Panasonic G5 versus Canon SL1

The Panasonic Lumix DMC-G5 and the Canon EOS Rebel SL1 (labelled Canon 100D in some countries) are two digital cameras that were officially introduced, respectively, in July 2012 and March 2013. The G5 is a mirrorless interchangeable lens camera, while the SL1 is a DSLR. The cameras are based on a Four Thirds (G5) and an APS-C (SL1) sensor. The Panasonic has a resolution of 15.9 megapixel, whereas the Canon provides 17.9 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: Panasonic G5 vs Canon SL1

The side-by-side display below illustrates the physical size and weight of the Panasonic G5 and the Canon SL1. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 – the G5 – represents 100 percent 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 Canon SL1 is notably larger (7 percent) than the Panasonic G5. Moreover, the SL1 is slightly heavier (3 percent) than the G5. In this context, it is worth noting that neither the G5 nor the SL1 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 Micro Four Thirds Lens Catalog (G5) and the Canon EF Lens Catalog (SL1). Mirrorless cameras, such as the Panasonic G5, 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 G5 gets 320 shots out of its DMW-BLC12 battery, while the SL1 can take 380 images on a single charge of its LP-E12 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SL1 was somewhat cheaper (by 8 percent) than the G5 at launch, but both cameras fall into the same price category. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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: Panasonic G5 vs Canon SL1

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

Of the two cameras under consideration, the Panasonic G5 features a Four Thirds sensor and the Canon SL1 an APS-C sensor. The sensor area in the SL1 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 G5 has a native 4:3 aspect ratio, while the one in the SL1 offers a 3:2 aspect.

Panasonic G5 and Canon SL1 sensor measures

With 17.9MP, the SL1 offers a higher resolution than the G5 (15.9MP), but the SL1 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.76μm for the G5) due to its larger sensor. Moreover, the SL1 is a somewhat more recent model (by 8 months) than the G5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G5 provides a higher frame rate than the SL1. It can shoot video footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Panasonic G5 vs Canon SL1

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5 has an electronic viewfinder (1440k dots), while the SL1 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 following table reports on some other key feature differences and similarities of the Panasonic G5, the Canon SL1, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

G5 06:06 SL1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G5 or the SL1 handle or 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. This is why hands-on reviews by experts are important.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
