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 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 G1 provides 12 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 G9 vs Panasonic G1

The physical size and weight of the Panasonic G9 and the Panasonic G1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth 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 G9 – represents the basis or 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 G1 is notably smaller (22 percent) than the Panasonic G9. Moreover, the 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 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.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the G1 can take 410 images on a single charge of its DMW-BLB13 power pack.

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

Any camera purchase will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1 was launched at a markedly lower price (by 65 percent) than the G9, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Panasonic G9 vs Panasonic G1

The size of the sensor inside a digital camera is one of the key determinants 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. 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 G9 and Panasonic G1 sensor measures

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 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 G1). In this context, it should be noted, however, that the G9 is much more recent (by 9 years and 1 month) than the 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 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).

G9 versus G1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

Many modern cameras are not only capable of taking still images, but can also record movies. The G9 indeed provides movie recording capabilities, while the G1 does not. The highest resolution format that the G9 can use is 4K/60p.

 

Feature comparison: Panasonic G9 vs Panasonic G1

Apart from body and sensor, cameras can and do differ across a variety 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 G1 (3680k vs 1440k dots). The adjacent table lists some of the other core features of the Panasonic G9 and Panasonic G1 along with similar information for a selection of comparators.

One feature that is present on the G9, but is missing on the G1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G9 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).

The G9 writes its imaging data to SDXC cards, while the G1 uses SDHC cards. The G9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1 only has one slot.

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

Review summary: Panasonic G9 vs Panasonic G1

So how do things add up? Is there a clear favorite between the Panasonic G9 and the Panasonic G1? 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 higher resolution electronic viewfinder (3680k vs 1440k dots).
  • Easier setting verification: Features 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 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 9 years and 1 month of technical progress since the G1 launch.


Advantages of 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 (18 : 6 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.

G9 18:06 G1

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G9 or the G1 handle or perform in practice. 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 hands-on reviews by experts 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).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
