Canon 7D vs Panasonic GF1
The Canon EOS 7D and the Panasonic Lumix DMC-GF1 are two digital cameras that were officially introduced in September 2009. The 7D is a DSLR, while the GF1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a Four Thirds (GF1) 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-GF1? 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.
The physical size and weight of the Canon 7D and the Panasonic GF1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF1 is considerably smaller (49 percent) than the Canon 7D. Moreover, the GF1 is substantially lighter (55 percent) than the 7D. It is worth mentioning in this context that the 7D is splash and dust resistant, while the GF1 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 (GF1). Mirrorless cameras, such as the GF1, 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 GF1 can take 380 images on a single charge of its DMW-BLB13 power pack.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GF1 was launched at a markedly lower price (by 56 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 7D features an APS-C sensor and the Panasonic GF1 a Four Thirds sensor. The sensor area in the GF1 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 GF1 offers a 4:3 aspect.
With 17.9MP, the 7D offers a higher resolution than the GF1 (12MP), but the 7D has marginally smaller individual pixels (pixel pitch of 4.31μm versus 4.33μm for the GF1). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
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 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 GF1 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 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-GF1 are ISO 100 to ISO 3200 (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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 7D provides substantially higher image quality than the GF1, with an overall score that is 12 points higher. This advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 7D provides a higher video resolution than the GF1. It can shoot video footage at 1080/30p, while the Panasonic is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 7D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The adjacent table lists some of the other core features of the Canon 7D and Panasonic GF1 along with similar information for a selection of comparators.

One feature that is present on the 7D, but is missing on the GF1 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 GF1 uses SDHC cards.
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-GF1 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 microphone port, which is missing on the GF1. 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 7D (unlike the GF1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 7D and the GF1 have been discontinued, but can regularly be found used on ebay. The 7D was replaced by the Canon 7D Mark II, while the GF1 was followed by the Panasonic DMC-GF2. Further information on the features and operation of the 7D and GF1 can be found, respectively, in the Canon 7D Manual (free pdf) or the online Panasonic GF1 Manual.
So what is the bottom line? Is the Canon 7D better than the Panasonic GF1 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages 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 (12 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- 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 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (800 versus 380) 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.
Arguments in favor of the Panasonic Lumix DMC-GF1:
- More compact: Is smaller (119x71mm vs 148x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 475g or 55 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 (56 percent cheaper at launch).
If the count of relative strengths (bullet points above) is taken as a measure, the 7D is the clear winner of the match-up (14 : 4 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 7D and the Panasonic GF1 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 GF1. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
