Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark III and the Panasonic S1R. 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.

Size Canon 1D X Mark III vs Panasonic S1R
Compare 1DX Mark III versus S1R top
Comparison 1DX Mark III or S1R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1R is considerably smaller (38 percent) than the Canon 1D X Mark III. Moreover, the S1R is markedly lighter (29 percent) than the 1DX Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 1DX Mark III gets 2850 shots out of its Canon LP-E19 battery, while the S1R can take 380 images on a single charge of its Panasonic DMW-BLJ31 power pack. As can be seen in the images above, the 1DX Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the S1R, Panasonic provides the DMW-BGS1 vertical grip as an optional accessory (see here on ebay). The power pack in the S1R 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 S1R was launched at a markedly lower price (by 43 percent) than the 1DX Mark III, 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 sensor inside a digital camera is one of the key determinants 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.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1D X Mark III and Panasonic S1R sensor measures

While the two cameras under review share the same sensor size, the S1R offers a higher resolution of 46.7 megapixels, compared with 20 MP of the 1DX Mark III. This megapixels advantage translates into a 53 percent gain in linear resolution. On the other hand, these sensor specs imply that the S1R has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.30μm versus 6.57μm for the 1DX Mark III). Moreover, it should be noted, that the 1DX Mark III is a somewhat more recent model (by 11 months) than the S1R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the S1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic S1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1R for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Canon 1D X Mark III are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The 1DX Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the 1DX Mark III, the S1R has the capacity to capture high quality composite images (187MP) 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-1D X Mark III has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-819200. The corresponding ISO settings for the Panasonic Lumix DC-S1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

1DX Mark III versus S1R MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the S1R has a markedly higher DXO score than the 1DX Mark III (overall score 9 points higher), which will translate into better image quality. The advantage is based on 2.2 bits higher color depth, 0.4 EV of lower dynamic range, and 0.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the S1R has an electronic viewfinder (5760k dots), while the 1DX Mark III 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the S1R has a higher magnification than the one of the 1DX Mark III (0.78x vs 0.76x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 1D X Mark III, the Panasonic S1R, and comparable cameras.

One feature that differentiates the S1R and the 1DX Mark III is in-body image stabilization (IBIS). The S1R reduces the risk of handshake-induced blur with all attached lenses, while the 1DX Mark III offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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, the S1R is one of those camera that have an additional 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 1D X Mark III and the Panasonic S1R 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 1DX Mark III writes its imaging data to CFexpress (type B) cards, while the S1R uses SDXC or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the 1DX Mark III has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1DX Mark III and the S1R are recent models that are part of the current product line-up. The 1DX Mark III replaced the earlier Canon 1DX Mark II, while the S1R does not have a direct predecessor. Further information on the features and operation of the 1DX Mark III and S1R can be found, respectively, in the Canon 1D X Mark III Manual (free pdf) or the online Panasonic S1R Manual.

Review summary

So how do things add up? Is the Canon 1D X Mark III better than the Panasonic S1R or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon EOS-1D X Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster burst: Shoots at higher frequency (20 vs 9 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (2850 versus 380) on a single battery charge.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More modern: Is somewhat more recent (announced 11 months after the S1R).

ilogo

Arguments in favor of the Panasonic Lumix DC-S1R:

  • More detail: Has more megapixels (46.7 vs 20MP), which boosts linear resolution by 53%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.76x).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (149x110mm vs 158x168mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 424g or 29 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the S1R is the clear winner of the contest (17 : 8 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.

1DX Mark III 08:17 S1R

How about other alternatives? Do the specifications of the Canon 1D X Mark III and the Panasonic S1R place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 1DX Mark III or the S1R 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
