Panasonic GM5 versus Canon G1 X Mark II

The Panasonic Lumix DMC-GM5 and the Canon PowerShot G1 X Mark II are two digital cameras that were officially introduced, respectively, in September 2014 and February 2014. The GM5 is a mirrorless interchangeable lens camera, while the G1X Mark II is a fixed lens compact. The cameras are based on a Four Thirds (GM5) and an 1.5-inch (G1X Mark II) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 13 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 GM5 vs Canon G1 X Mark II

An illustration of the physical size and weight of the Panasonic GM5 and the Canon G1 X Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size 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 GM5 – 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 Canon G1 X Mark II is considerably larger (45 percent) than the Panasonic GM5. In this context, it is worth noting that neither the GM5 nor the G1X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II has a lens build in, whereas the GM5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the GM5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GM5 gets 220 shots out of its DMW-BLH7 battery, while the G1X Mark II can take 240 images on a single charge of its NB-12L power pack.

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

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 GM5 vs Canon G1 X Mark II

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GM5 features a Four Thirds sensor and the Canon G1 X Mark II an 1.5-inch sensor. The sensor area in the G1X Mark II is 16 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.85. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic GM5 and Canon G1 X Mark II sensor measures

Despite having a smaller sensor, the Panasonic GM5 offers a higher resolution of 15.8 megapixel, compared with 13 MP of the Canon G1 X Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.49μm for the G1X Mark II). However, it should be noted that the GM5 is a somewhat more recent model (by 7 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

GM5 versus G1X Mark II MP

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 GM5 has a notably higher overall DXO score than the G1X Mark II (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.9 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. 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 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 GM5 provides a higher frame rate than the G1X Mark II. It can shoot video footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Panasonic GM5 vs Canon G1 X Mark II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GM5 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Panasonic GM5 and Canon G1 X Mark II in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark II has one, while the GM5 does not. While the build-in flash of the G1X Mark II is not very powerful, it can at times be useful as a fill-in light.

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 completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GM5 and the G1X Mark II write their imaging data to SDXC cards.

ilogo

Advantages of the Canon PowerShot G1 X Mark II:

  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Ready to shoot: Has an integrated lens, whereas the GM5 necessitates an extra lens.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in February 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the GM5 comes out slightly ahead of the G1X Mark II (9 : 8 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.

GM5 09:08 G1X Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the GM5 or the G1X Mark II 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
