Canon 5D Mark II vs G1X
The Canon EOS 5D Mark II and the Canon PowerShot G1 X are two digital cameras that were announced, respectively, in September 2008 and January 2012. The 5D Mark II is a DSLR, while the G1X is a fixed lens compact. The cameras are based on a full frame (5D Mark II) and an 1.5-inch (G1X) sensor. The 5D Mark II has a resolution of 21 megapixels, whereas the G1X provides 14.2 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 5D Mark II and the Canon PowerShot G1 X? 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.
An illustration of the physical size and weight of the Canon 5D Mark II and the Canon G1 X 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 is considerably smaller (45 percent) than the Canon 5D Mark II. It is worth mentioning in this context that the 5D Mark II is splash and dust resistant, while the G1X does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the 5D Mark II 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 5D Mark II and their specifications in the Canon EF Lens Catalog.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1X was launched at a lower price than the 5D Mark II, 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 5D Mark II features a full frame sensor and the Canon G1 X an 1.5-inch sensor. The sensor area in the G1X is 70 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.85. The sensor in the 5D Mark II has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.
Technology-wise, the G1X uses a more advanced image processing engine (DIGIC 5) than the 5D Mark II (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 21MP, the 5D Mark II offers a higher resolution than the G1X (14.2MP), but the 5D Mark II nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.30μm for the G1X) due to its larger sensor. However, the G1X is a much more recent model (by 3 years and 3 months) than the 5D Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 5D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark II for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Canon G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.
The Canon EOS 5D Mark II has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Canon PowerShot G1 X are ISO 100 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 5D Mark II provides substantially higher image quality than the G1X, with an overall score that is 19 points higher. This advantage is based on 2 bits higher color depth, 1.1 EV in additional dynamic range, and 1.5 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 5D Mark II provides a higher frame rate than the G1X. It can shoot video footage at 1080/30p, while the G1X is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The 5D Mark II 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 adjacent table lists some of the other core features of the Canon 5D Mark II and Canon G1 X along with similar information for a selection of comparators.

One feature that is present on the 5D Mark II, but is missing on the G1X 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 G1X has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 5D Mark II does not have a selfie-screen.
The 5D Mark II writes its imaging data to Compact Flash cards, while the G1X uses SDXC cards.
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 5D Mark II and Canon PowerShot G1 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark II has a microphone port, which is missing on the G1X. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Canon 5D Mark II (unlike the G1X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 5D Mark II and the G1X have been discontinued, but can regularly be found used on eBay. The 5D Mark II was replaced by the Canon 5D Mark III, while the G1X was followed by the Canon G1X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon 5D Mark II and the Canon G1 X? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 5D Mark II:
- More detail: Offers more megapixels (21 vs 14.2MP) with a 24% higher linear resolution.
- Better image quality: Scores substantially higher (19 points) in the DXO overall assessment.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark II is the clear winner of the match-up (15 : 9 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. 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 5D Mark II and the Canon G1 X 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 5D Mark II or the G1X. 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 provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
