Panasonic G1 versus Panasonic G7

The Panasonic Lumix DMC-G1 and the Panasonic Lumix DMC-G7 are two digital cameras that were revealed to the public, respectively, in September 2008 and May 2015. Both the G1 and the G7 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G1 has a resolution of 12 megapixel, whereas the G7 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: Panasonic G1 vs Panasonic G7

The physical size and weight of the Panasonic G1 and the Panasonic G7 are illustrated in the side-by-side display below. 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. 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 G1 – 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 G7 is somewhat larger (3 percent) than the Panasonic G1. Moreover, the G7 is markedly heavier (14 percent) than the G1. In this context, it is worth noting that neither the G1 nor the G7 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 G1 gets 410 shots out of its DMW-BLB13 battery, while the G7 can take 350 images on a single charge of its DMW-BLC12 power pack.

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

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G1 was somewhat cheaper (by 8 percent) than the G7 at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 G1 vs Panasonic G7

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to 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 G1 and Panasonic G7 sensor measures

While the two cameras under review share the same sensor size, the G7 offers a higher resolution of 15.8 megapixel, compared with 12 MP of the G1. This megapixel advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the G7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.33μm for the G1). However, it should be noted that the G7 is much more recent (by 6 years and 8 months) than the G1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

G1 versus G7 MP

For many 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The G7 indeed provides for movie recording, while the G1 does not. The highest resolution format that the G7 can use is 4K/30p.

 

Feature comparison: Panasonic G1 vs Panasonic G7

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the G7 offers a substantially higher resolution than the one in the G1 (2360k vs 1440k dots). The adjacent table lists some of the other core features of the Panasonic G1 and Panasonic G7 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G7 features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G1 and the G7 have been discontinued, but can regularly be found used on eBay. The G1 was replaced by the Panasonic G2, while the G7 was followed by the Panasonic G85.

Review summary: Panasonic G1 vs Panasonic G7

So how do things add up? Which of the two cameras – the Panasonic G1 or the Panasonic G7 – has the upper hand? The listing below highlights the relative strengths of the two models.


Advantages of the Panasonic Lumix DMC-G1:

  • Faster shutter: Has higher mechanical shutter speed (4001/sec vs 4000/sec) to freeze action.
  • Less heavy: Is lighter (by 50g or 12 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (410 versus 350) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in September 2008).


Arguments in favor of the Panasonic Lumix DMC-G7:

  • More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More modern: Reflects 6 years and 8 months of technical progress since the G1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G7 is the clear winner of the contest (8 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G1 04:08 G7

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G1 and the G7 in practical situations. 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
