Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix B600 and the Panasonic Lumix DMC-GM1? 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 B600 and the Panasonic GM1. 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 measures are rounded to the nearest millimeter.

The B600 can be obtained in two different colors (black, red), while the GM1 is available in three color-versions (black, silver, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM1 is considerably smaller (46 percent) than the Nikon B600. In this context, it is worth noting that neither the B600 nor the GM1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the B600 has a lens built in, whereas the GM1 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 GM1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the B600 gets 280 shots out of its Nikon EN-EL12 battery, while the GM1 can take 230 images on a single charge of its Panasonic DMW-BLH7 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 B600 was launched at a lower price than the GM1, 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. 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 imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon B600 features a 1/2.3-inch sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the Nikon B600 offers a higher resolution of 15.9 megapixels, compared with 15.8 MP of the Panasonic GM1. 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 1.33μm versus 3.77μm for the GM1). However, it should be noted that the B600 is much more recent (by 5 years and 3 months) than the GM1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the B600 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Nikon Coolpix B600 has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GM1 provides a faster frame rate than the B600. It can shoot movie footage at 1080/60i, while the Nikon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The B600 and the GM1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Nikon B600 and Panasonic GM1 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GM1 has a touchscreen, while the B600 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GM1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GM1 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.

Concerning the storage of imaging data, both the B600 and the GM1 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Nikon Coolpix B600 and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the B600 and the GM1 have been discontinued, but can regularly be found used on ebay. The GM1 was replaced by the Panasonic GM5, while the B600 does not have a direct successor. Further information on the features and operation of the B600 and GM1 can be found, respectively, in the Nikon B600 Manual (free pdf) or the online Panasonic GM1 Manual.

Review summary

So what conclusions can be drawn? Is the Nikon B600 better than the Panasonic GM1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Nikon Coolpix B600:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
• Faster burst: Shoots at higher frequency (7.4 vs 5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the GM1 requires a separate lens.
• Longer lasting: Can take more shots (280 versus 230) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 3 months of technical progress since the GM1 launch.

Advantages of the Panasonic Lumix DMC-GM1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• More detailed LCD: Has a higher resolution rear screen (1036k vs 921k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (99x55mm vs 122x82mm) and will fit more readily into a bag.
• More heavily discounted: Has been around for much longer (launched in October 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the GM1 is the clear winner of the contest (13 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 B600 and the Panasonic GM1 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the B600 and the GM1 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
