Panasonic G7 versus Canon 1D X

The Panasonic Lumix DMC-G7 and the Canon EOS-1D X are two digital cameras that were officially introduced, respectively, in May 2015 and October 2011. The G7 is a mirrorless interchangeable lens camera, while the 1DX is a DSLR. The cameras are based on a Four Thirds (G7) and a full frame (1DX) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 17.9 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 G7 vs Canon 1D X

The side-by-side display below illustrates the physical size and weight of the Panasonic G7 and the Canon 1D X. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 side – the G7 – represents the basis for the calculations 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 1D X is considerably larger (147 percent) than the Panasonic G7. Moreover, the 1DX is substantially heavier (278 percent) than the G7. It is noteworthy in this context that the 1DX is splash and dust-proof, while the G7 does not feature any corresponding weather-sealing.

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 (G7) and the Canon EF Lens Catalog (1DX). Mirrorless cameras, such as the Panasonic G7, 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 G7 gets 350 shots out of its DMW-BLC12 battery, while the 1DX can take 1120 images on a single charge of its LP-E4N power pack. As can be seen in the images above, the 1DX has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 camera’s price is obviously a critical decision-making factor. 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 G7 was launched at a markedly lower price (by 90 percent) than the 1DX, which puts it into a different market segment. 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: Panasonic G7 vs Canon 1D X

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G7 features a Four Thirds sensor and the Canon 1D X a full frame sensor. The sensor area in the 1DX is 284 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the G7 has a native 4:3 aspect ratio, while the one in the 1DX offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Panasonic G7 and Canon 1D X sensor measures

With 17.9MP, the 1DX offers a higher resolution than the G7 (15.8MP), but the 1DX nevertheless has larger individual pixels (pixel pitch of 6.95μm versus 3.77μm for the G7) due to its larger sensor. However, the G7 is a much more recent model (by 3 years and 7 months) than the 1DX, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

G7 versus 1DX MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7 provides a higher video resolution than the 1DX. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/30p.

 

Feature comparison: Panasonic G7 vs Canon 1D X

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G7 has an electronic viewfinder (2360k dots), while the 1DX 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 G7 and Canon 1D X along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G7 has one, while the 1DX does not. While the build-in flash of the G7 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G7 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The G7 writes its imaging data to SDXC cards, while the 1DX uses Compact Flash cards. The 1DX features dual card slots, which can be very useful in case a memory card fails. In contrast, the G7 only has one slot.

ilogo

Arguments in favor of the Canon EOS-1D X:

  • More detail: Has more megapixels (17.9 vs 15.8MP), which boosts linear resolution by 8%.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features 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.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 7 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (1120 versus 350) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in October 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the G7 comes out slightly ahead of the 1DX (12 : 11 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.

G7 12:11 1DX

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G7 or the 1DX. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
