Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix P7800 and the Panasonic Lumix DMC-G1? 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 Nikon P7800 and the Panasonic G1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

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 larger (12 percent) than the Nikon P7800. In this context, it is worth noting that neither the P7800 nor the G1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P7800 has a lens built in, whereas the G1 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 G1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the P7800 gets 350 shots out of its Nikon EN-EL14 battery, while the G1 can take 410 images on a single charge of its Panasonic DMW-BLB13 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision 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 P7800 was launched at a lower price than the G1, 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon P7800 features a 1/1.7-inch sensor and the Panasonic G1 a Four Thirds sensor. The sensor area in the G1 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Even though the G1 has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the G1 has a lower pixel density and larger individual pixels (with a pixel pitch of 4.33μm versus 1.89μm for the P7800), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the P7800 is much more recent (by 4 years and 11 months) than the G1, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Nikon Coolpix P7800 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Panasonic Lumix DMC-G1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the P7800 is build around a BSI-CMOS sensor, while the G1 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 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 P7800 indeed provides movie recording capabilities, while the G1 does not. The highest resolution format that the P7800 can use is 1080/30p.

Feature comparison

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 G1 offers a substantially higher resolution than the one in the P7800 (1440k vs 921k dots).

The Nikon P7800 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 P7800 writes its imaging data to SDXC cards, while the G1 uses SDHC cards.

Connectivity comparison

Both the P7800 and the G1 have been discontinued, but can regularly be found used on ebay. The G1 was replaced by the Panasonic G2, while the P7800 does not have a direct successor. Further information on the features and operation of the P7800 and G1 can be found, respectively, in the Nikon P7800 Manual (free pdf) or the online Panasonic G1 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon P7800 and the Panasonic G1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Nikon Coolpix P7800:

• More dynamic range: Captures a larger spectrum of light and dark details (1.4 EV of extra DR).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
• Faster burst: Shoots at higher frequency (8 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 G1 requires a separate lens.
• More compact: Is smaller (119x78mm vs 124x84mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years and 11 months of technical progress since the G1 launch.

Arguments in favor of the Panasonic Lumix DMC-G1:

• Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
• More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 921k dots).
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in September 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the P7800 is the clear winner of the match-up (10 : 5 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Nikon P7800 and the Panasonic G1 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the P7800 and the G1 in practical situations. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
