size and weight of the Canon 450D and the Canon G1 X Mark II are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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 side – the 450D – 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 Canon G1 X Mark II is considerably smaller (62 percent) than the Canon 450D. In this context, it is worth noting that neither the 450D nor the G1X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II 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.

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 comparisons there.

The listed 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

The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 450D features an APS-C sensor and the Canon G1 X Mark II an 1.5-inch sensor. The sensor area in the G1X Mark II 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 Mark II offers a 4:3 aspect.

Sensor size

Despite having a smaller sensor, the G1X Mark II offers a slightly higher resolution of 13 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 4.49μm versus 5.19μm for the 450D). However, it should be noted that the G1X Mark II is much more recent (by 6 years) than the 450D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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"). 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 Mark II indeed provides for movie recording, while the 450D does not. The highest resolution format that the G1X Mark II can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 450D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 450D and Canon G1 X Mark II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The G1X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 450D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 450D was succeeded by the Canon 500D.

Summary

So what is the bottom line? Is there a clear favorite between the Canon 450D and the Canon 450D? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 450D:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (500 versus 240) 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 Mark II:

  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (5.2 vs 3.5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 450D requires a separate lens.
  • More compact: Is smaller (116x74mm vs 129x98mm) and will fit more readily into a bag.
  • More modern: Reflects 6 years of technical progress since the 450D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark II is the clear winner of the contest (8 : 4 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 450D or the G1X Mark II. 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 table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
