Canon 1D versus Panasonic GM5

The Canon EOS-1D and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in September 2001 and September 2014. The 1D is a DSLR, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D) and a Four Thirds (GM5) sensor. The Canon has a resolution of 4.1 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 1D vs Panasonic GM5

The side-by-side display below illustrates the physical size and weight of the Canon 1D and the Panasonic GM5. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 1D – 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 (76 percent) than the Canon 1D. Moreover, the GM5 is substantially lighter (87 percent) than the 1D. It is worth mentioning in this context that the 1D is splash and dust resistant, while the GM5 does not feature any corresponding weather-sealing.

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 (1D) 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 1D gets 500 shots out of its NP-E3 battery, while the GM5 can take 220 images on a single charge of its DMW-BLH7 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 GM5 was launched at a markedly lower price (by 88 percent) than the 1D, which puts it into a different market segment. 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: Canon 1D vs Panasonic GM5

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 Canon 1D features an APS-H sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 is 59 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D has a native 3:2 aspect ratio, while the one in the GM5 offers a 4:3 aspect.

Canon 1D and Panasonic GM5 sensor measures

Despite having a smaller sensor, the GM5 offers a higher resolution of 15.8 megapixel, compared with 4.1 MP of the 1D. 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 11.56μm for the 1D). However, it should be noted that the GM5 is much more recent (by 12 years and 11 months) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

Many modern cameras cannot only take still pictures, but also record videos. The GM5 indeed provides for movie recording, while the 1D does not. The highest resolution format that the GM5 can use is 1080/60p.

 

Feature comparison: Canon 1D vs Panasonic GM5

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 1D 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 table below summarizes some of the other core capabilities of the Canon 1D and Panasonic GM5 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D or the GM5. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. 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 review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
