Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark IV and the Panasonic Lumix DMC-GF7? 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 Mark IV and the Panasonic GF7. 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.

The GF7 can be obtained in two different colors (black, pink), while the 1D Mark IV 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 GF7 is considerably smaller (72 percent) than the Canon 1D Mark IV. Moreover, the GF7 is substantially lighter (78 percent) than the 1D Mark IV. It is worth mentioning in this context that the 1D Mark IV is splash and dust resistant, while the GF7 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 (1D Mark IV) and the Micro Four Thirds Lens Catalog (GF7). Mirrorless cameras, such as the GF7, 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 1D Mark IV gets 1500 shots out of its Canon LP-E4 battery, while the GF7 can take 230 images on a single charge of its Panasonic DMW-BLH7 power pack. As can be seen in the images above, the 1D Mark IV 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GF7 was launched at a markedly lower price (by 90 percent) than the 1D Mark IV, 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

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Panasonic GF7 a Four Thirds sensor. The sensor area in the GF7 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D Mark IV has a native 3:2 aspect ratio, while the one in the GF7 offers a 4:3 aspect.

With 16MP, the 1D Mark IV offers a slightly higher resolution than the GF7 (15.8MP), but the 1D Mark IV nevertheless has larger individual pixels (pixel pitch of 5.70μm versus 3.77μm for the GF7) due to its larger sensor. However, the GF7 is a much more recent model (by 5 years and 3 months) than the 1D Mark IV, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Canon EOS-1D Mark IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Panasonic Lumix DMC-GF7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

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.

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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GF7 provides a faster frame rate than the 1D Mark IV. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 1D Mark IV has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF7 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 1D Mark IV and Panasonic GF7 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the 1D Mark IV, but is missing on the GF7 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GF7 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The 1D Mark IV writes its imaging data to Compact Flash or SDHC cards, while the GF7 uses SDXC cards. The 1D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the GF7 only has one slot. The GF7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark IV cannot take advantage of Ultra High Speed SD cards.

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 Mark IV and Panasonic Lumix DMC-GF7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1D Mark IV has a hotshoe, while the GF7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Canon 1D Mark IV (unlike the GF7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark IV and the GF7 have been discontinued, but can regularly be found used on ebay. The GF7 was replaced by the Panasonic GX850, while the 1D Mark IV does not have a direct successor. Further information on the features and operation of the 1D Mark IV and GF7 can be found, respectively, in the Canon 1D Mark IV Manual (free pdf) or the online Panasonic GF7 Manual.

Review summary

So what is the bottom line? Is the Canon 1D Mark IV better than the Panasonic GF7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS-1D Mark IV:

• 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.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/500s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 5.8 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 (1500 versus 230) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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 heavily discounted: Has been available for much longer (launched in October 2009).

Advantages of the Panasonic Lumix DMC-GF7:

• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (107x65mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 964g or 78 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.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
• More modern: Reflects 5 years and 3 months of technical progress since the 1D Mark IV launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GF7 emerges as the winner of the match-up (15 : 12 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Mark IV and the Panasonic GF7 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 1D Mark IV or the GF7 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 assessments were made in relation to similar cameras of the same technological generation.
