Panasonic GM1 versus Panasonic GM5

The Panasonic Lumix DMC-GM1 and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in October 2013 and September 2014. Both the GM1 and the GM5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.8 megapixel. 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 GM1 vs Panasonic GM5

The side-by-side display below illustrates the physical size and weight of the Panasonic GM1 and the Panasonic GM5. 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 side – the GM1 – 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 notably larger (9 percent) than the Panasonic GM1. Moreover, the GM5 is slightly heavier (3 percent) than the GM1. In this context, it is worth noting that neither the GM1 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

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 two cameras under review were launched at the same price and fall into the same 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: Panasonic GM1 vs Panasonic GM5

The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic GM1 and Panasonic GM5 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.8 megapixel. This similarity in sensor specs implies that both the GM1 and the GM5 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GM5 is a somewhat more recent model (by 10 months) than the GM1, and its sensor might have benefitted from technological advances during this time.

GM1 versus GM5 MP

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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. 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 GM1. It can shoot movie footage at 1080/60p, while the GM1 is limited to 1080/60i.

 

Feature comparison: Panasonic GM1 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), which can be very helpful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic GM1, the Panasonic GM5, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Panasonic GM1 vs Panasonic GM5

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GM1 and the Panasonic GM5? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC-GM1:

  • More detailed LCD: Has a higher resolution rear screen (1036k vs 921k dots).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More heavily discounted: Has been on the market for longer (launched in October 2013).


Reasons to prefer the Panasonic Lumix DMC-GM5:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (5.8 vs 5 flaps/sec) to capture the decisive moment.
  • More modern: Was introduced somewhat (10 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the GM5 comes out slightly ahead of the GM1 (4 : 3 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GM1 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. This is where reviews by experts come in. 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).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
