Canon G15 vs Nikon D700
The Canon PowerShot G15 and the Nikon D700 are two digital cameras that were announced, respectively, in September 2012 and July 2008. The G15 is a fixed lens compact, while the D700 is a DSLR. The cameras are based on a 1/1.7-inch (G15) and a full frame (D700) sensor. The Canon has a resolution of 12 megapixels, whereas the Nikon provides 12.1 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 PowerShot G15 and the Nikon D700? 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.
An illustration of the physical size and weight of the Canon G15 and the Nikon D700 is provided 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 measures 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 Nikon D700 is considerably larger (122 percent) than the Canon G15. It is noteworthy in this context that the D700 is splash and dust-proof, while the G15 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the D700 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 D700 and their specifications in the Nikon Lens Catalog.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G15 was launched at a lower price than the D700, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 G15 features a 1/1.7-inch sensor and the Nikon D700 a full frame sensor. The sensor area in the D700 is 1900 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.0. The sensor in the G15 has a native 4:3 aspect ratio, while the one in the D700 offers a 3:2 aspect.
With 12.1MP, the D700 offers a higher resolution than the G15 (12MP), but the D700 nevertheless has larger individual pixels (pixel pitch of 8.43μm versus 1.89μm for the G15) due to its larger sensor. However, the G15 is a much more recent model (by 4 years and 2 months) than the D700, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon D700 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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"). Of the two cameras under consideration, the D700 offers substantially better image quality than the G15 (overall score 34 points higher). The advantage is based on 3.6 bits higher color depth, 0.7 EV in additional dynamic range, and 3.8 stops in additional low light sensitivity. 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 can also record movies. The G15 indeed provides movie recording capabilities, while the D700 does not. The highest resolution format that the G15 can use is 1080/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The G15 and the D700 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Canon G15, the Nikon D700, and comparable cameras.

One feature that is present on the D700, but is missing on the G15 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 Nikon D700 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 G15 writes its imaging data to SDXC cards, while the D700 uses Compact Flash cards.
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 G15 and Nikon D700 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D700 (unlike the G15) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the G15 and the D700 have been discontinued, but can regularly be found used on eBay. The D700 was replaced by the Nikon D800, while the G15 was followed by the Canon G16. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon G15 and the Nikon D700? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G15:
- Broader imaging potential: Can record not only still images but also 1080/24p movies.
- Ready to shoot: Comes with a built-in lens, while the D700 requires a separate lens.
- More compact: Is smaller (107x76mm vs 147x123mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the D700).
- 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 2 months of technical progress since the D700 launch.
Arguments in favor of the Nikon D700:
- Better image quality: Scores substantially higher (34 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.6 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (3.8 stops ISO advantage).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 2.1 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (1000 versus 350) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in July 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the D700 is the clear winner of the contest (13 : 7 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 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 Canon G15 and the Nikon D700 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G15 or the D700. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
