Canon 5D Mark II versus Canon G9 X Mark II

The Canon EOS 5D Mark II and the Canon PowerShot G9 X Mark II are two digital cameras that were officially introduced, respectively, in September 2008 and January 2017. The 5D Mark II is a DSLR, while the G9X Mark II is a fixed lens compact. The cameras are based on a full frame (5D Mark II) and an one-inch (G9X Mark II) sensor. The 5D Mark II has a resolution of 21 megapixel, whereas the G9X Mark II provides 20 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 5D Mark II vs Canon G9 X Mark II

The physical size and weight of the Canon 5D Mark II and the Canon G9 X Mark II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 5D Mark II – represents 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 G9 X Mark II is considerably smaller (67 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 G9X Mark II does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens build 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 find an overview of optics for the 5D Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 5D Mark II gets 850 shots out of its LP-E6 battery, while the G9X Mark II can take 235 images on a single charge of its NB-13L power pack.

Any camera purchase will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G9X Mark II was launched at a lower price than the 5D Mark II, despite having a lens build 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.

 

Sensor comparison: Canon 5D Mark II vs Canon G9 X Mark II

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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 G9 X Mark II an one-inch sensor. The sensor area in the G9X Mark II is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 5D Mark II and Canon G9 X Mark II sensor measures

With 21MP, the 5D Mark II offers a slightly higher resolution than the G9X Mark II (20MP), but the 5D Mark II nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 2.41μm for the G9X Mark II) due to its larger sensor. However, the G9X Mark II is a somewhat more recent model (by 8 years and 3 months) than the 5D Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

5D Mark II versus G9X Mark II 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 5D Mark II provides substantially higher image quality than the G9X Mark II, with an overall score that is 14 points higher. This advantage is based on 1.8 bits higher color depth, 0.6 EV of lower dynamic range, and 1.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G9X Mark II provides a faster frame rate than the 5D Mark II. It can shoot movie footage at 1080/60p, while the 5D Mark II is limited to 1080/30p.

 

Feature comparison: Canon 5D Mark II vs Canon G9 X Mark II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 5D Mark II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 5D Mark II and Canon G9 X Mark II along with similar information for a selection of comparators.

The G9X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 5D Mark II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 5D Mark II was succeeded by the Canon 5D Mark III.

Review summary: Canon 5D Mark II vs Canon G9 X Mark II

So how do things add up? Which of the two cameras – the Canon 5D Mark II or the Canon G9 X Mark II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS 5D Mark II:

  • Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.8 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.8 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (850 versus 235) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in September 2008).


Arguments in favor of the Canon PowerShot G9 X Mark II:

  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (8.2 vs 3.9 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 5D Mark II requires a separate lens.
  • More compact: Is smaller (98x58mm vs 152x114mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 5D Mark II).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 8 years and 3 months of technical progress since the 5D Mark II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G9X Mark II emerges as the winner of the match-up (12 : 10 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.

5D Mark II 10:12 G9X Mark II

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 5D Mark II or the G9X Mark II handle or perform in practice. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 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.
