Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon R100 and the Panasonic S1R II. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Canon R100 vs Panasonic S1R II
Compare R100 versus S1R II top
Comparison R100 or S1R II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1R II is notably larger (37 percent) than the Canon R100. Moreover, the S1R II is substantially heavier (123 percent) than the R100. It is noteworthy in this context that the S1R II is splash and dust-proof, while the R100 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 R100 gets 400 shots out of its Canon LP-E17 battery, while the S1R II can take 350 images on a single charge of its Panasonic DMW-BLK22 power pack. The power pack in the S1R II can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 R100 was launched at a markedly lower price (by 85 percent) than the S1R II, 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

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 R100 features an APS-C sensor and the Panasonic S1R II a full frame sensor. The sensor area in the S1R II is 158 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 R100 and Panasonic S1R II sensor measures

With 44.2MP, the S1R II offers a higher resolution than the R100 (24MP), but the S1R II nevertheless has larger individual pixels (pixel pitch of 4.40μm versus 3.72μm for the R100) due to its larger sensor. Moreover, the S1R II is a somewhat more recent model (by 1 year and 11 months) than the R100, and its sensor might 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Panasonic S1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1R II for good quality output (200 dots per inch) amounts to 40.7 x 27.1 inches or 103.4 x 68.9 cm, for very good quality (250 dpi) 32.6 x 21.7 inches or 82.7 x 55.1 cm, and for excellent quality (300 dpi) 27.1 x 18.1 inches or 69 x 45.9 cm. The corresponding values for the Canon R100 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

Unlike the R100, the S1R II has the capacity to capture high quality composite images (177MP) 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 R100 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DC-S1R II are ISO 80 to ISO 51200, with the possibility to increase the ISO range to 40-102400.

In terms of underlying technology, the R100 is build around a CMOS sensor, while the S1R II uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

R100 versus S1R II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the S1R II provides a better video resolution than the R100. It can shoot movie footage at 8K/30p, while the Canon is limited to 4k/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the S1R II offers a substantially higher resolution than the one in the R100 (5760k vs 2360k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The R100 has one, while the S1R II does not. While the built-in flash of the R100 is not very powerful, it can at times be useful as a fill-in light.

The S1R II 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 R100 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon R100 and the Panasonic S1R II 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.

The R100 writes its imaging data to SDXC cards, while the S1R II uses CFexpress (type B) or SDXC cards. The S1R II features dual card slots, which can be very useful in case a memory card fails. In contrast, the R100 only has one slot. The S1R II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the R100 can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

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 R100 and Panasonic Lumix DC-S1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1R II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The R100 lacks such a headphone port.

Studio photographers will appreciate that the Panasonic S1R II (unlike the R100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R100 and the S1R II are recent models that are part of the current product line-up. The S1R II replaced the earlier Panasonic S1R, while the R100 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.

Review summary

So how do things add up? Which of the two cameras – the Canon R100 or the Panasonic S1R II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the S1R II is the clear winner of the contest (26 : 6 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 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.

R100 06:26 S1R II

How about other alternatives? Do the specifications of the Canon R100 and the Panasonic S1R II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R100 or the S1R II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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.
