Panasonic GX1 versus Panasonic GX7

The Panasonic Lumix DMC-GX1 and the Panasonic Lumix DMC-GX7 are two enthusiast cameras that were announced, respectively, in November 2011 and August 2013. Both the GX1 and the GX7 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 GX1 vs Panasonic GX7

The side-by-side display below illustrates the physical size and weight of the Panasonic GX1 and the Panasonic GX7. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions 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 – the GX1 – 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 Panasonic GX7 is notably larger (11 percent) than the Panasonic GX1. Moreover, the GX7 is markedly heavier (26 percent) than the GX1. In this context, it is worth noting that neither the GX1 nor the GX7 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.

Concerning battery life, the GX1 gets 320 shots out of its DMW-BLD10 battery, while the GX7 can take 350 images on a single charge of its DMW-BLG10 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. 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 GX1 was somewhat cheaper (by 5 percent) than the GX7 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.

 

Sensor comparison: Panasonic GX1 vs Panasonic GX7

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. 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 associated with larger, more expensive camera bodies 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 GX1 and Panasonic GX7 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 GX1 and the GX7 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX7 is a somewhat more recent model (by 1 year and 8 months) than the GX1, and its sensor might have benefitted from technological advances during this time.

GX1 versus GX7 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the GX7 offers substantially better image quality than the GX1 (overall score 15 points higher). The advantage is based on 1.8 bits higher color depth, 1.6 EV in additional dynamic range, and -0 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 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Panasonic GX1 vs Panasonic GX7

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX1 relies on live view and the rear LCD for framing. That said, the GX1 can be equipped with an optional viewfinder – the DMW-LVF2. The table below summarizes some of the other core capabilities of the Panasonic GX1 and Panasonic GX7 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One feature that differentiates the GX7 and the GX1 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the GX1 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX7 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 GX1 and the GX7 write their imaging data to SDXC cards.

  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 4.2 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GX7 is the clear winner of the contest (13 : 2 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

GX1 02:13 GX7

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX1 or the GX7. 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 where reviews by experts come in. 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
