Sony A9 versus Canon 5D Mark IV
The Sony Alpha A9 and the Canon EOS 5D Mark IV are two professional cameras that were announced, respectively, in April 2017 and August 2016. The A9 is a mirrorless interchangeable lens camera, while the 5D Mark IV is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 24 megapixel, whereas the Canon provides 30.1 MP.
An illustration of the physical size and weight of the Sony A9 and the Canon 5D Mark IV is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 A9 – 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 5D Mark IV is considerably larger (136 percent) than the Sony A9. Moreover, the 5D Mark IV is markedly heavier (32 percent) than the A9. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A9) and the Canon EF Lens Catalog (5D Mark IV). Mirrorless cameras, such as the Sony A9, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
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. The 5D Mark IV was launched at a somewhat lower price (by 22 percent) than the A9, which makes it more attractive for photographers on a tight budget. 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 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 tent to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the 5D Mark IV is 2 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 30.1MP, the 5D Mark IV offers a higher resolution than the A9 (24MP), but the 5D Mark IV has smaller individual pixels (pixel pitch of 5.36μm versus 5.94μm for the A9). It is noteworthy in this context that the A9 is a somewhat more recent model (by 7 months) than the 5D Mark IV, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A9 has an electronic viewfinder (3686k dots), while the 5D Mark IV has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Sony A9 and Canon 5D Mark IV in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the A9 and the 5D Mark IV are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 5D Mark IV replaced the earlier Canon 5D Mark III, while the A9 does not have a direct predecessor.
So what conclusions can be drawn? Is the Sony A9 better than the Canon 5D Mark IV or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Sony Alpha A9:
- More framing info: Has an electronic viewfinder that displays shooting data.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (20 vs 7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (127x96mm vs 151x116mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 217g or 24 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 7 months after the 5D Mark IV).
Reasons to prefer the Canon EOS 5D Mark IV:
- More detail: Has more megapixels (30.1 vs 24MP), which boosts linear resolution by 12%.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1440k dots).
- Longer lasting: Gets more shots (900 versus 650) out of a single battery charge.
- More affordable: Was released into a lower priced segment (22 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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.
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 handling experience and imaging performance when actually working with the A9 or the 5D Mark IV. 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
