Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Panasonic Lumix DMC-GH1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G9 X and the Panasonic GH1. 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.

The G9X can be obtained in two different colors (black, silver), while the GH1 is also available in two color-versions, but different ones (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH1 is considerably larger (96 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the GH1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens built in, whereas the GH1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GH1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G9X gets 220 shots out of its Canon NB-13L battery, while the GH1 can take 300 images on a single charge of its Panasonic DMW-BLB13 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. 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 G9X was launched at a lower price than the GH1, despite having a lens built in. 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

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.

Of the two cameras under consideration, the Canon G9 X features an one-inch sensor and the Panasonic GH1 a Four Thirds sensor. The sensor area in the GH1 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G9X has a native 3:2 aspect ratio, while the one in the GH1 offers a 4:3 aspect.

Despite having a smaller sensor, the Canon G9 X offers a higher resolution of 20 megapixels, compared with 12 MP of the Panasonic GH1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.33μm for the GH1). However, it should be noted that the G9X is much more recent (by 6 years and 7 months) than the GH1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G9 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic GH1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the G9X is build around a BSI-CMOS sensor, while the GH1 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X provides a higher frame rate than the GH1. It can shoot video footage at 1080/60p, while the Panasonic is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH1 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G9 X and Panasonic GH1 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X has a touchscreen, while the GH1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G9 X has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The G9X writes its imaging data to SDXC cards, while the GH1 uses SDHC cards. The G9X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH1 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G9 X and Panasonic Lumix DMC-GH1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X offers wifi support, while the GH1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G9X and the GH1 have been discontinued, but can regularly be found used on ebay. The GH1 was replaced by the Panasonic GH2, while the G9X was followed by the Canon G9 X Mark II. Further information on the features and operation of the G9X and GH1 can be found, respectively, in the Canon G9 X Manual (free pdf) or the online Panasonic GH1 Manual.

Review summary

So what conclusions can be drawn? Is the Canon G9 X better than the Panasonic GH1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot G9 X:

• More detail: Offers more megapixels (20 vs 12MP) with a 32% higher linear resolution.
• More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• 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 burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has a lens built-in, whereas the GH1 requires a separate lens.
• More compact: Is smaller (98x58mm vs 124x90mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the GH1).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.

• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (300 versus 220) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in March 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the G9X is the clear winner of the match-up (17 : 10 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon G9 X and the Panasonic GH1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G9X or the GH1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age.
