Canon 100D vs Pentax K-3
The Canon EOS 100D (called Canon SL1 in some regions) and the Pentax K-3 are two digital cameras that were officially introduced, respectively, in March 2013 and October 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 17.9 megapixels, whereas the Pentax provides 24.1 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 EOS 100D and the Pentax K-3? 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.
The physical size and weight of the Canon 100D and the Pentax K-3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The 100D can be obtained in two different colors (black, white), while the K-3 is also available in two color-versions, but different ones (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 is notably larger (23 percent) than the Canon 100D. Moreover, the K-3 is substantially heavier (97 percent) than the 100D. It is noteworthy in this context that the K-3 is splash and dust-proof, while the 100D does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

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 100D was launched at a markedly lower price (by 58 percent) than the K-3, which puts it into a different market segment. 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.
The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-3 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (100D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24.1MP, the K-3 offers a higher resolution than the 100D (17.9MP), but the K-3 has smaller individual pixels (pixel pitch of 3.90μm versus 4.31μm for the 100D). Yet, the K-3 is a somewhat more recent model (by 6 months) than the 100D, 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 K-3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-3 for good quality output (200 dots per inch) amounts to 30.1 x 20 inch or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inch or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inch or 50.9 x 33.9 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inch or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inch or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inch or 43.9 x 29.3 cm for excellent quality prints.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D 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 Pentax K-3 are ISO 100 to ISO 51200 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the K-3 offers substantially better image quality than the 100D (overall score 17 points higher). The advantage is based on 1.9 bits higher color depth, 2.1 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the K-3 provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 100D and the K-3 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 viewfinder in the K-3 offers a wider field of view (100%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-3 has a higher magnification (0.63x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 100D and Pentax K-3 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the K-3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Pentax K-3 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 100D and the K-3 write their files to SDXC cards. The K-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 100D 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 EOS 100D and Pentax K-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-3 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 100D lacks such a headphone port.
Studio photographers will appreciate that the Pentax K-3 (unlike the 100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 100D and the K-3 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the K-3 was followed by the Pentax K-3 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.
So what is the bottom line? Which of the two cameras – the Canon 100D or the Pentax K-3 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the K-3 is the clear winner of the contest (22 : 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 100D and the Pentax K-3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 100D or the K-3 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.
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.

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.|
The review scores listed above should be treated with care, 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 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.
