Canon 100D vs Pentax K-1 II

The Canon EOS 100D (called Canon SL1 in some regions) and the Pentax K-1 II are two digital cameras that were announced, respectively, in March 2013 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (100D) and a full frame (K-1 II) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Pentax provides 36.2 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 II is notably larger (42 percent) than the Canon 100D. Moreover, the K-1 II is substantially heavier (148 percent) than the 100D. It is noteworthy in this context that the K-1 II 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.

Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the K-1 II can take 670 images on a single charge of its D-LI90 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 100D was launched at a markedly lower price (by 73 percent) than the K-1 II, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 100D vs Pentax K-1 II

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Pentax K-1 II a full frame sensor. The sensor area in the K-1 II is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 100D and Pentax K-1 II sensor measures

With 36.2MP, the K-1 II offers a higher resolution than the 100D (17.9MP), but the K-1 II nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 4.31μm for the 100D) due to its larger sensor. Moreover, the K-1 II is a much more recent model (by 4 years and 11 months) than the 100D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

Unlike the 100D, the K-1 II has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

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-1 II are ISO 100 to ISO 819200 (no boost).

100D versus K-1 II MP

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, but the K-1 II provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 100D vs Pentax K-1 II

Apart from body and sensor, cameras can and do differ across a range of features. The 100D and the K-1 II 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 table below summarizes some of the other core capabilities of the Canon 100D and Pentax K-1 II in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the K-1 II does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 100D and the K-1 II write their files to SDXC cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 100D only has one slot.

Connectivity comparison: Canon 100D vs Pentax K-1 II

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-1 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.

The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the 100D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 100D was succeeded by the Canon 200D.


Review summary: Canon 100D vs Pentax K-1 II

So what conclusions can be drawn? Is the Canon 100D better than the Pentax K-1 II or vice versa? The listing below highlights the relative strengths of the two models.

  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 4 years and 11 months of technical progress since the 100D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the K-1 II is the clear winner of the contest (19 : 8 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.

100D 08:19 K-1 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the K-1 II handle or perform in practice. 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
