Canon 1D Mark III vs Nikon W150

The Canon EOS-1D Mark III and the Nikon Coolpix W150 are two digital cameras that were revealed to the public, respectively, in February 2007 and April 2019. The 1D Mark III is a DSLR, while the W150 is a fixed lens compact. The cameras are based on an APS-H (1D Mark III) and a 1/3.1-inch (W150) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 13 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark III and the Nikon Coolpix W150? 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 physical size and weight of the Canon 1D Mark III and the Nikon W150 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The W150 can be obtained in five different colors (blue, orange, white, flower, resort), while the 1D Mark III is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon W150 is considerably smaller (70 percent) than the Canon 1D Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, the W150 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the W150 has a lens built in, whereas the 1D Mark III 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 1D Mark III and their specifications in the Canon EF Lens Catalog.

As can be seen in the images above, the 1D Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the W150 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 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 W150 was launched at a lower price than the 1D Mark III, 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 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Nikon W150 a 1/3.1-inch sensor. The sensor area in the W150 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 7.4. The sensor in the 1D Mark III has a native 3:2 aspect ratio, while the one in the W150 offers a 4:3 aspect.

Despite having a smaller sensor, the W150 offers a higher resolution of 13 megapixels, compared with 10.1 MP of the 1D Mark III. 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 1.11μm versus 7.21μm for the 1D Mark III). However, it should be noted that the W150 is much more recent (by 12 years and 2 months) than the 1D Mark III, 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 W150 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon W150 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the W150 for good quality output (200 dots per inch) amounts to 20.8 x 15.6 inches or 52.8 x 39.6 cm, for very good quality (250 dpi) 16.6 x 12.5 inches or 42.3 x 31.7 cm, and for excellent quality (300 dpi) 13.9 x 10.4 inches or 35.2 x 26.4 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Nikon Coolpix W150 are ISO 125 to ISO 1600 (no boost).

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. The W150 indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the W150 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1D Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the W150 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 1D Mark III and Nikon W150 along with similar information for a selection of comparators.

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

One feature that is present on the 1D Mark III, but is missing on the W150 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 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 W150 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 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the W150 uses SDXC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the W150 only has one slot.

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 EOS-1D Mark III and Nikon Coolpix W150 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1D Mark III has a hotshoe, while the W150 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Canon 1D Mark III (unlike the W150) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark III and the W150 have been discontinued, but can regularly be found used on ebay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the W150 does not have a direct successor. Further information on the features and operation of the 1D Mark III and W150 can be found, respectively, in the Canon 1D Mark III Manual (free pdf) or the online Nikon W150 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1D Mark III and the Nikon W150? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS-1D Mark III:

• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 4.7 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (2200 versus 220) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in February 2007).

Advantages of the Nikon Coolpix W150:

• More detail: Has more megapixels (13 vs 10.1MP), which boosts linear resolution by 11%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Comes with an integrated lens, while the 1D Mark III requires a separate lens.
• More compact: Is smaller (110x67mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 1D Mark III).
• Easier travel charging: Can be conveniently charged via its USB port.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• 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 12 years and 2 months of technical progress since the 1D Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark III emerges as the winner of the contest (17 : 14 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 1D Mark III and the Nikon W150 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the 1D Mark III or the W150 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
