Canon S120 vs Nikon D7100
The Canon PowerShot S120 and the Nikon D7100 are two digital cameras that were revealed to the public, respectively, in August 2013 and February 2013. The S120 is a fixed lens compact, while the D7100 is a DSLR. The cameras are based on a 1/1.7-inch (S120) and an APS-C (D7100) sensor. The Canon has a resolution of 12 megapixels, whereas the Nikon provides 24 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 S120 and the Nikon D7100? 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 S120 and the Nikon D7100 is provided 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 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 D7100 is considerably larger (147 percent) than the Canon S120. It is noteworthy in this context that the D7100 is splash and dust-proof, while the S120 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the S120 has a lens built in, whereas the D7100 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 D7100 and their specifications in the Nikon Lens Catalog.

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 S120 was launched at a lower price than the D7100, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 S120 features a 1/1.7-inch sensor and the Nikon D7100 an APS-C sensor. The sensor area in the D7100 is 753 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 1.5. The sensor in the S120 has a native 4:3 aspect ratio, while the one in the D7100 offers a 3:2 aspect.
With 24MP, the D7100 offers a higher resolution than the S120 (12MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a somewhat more recent model (by 5 months) than the D7100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon S120 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 S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon D7100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.
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. Of the two cameras under consideration, the D7100 offers substantially better image quality than the S120 (overall score 27 points higher). The advantage is based on 2.9 bits higher color depth, 1.8 EV in additional dynamic range, and 2.4 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.
|Canon G9 X Mark II||1-inch||20.0||5472||3648||1080/60p||21.9||12.5||522||65|
|Canon G9 X||1-inch||20.0||5472||3648||1080/60p||21.5||12.3||495||63|
|Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D7100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the S120 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon S120 and Nikon D7100 in connection with corresponding information for a sample of similar cameras.

|Canon G1 X||optical||n||3.0||922||Swivel||n||1/4000s||1.9||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S120 has a touchscreen, while the D7100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Canon S120 and the Nikon D7100 both have 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 S120 and the D7100 write their files to SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the S120 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 S120 and Nikon D7100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Canon G9 X Mark II||-||stereo||mono||-||-||micro||2.0||Y||Y||Y|
|Canon G9 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
|Canon G1 X Mark II||Y||stereo||mono||-||-||mini||2.0||Y||Y||-|
|Canon G1 X||Y||stereo||mono||-||-||mini||2.0||-||-||-|
It is notable that the S120 offers wifi support, while the D7100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the S120 and the D7100 have been discontinued, but can regularly be found used on eBay. The D7100 was replaced by the Nikon D7200, while the S120 does not have a direct successor. 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 is the bottom line? Which of the two cameras – the Canon S120 or the Nikon D7100 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 is the clear winner of the contest (19 : 10 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 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.

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 S120 and the D7100 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
