Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 300D and the Canon PowerShot G1 X Mark II? 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

An illustration of the physical size and weight of the Canon 300D and the Canon G1 X Mark II is provided 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 size dimensions 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 G1 X Mark II is considerably smaller (39 percent) than the Canon 300D. In this context, it is worth noting that neither the 300D 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 built in, whereas the 300D 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 300D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 300D gets 400 shots out of its Canon BP-511 battery, while the G1X Mark II can take 240 images on a single charge of its Canon NB-12L power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras 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. The G1X Mark II was launched at a lower price than the 300D, 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. 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. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 300D 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 24 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 300D has a native 3:2 aspect ratio, while the one in the G1X Mark II offers a 4:3 aspect.

Technology-wise, the G1X Mark II uses a more advanced image processing engine (DIGIC 6) than the 300D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the G1X Mark II offers a higher resolution of 13 megapixels, compared with 6.3 MP of the 300D. 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 4.49μm versus 7.38μm for the 300D). However, it should be noted that the G1X Mark II is much more recent (by 10 years and 5 months) than the 300D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G1 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark II for good quality output (200 dots per inch) amounts to 20.8 x 15.6 inches or 52.8 x 39.6 cm, for very good quality (250 dpi) 16.6 x 12.5 inches or 42.3 x 31.7 cm, and for excellent quality (300 dpi) 13.9 x 10.4 inches or 35.2 x 26.4 cm. The corresponding values for the Canon 300D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.

The Canon EOS 300D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G1 X Mark II are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many 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 imaging performance. 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 300D does not. The highest resolution format that the G1X Mark II can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 300D 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. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon 300D and Canon G1 X Mark II along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark II has a touchscreen, while the 300D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G1 X Mark II 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 300D writes its imaging data to Compact Flash cards, while the G1X Mark II uses SDXC 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 300D and Canon PowerShot G1 X Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 300D does not provide wifi capability.

Both the 300D and the G1X Mark II have been discontinued, but can regularly be found used on ebay. The 300D was replaced by the Canon 350D, while the G1X Mark II was followed by the Canon G1 X Mark III. Further information on the features and operation of the 300D and G1X Mark II can be found, respectively, in the Canon 300D Manual (free pdf) or the online Canon G1 X Mark II Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon 300D or the Canon G1 X Mark II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS 300D:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (400 versus 240) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in August 2003).

Advantages of the Canon PowerShot G1 X Mark II:

• More detail: Has more megapixels (13 vs 6.3MP), which boosts linear resolution by 41%.
• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 118k 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.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5.2 vs 2.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the 300D requires a separate lens.
• More compact: Is smaller (116x74mm vs 142x99mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 300D).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• Easier file upload: Has wifi built 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 built-in lens.
• More modern: Reflects 10 years and 5 months of technical progress since the 300D 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 (19 : 4 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon 300D and the Canon G1 X Mark II 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 300D and the G1X Mark II 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.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
