Panasonic GH4 versus Canon 7D II

The Panasonic Lumix DMC-GH4 and the Canon EOS 7D Mark II are two enthusiast cameras that were officially introduced, respectively, in February 2014 and September 2014. The GH4 is a mirrorless interchangeable lens camera, while the 7D Mark II is a DSLR. The cameras are based on a Four Thirds (GH4) and an APS-C (7D Mark II) sensor. The Panasonic has a resolution of 15.9 megapixel, whereas the Canon 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: Panasonic GH4 vs Canon 7D II

An illustration of the physical size and weight of the Panasonic GH4 and the Canon 7D II is provided in the side-by-side display below. Three successive views from the front, the top, and the rear 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 GH4 – 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 7D II is notably larger (35 percent) than the Panasonic GH4. Moreover, the 7D Mark II is substantially heavier (63 percent) than the GH4. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (GH4) and the Canon EF Lens Catalog (7D Mark II). Mirrorless cameras, such as the Panasonic GH4, 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.

Concerning battery life, the GH4 gets 500 shots out of its DMW-BLF19 battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N power pack.

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 camera comparisons 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 GH4 was launched at a somewhat lower price (by 17 percent) than the 7D Mark II, 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.

Sensor comparison: Panasonic GH4 vs Canon 7D 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GH4 features a Four Thirds sensor and the Canon 7D II an APS-C sensor. The sensor area in the 7D Mark II is 49 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the GH4 has a native 4:3 aspect ratio, while the one in the 7D Mark II offers a 3:2 aspect.

Panasonic GH4 and Canon 7D II sensor measures

With 20MP, the 7D Mark II offers a higher resolution than the GH4 (15.9MP), but the 7D Mark II nevertheless has larger individual pixels (pixel pitch of 4.10μm versus 3.76μm for the GH4) due to its larger sensor. Moreover, the 7D Mark II is a somewhat more recent model (by 7 months) than the GH4, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

GH4 versus 7D Mark II MP

For most 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 GH4 has a notably higher overall DXO score than the 7D Mark II (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 1 EV in additional dynamic range, 0.5 stops of reduced 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GH4 provides a higher video resolution than the 7D Mark II. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison: Panasonic GH4 vs Canon 7D II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH4 has an electronic viewfinder (2359k dots), while the 7D Mark II 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 adjacent table lists some of the other core features of the Panasonic GH4 and Canon 7D II along with similar information for a selection of comparators.

The 7D Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the GH4 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GH4 was succeeded by the Panasonic GH5.

Review summary: Panasonic GH4 vs Canon 7D II

So what conclusions can be drawn? Is the Panasonic GH4 better than the Canon 7D II or vice versa? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-GH4:

  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (133x93mm vs 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 350g or 38 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2014).

Advantages of the Canon EOS 7D Mark II:

  • More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (670 versus 500) out of a single battery charge.
  • More modern: Was introduced somewhat (7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GH4 is the clear winner of the match-up (12 : 6 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.

GH4 12:06 7D Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GH4 or the 7D Mark II. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
