Canon 100D versus Panasonic GM5

The Canon EOS 100D (called Canon SL1 in some regions) and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in March 2013 and September 2014. The 100D is a DSLR, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (100D) and a Four Thirds (GM5) sensor. The Canon has a resolution of 17.9 megapixel, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 100D vs Panasonic GM5

The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Panasonic GM5. 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 dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 100D – represents the basis for the calculations across all the size and weight measures).

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 (44 percent) than the Canon 100D. Moreover, the GM5 is substantially lighter (48 percent) than the 100D. In this context, it is worth noting that neither the 100D 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (100D) 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 100D gets 380 shots out of its LP-E12 battery, while the GM5 can take 220 images on a single charge of its DMW-BLH7 power pack.

Any camera purchase will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 100D was launched at a markedly lower price (by 27 percent) than the GM5, 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.

 

Sensor comparison: Canon 100D vs Panasonic GM5

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 100D 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 100D has a native 3:2 aspect ratio, while the one in the GM5 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 100D and Panasonic GM5 sensor measures

With 17.9MP, the 100D offers a higher resolution than the GM5 (15.8MP), but the 100D 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 somewhat more recent model (by 1 year and 5 months) than the 100D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GM5 provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 100D vs Panasonic GM5

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GM5 has an electronic viewfinder (1166k dots), while the 100D 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 adjacent table lists some of the other core features of the Canon 100D and Panasonic GM5 along with similar information for a selection of comparators.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GM5 features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the 100D and the GM5 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the GM5 was followed by the ...

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 100D or the GM5 handle or perform in practice. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
