Panasonic G9 versus Panasonic G1

The Panasonic Lumix DC-G9 and the Panasonic Lumix DMC-G1 are two digital cameras that were revealed to the public, respectively, in November 2017 and September 2008. Both the G9 and the Lumix G1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G9 has a resolution of 20.2 megapixel, whereas the Lumix G1 provides 12 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Panasonic G1. 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 use the toggle button 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 G9 – 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 G1 is notably smaller (22 percent) than the Panasonic G9. Moreover, the Lumix G1 is substantially lighter (45 percent) than the G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the Lumix G1 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. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Lumix G1 was launched at a markedly lower price (by 65 percent) than the G9, 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

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tent 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.

Sensor size

While the two cameras under review share the same sensor size, the G9 offers a higher resolution of 20.2 megapixel, compared with 12 MP of the Lumix G1. This megapixel advantage translates into a 30 percent gain in linear resolution. On the other hand, these sensor specs imply that the G9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.33μm for the Lumix G1). In this context, it should be noted, however, that the G9 is much more recent (by 9 years and 1 month) than the Lumix G1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the Lumix G1, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

Many modern cameras cannot only take still pictures, but also record videos. The G9 indeed provides movie recording capabilities, while the Lumix G1 does not. The highest resolution format that the G9 can use is 4K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the G9 offers a substantially higher resolution than the one in the Lumix G1 (3680k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Panasonic G9, the Panasonic G1, and comparable cameras.

The G9 is a current model that online retailers, such as amazon, will have in stock. In contrast, the Lumix G1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the Lumix G1 was succeeded by the Panasonic G2.

Summary

So what is the bottom line? Is there a clear favorite between the Panasonic G9 and the Panasonic G9? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DC-G9:

  • More detail: Offers more megapixels (20.2 vs 12MP) with a 30% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Broader imaging potential: Can record not only still images but also 4K/60p movies.
  • More detailed viewfinder: Has a higher resolution electronic viewfinder (3680k vs 1440k dots).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4001/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 3 flaps/sec) to capture the decisive moment.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More modern: Reflects 9 years and 1 month of technical progress since the Lumix G1 launch.

Reasons to prefer the Panasonic Lumix DMC-G1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (124x84mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 298g or 45 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (13 : 6 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.

G9 13:06 Lumix G1

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G9 and the Lumix G1 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 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.
