Panasonic GF5 vs Canon 100D

The Panasonic Lumix DMC-GF5 and the Canon EOS 100D (labelled Canon SL1 in some countries) are two digital cameras that were announced, respectively, in April 2012 and March 2013. The GF5 is a mirrorless interchangeable lens camera, while the 100D is a DSLR. The cameras are based on a Four Thirds (GF5) and an APS-C (100D) sensor. The Panasonic has a resolution of 12 megapixels, whereas the Canon provides 17.9 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 Panasonic Lumix DMC-GF5 and the Canon EOS 100D? 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 Panasonic GF5 and the Canon 100D. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The GF5 can be obtained in three different colors (black, red, white), while the 100D is available in two color-versions (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 100D is considerably larger (47 percent) than the Panasonic GF5. Moreover, the 100D is substantially heavier (52 percent) than the GF5. In this context, it is worth noting that neither the GF5 nor the 100D are weather-sealed.

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 Micro Four Thirds Lens Catalog (GF5) and the Canon EF Lens Catalog (100D). Mirrorless cameras, such as the Panasonic GF5, 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 GF5 gets 360 shots out of its Panasonic DMW-BLE9 battery, while the 100D can take 380 images on a single charge of its Canon LP-E12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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 GF5 was somewhat cheaper (by 9 percent) than the 100D at launch, but both cameras fall into the same price category. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Panasonic GF5 features a Four Thirds sensor and the Canon 100D an APS-C sensor. The sensor area in the 100D is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the GF5 has a native 4:3 aspect ratio, while the one in the 100D offers a 3:2 aspect.

With 17.9MP, the 100D offers a higher resolution than the GF5 (12MP), but the 100D has marginally smaller individual pixels (pixel pitch of 4.31μm versus 4.33μm for the GF5). Yet, the 100D is a somewhat more recent model (by 11 months) than the GF5, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D 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 GF5 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 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Panasonic Lumix DMC-GF5 has a native sensitivity range from ISO 160 to ISO 6400, which can be extended to ISO 160-12800. The corresponding ISO settings for the Canon EOS 100D are ISO 100 to ISO 12800, 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the 100D offers substantially better image quality than the GF5 (overall score 13 points higher). The advantage is based on 1.3 bits higher color depth, 1.3 EV in additional dynamic range, and 0.6 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GF5 provides a higher frame rate than the 100D. It can shoot video 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 variety of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF5 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic GF5, the Canon 100D, and comparable cameras.

Concerning the storage of imaging data, both the GF5 and the 100D write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Panasonic Lumix DMC-GF5 and Canon EOS 100D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The GF5 does not feature such a mic input.

Both the GF5 and the 100D have been discontinued, but can regularly be found used on ebay. The GF5 was replaced by the Panasonic GF6, while the 100D was followed by the Canon 200D. Further information on the features and operation of the GF5 and 100D can be found, respectively, in the Panasonic GF5 Manual (free pdf) or the online Canon 100D Manual.

Review summary

So what is the bottom line? Is the Panasonic GF5 better than the Canon 100D or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Panasonic Lumix DMC-GF5:

• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• More compact: Is smaller (108x67mm vs 117x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 140g or 34 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• More heavily discounted: Has been on the market for longer (launched in April 2012).

Reasons to prefer the Canon EOS 100D:

• More detail: Has more megapixels (17.9 vs 12MP), which boosts linear resolution by 25%.
• Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• 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.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• Faster burst: Shoots at higher frequency (4.9 vs 4 flaps/sec) to capture the decisive moment.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Was introduced somewhat (11 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 100D is the clear winner of the contest (12 : 5 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 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 Panasonic GF5 and the Canon 100D place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 GF5 or the 100D 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 expert reviews 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
