Canon 7D vs Panasonic GF3

The Canon EOS 7D and the Panasonic Lumix DMC-GF3 are two digital cameras that were revealed to the public, respectively, in September 2009 and June 2011. The 7D is a DSLR, while the GF3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a Four Thirds (GF3) 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 7D and the Panasonic Lumix DMC-GF3? 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 physical size and weight of the Canon 7D and the Panasonic GF3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The GF3 can be obtained in five different colors (black, brown, pink, red, white), while the 7D is only available in black.

Compare 7D versus GF3 top
Comparison 7D or GF3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF3 is considerably smaller (56 percent) than the Canon 7D. Moreover, the GF3 is substantially lighter (69 percent) than the 7D. It is worth mentioning in this context that the 7D is splash and dust resistant, while the GF3 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 (7D) and the Micro Four Thirds Lens Catalog (GF3). Mirrorless cameras, such as the GF3, 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 7D gets 800 shots out of its LP-E6 battery, while the GF3 can take 300 images on a single charge of its DMW-BLE9 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 GF3 was launched at a markedly lower price (by 68 percent) than the 7D, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 size of the imaging sensor is a crucial determinant 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 7D features an APS-C sensor and the Panasonic GF3 a Four Thirds sensor. The sensor area in the GF3 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 7D has a native 3:2 aspect ratio, while the one in the GF3 offers a 4:3 aspect.

Canon 7D and Panasonic GF3 sensor measures

With 17.9MP, the 7D offers a higher resolution than the GF3 (12MP), but the 7D has marginally smaller individual pixels (pixel pitch of 4.31μm versus 4.33μm for the GF3). Moreover, the GF3 is a somewhat more recent model (by 1 year and 9 months) than the 7D, 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 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Panasonic GF3 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.

The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Panasonic Lumix DMC-GF3 are ISO 160 to ISO 6400 (no boost).

7D versus GF3 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 7D provides substantially higher image quality than the GF3, with an overall score that is 17 points higher. This advantage is based on 1.4 bits higher color depth, 1.7 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GF3 provides a faster frame rate than the 7D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 7D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF3 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon 7D, the Panasonic GF3, and comparable cameras.

One feature that is present on the 7D, but is missing on the GF3 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 7D writes its imaging data to Compact Flash cards, while the GF3 uses SDXC 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 7D and Panasonic Lumix DMC-GF3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 7D has a hotshoe, while the GF3 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 7D (unlike the GF3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 7D and the GF3 have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the GF3 was followed by the Panasonic GF5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.

Review summary

So how do things add up? Which of the two cameras – the Canon 7D or the Panasonic GF3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon EOS 7D:

  • More detail: Offers more megapixels (17.9 vs 12MP) with a 25% higher linear resolution.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.7 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.9 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.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 3.2 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (800 versus 300) 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.
  • More heavily discounted: Has been on the market for longer (launched in September 2009).

ilogo

Reasons to prefer the Panasonic Lumix DMC-GF3:

  • 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 (108x67mm vs 148x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 596g or 69 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 9 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 7D is the clear winner of the match-up (16 : 7 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.

7D 16:07 GF3

How about other alternatives? Do the specifications of the Canon 7D and the Panasonic GF3 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 7D or the GF3. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

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, please note that some of the review sites have changed their methodology and reporting over time.
