Canon 550D vs Panasonic GM5

The Canon EOS 550D (called Canon T2i in some regions) and the Panasonic Lumix DMC-GM5 are two digital cameras that were officially introduced, respectively, in February 2010 and September 2014. The 550D is a DSLR, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (550D) and a Four Thirds (GM5) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 15.8 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Canon 550D and the Panasonic GM5 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.

The GM5 can be obtained in two different colors (black, silver), while the 550D is only available in black.

Size Canon 550D vs Panasonic GM5
Compare 550D versus GM5 top
Comparison 550D or GM5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM5 is considerably smaller (53 percent) than the Canon 550D. Moreover, the GM5 is substantially lighter (60 percent) than the 550D. In this context, it is worth noting that neither the 550D nor the GM5 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 Canon EF Lens Catalog (550D) and the Micro Four Thirds Lens Catalog (GM5). Mirrorless cameras, such as the GM5, 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 550D gets 440 shots out of its LP-E8 battery, while the GM5 can take 220 images on a single charge of its DMW-BLH7 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 550D was somewhat cheaper (by 7 percent) than the GM5 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. 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. 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 550D features an APS-C sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 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 550D has a native 3:2 aspect ratio, while the one in the GM5 offers a 4:3 aspect.

Canon 550D and Panasonic GM5 sensor measures

With 17.9MP, the 550D offers a higher resolution than the GM5 (15.8MP), but the 550D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the GM5) due to its larger sensor. However, the GM5 is a much more recent model (by 4 years and 7 months) than the 550D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D 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 GM5 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The Canon EOS 550D 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-GM5 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.

550D versus GM5 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 GM5 provides a faster frame rate than the 550D. 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 GM5 has an electronic viewfinder (1166k dots), while the 550D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the GM5 offers a wider field of view (100%) than the one in the 550D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 550D has a higher magnification (0.54x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 550D and Panasonic GM5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 550D has one, while the GM5 does not. While the built-in flash of the 550D is not very powerful, it can at times be useful as a fill-in light.

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 GM5 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 Panasonic GM5 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the 550D and the GM5 write their files to SDXC cards. The GM5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 550D cannot take advantage of Ultra High Speed SD cards.

It is notable that the 550D has a microphone port, which is missing on the GM5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the 550D and the GM5 have been discontinued, but can regularly be found used on ebay. The 550D was replaced by the Canon 600D, while the GM5 does not have a direct successor. Further information on the features and operation of the 550D and GM5 can be found, respectively, in the Canon 550D Manual (free pdf) or the online Panasonic GM5 Manual.

  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
  • Longer lasting: Can take more shots (440 versus 220) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More heavily discounted: Has been available for much longer (launched in February 2010).

ilogo

Arguments in favor of the Panasonic Lumix DMC-GM5:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (5.8 vs 3.7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (99x60mm vs 129x98mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 319g or 60 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 4 years and 7 months of technical progress since the 550D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GM5 is the clear winner of the contest (13 : 9 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.

550D 09:13 GM5

How about other alternatives? Do the specifications of the Canon 550D and the Panasonic GM5 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 550D or the GM5. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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.
