Canon 1D X vs Panasonic GF2

The Canon EOS-1D X and the Panasonic Lumix DMC-GF2 are two digital cameras that were officially introduced, respectively, in October 2011 and November 2010. The 1DX is a DSLR, while the GF2 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1DX) and a Four Thirds (GF2) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 12 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-1D X and the Panasonic Lumix DMC-GF2? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 1D X and the Panasonic GF2. 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.

The GF2 can be obtained in four different colors (black, silver, red, white), while the 1DX is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF2 is considerably smaller (71 percent) than the Canon 1D X. Moreover, the GF2 is substantially lighter (80 percent) than the 1DX. It is worth mentioning in this context that the 1DX is splash and dust resistant, while the GF2 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 compare the optics available for the two cameras in the Canon EF Lens Catalog (1DX) and the Micro Four Thirds Lens Catalog (GF2). Mirrorless cameras, such as the GF2, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 1DX gets 1120 shots out of its Canon LP-E4N battery, while the GF2 can take 300 images on a single charge of its Panasonic DMW-BLD10 power pack. As can be seen in the images above, the 1DX has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 GF2 was launched at a markedly lower price (by 92 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D X features a full frame sensor and the Panasonic GF2 a Four Thirds sensor. The sensor area in the GF2 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 1DX has a native 3:2 aspect ratio, while the one in the GF2 offers a 4:3 aspect.

With 17.9MP, the 1DX offers a higher resolution than the GF2 (12MP), but the 1DX nevertheless has larger individual pixels (pixel pitch of 6.95μm versus 4.33μm for the GF2) due to its larger sensor. Moreover, the 1DX is a somewhat more recent model (by 11 months) than the GF2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 1D X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1DX for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Panasonic GF2 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon EOS-1D X has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Panasonic Lumix DMC-GF2 are ISO 100 to ISO 6400 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under review, the 1DX provides substantially higher image quality than the GF2, with an overall score that is 28 points higher. This advantage is based on 2.6 bits higher color depth, 1.5 EV in additional dynamic range, and 2.5 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 GF2 provides a faster frame rate than the 1DX. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1DX has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF2 relies on live view and the rear LCD for framing. That said, the GF2 can be equipped with an optional viewfinder – the DMW-LVF1. The adjacent table lists some of the other core features of the Canon 1D X and Panasonic GF2 along with similar information for a selection of comparators.

One feature that is present on the 1DX, but is missing on the GF2 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 1DX writes its imaging data to Compact Flash cards, while the GF2 uses SDXC cards. The 1DX features dual card slots, which can be very useful in case a memory card fails. In contrast, the GF2 only has one slot.

Connectivity comparison

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-1D X and Panasonic Lumix DMC-GF2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1DX has a microphone port, which is missing on the GF2. 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 1D X (unlike the GF2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1DX and the GF2 have been discontinued, but can regularly be found used on ebay. The GF2 was replaced by the Panasonic GF3, while the 1DX was followed by the Canon 1DX Mark II. Further information on the features and operation of the 1DX and GF2 can be found, respectively, in the Canon 1D X Manual (free pdf) or the online Panasonic GF2 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1D X and the Panasonic GF2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS-1D X:

• More detail: Offers more megapixels (17.9 vs 12MP) with a 25% higher linear resolution.
• Better image quality: Scores substantially higher (28 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.5 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control 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 (1040k vs 460k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (14 vs 2.6 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1120 versus 300) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Is somewhat more recent (announced 11 months after the GF2).

Arguments in favor of the Panasonic Lumix DMC-GF2:

• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More compact: Is smaller (113x68mm vs 158x168mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 1241g or 80 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in November 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the 1DX is the clear winner of the match-up (18 : 8 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 1D X and the Panasonic GF2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1DX or the GF2 perform in practice. 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.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
