Body comparison: Canon M10 vs Nikon W300
The side-by-side display below illustrates the physical size and weight of the Canon M10 and the Nikon W300. 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.
The M10 can be obtained in two different colors (black, white), while the W300 is available in three color-versions (black, orange, yellow).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon W300 is somewhat larger (2 percent) than the Canon M10. It is noteworthy in this context that the W300 is splash and dust-proof, while the M10 does not feature any corresponding weather-sealing. More than that, the W300 is water-proof up to 30m and can, thus, be used for underwater photography.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the W300 has a lens built in, whereas the M10 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the M10 gets 255 shots out of its LP-E12 battery, while the W300 can take 280 images on a single charge of its EN-EL12 power pack. The power pack in the W300 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 W300 was launched at a lower price than the M10, 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: Canon M10 vs Nikon W300
The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon M10 features an APS-C sensor and the Nikon W300 a 1/2.3-inch sensor. The sensor area in the W300 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the M10 has a native 3:2 aspect ratio, while the one in the W300 offers a 4:3 aspect.
With 17.9MP, the M10 offers a higher resolution than the W300 (15.9MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.33μm for the W300) due to its larger sensor. However, the W300 is a somewhat more recent model (by 1 year and 7 months) than the M10, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The M10 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS M10 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon Coolpix W300 are ISO 125 to ISO 1600, with the possibility to increase the ISO range to 125-6400..
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10 has a touchscreen, while the W300 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M10 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the W300 does not have a selfie-screen.
Concerning the storage of imaging data, both the M10 and the W300 write their files to SDXC cards. The M10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while W300 cannot take advantage of Ultra High Speed SD cards.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
