Body comparison: Canon 100D vs Canon RP

An illustration of the physical size and weight of the Canon 100D and the Canon RP is provided 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon RP is notably larger (6 percent) than the Canon 100D. Moreover, the Canon RP is markedly heavier (19 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the Canon RP are weather-sealed.

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 Canon RP can take 250 images on a single charge of its LP-E17 power pack. The power pack in the Canon RP can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 100D was launched at a markedly lower price (by 58 percent) than the Canon RP, 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.

 

Sensor comparison: Canon 100D vs Canon RP

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Canon RP a full frame sensor. The sensor area in the Canon RP 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.

Technology-wise, the Canon RP uses a more advanced image processing engine (DIGIC 8) than the 100D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Canon 100D and Canon RP sensor measures

With 26.2MP, the Canon RP offers a higher resolution than the 100D (17.9MP), but the Canon RP nevertheless has larger individual pixels (pixel pitch of 5.74μm versus 4.31μm for the 100D) due to its larger sensor. Moreover, the Canon RP is a much more recent model (by 5 years and 10 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.

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 Canon EOS RP are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400..

100D versus Canon RP MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Canon RP provides a better video resolution than the 100D. It can shoot movie footage at 4K/30p, while the 100D is limited to 1080/30p.

 

Feature comparison: Canon 100D vs Canon RP

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Canon RP has an electronic viewfinder (2360k dots), while the 100D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Canon 100D, the Canon RP, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the Canon RP 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.

The Canon RP has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 100D does not have a selfie-screen.

Concerning the storage of imaging data, both the 100D and the Canon RP write their files to SDXC cards.

 

Connectivity comparison: Canon 100D vs Canon RP

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.

It is notable that the Canon RP 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 Canon RP is a recent model that features in the current product line-up of Canon. 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 Canon RP

So how do things add up? Which of the two cameras – the Canon 100D or the Canon RP – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 100D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Less heavy: Is lighter (by 78g or 16 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (380 versus 250) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (58 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in March 2013).


Reasons to prefer the Canon EOS RP:

  • More detail: Has more megapixels (26.2 vs 17.9MP), which boosts linear resolution by 20%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: Larger sensor generates images with better, more accurate colors.
  • More dynamic range: Capable of capturing a wider spectrum of light and dark details.
  • Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
  • Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 5).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 5 years and 10 months of technical progress since the 100D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the Canon RP is the clear winner of the contest (15 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

100D 06:15 Canon RP

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 100D or the Canon RP handle or 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
