Canon 1Ds versus Sony A7R III

The Canon EOS-1Ds and the Sony Alpha A7R III are two digital cameras that were announced, respectively, in September 2002 and October 2017. The 1Ds is a DSLR, while the A7R III is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The Canon has a resolution of 11 megapixel, whereas the Sony provides 42.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1Ds vs Sony A7R III

An illustration of the physical size and weight of the Canon 1Ds and the Sony A7R III is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1Ds – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R III is considerably smaller (50 percent) than the Canon 1Ds. Moreover, the A7R III is substantially lighter (49 percent) than the 1Ds. 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1Ds) and the Sony FE Lens Catalog (A7R III). Mirrorless cameras, such as the A7R III, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 battery, while the A7R III can take 650 images on a single charge of its NP-FZ100 power pack.

The price is, of course, an important factor in any camera decision. 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 A7R III was launched at a markedly lower price (by 64 percent) than the 1Ds, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 1Ds vs Sony A7R III

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A7R III is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1Ds and Sony A7R III sensor measures

With 42.2MP, the A7R III offers a higher resolution than the 1Ds (11MP), but the A7R III has smaller individual pixels (pixel pitch of 4.52μm versus 8.83μm for the 1Ds). Yet, the A7R III is a much more recent model (by 15 years and 1 month) than the 1Ds, and its sensor will 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 A7R III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the 1Ds, the A7R III 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).

1Ds versus A7R III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A7R III offers substantially better image quality than the 1Ds (overall score 37 points higher). The advantage is based on 4.2 bits higher color depth, 3.7 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A7R III indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the A7R III can use is 4K/30p.

 

Feature comparison: Canon 1Ds vs Sony A7R III

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R III has an electronic viewfinder (3686k dots), while the 1Ds 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 adjacent table lists some of the other core features of the Canon 1Ds and Sony A7R III along with similar information for a selection of comparators.

The A7R III is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1Ds has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1Ds was succeeded by the Canon 1Ds Mark II.

Review summary: Canon 1Ds vs Sony A7R III

So what conclusions can be drawn? Is there a clear favorite between the Canon 1Ds and the Sony A7R III? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Canon EOS-1Ds:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More heavily discounted: Has been available for much longer (launched in September 2002).

ilogo

Advantages of the Sony Alpha A7R III:

  • More detail: Has more megapixels (42.2 vs 11MP), which boosts linear resolution by 96%.
  • 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 substantially higher (37 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 120k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (127x96mm vs 156x157.6mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 615g or 49 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More modern: Reflects 15 years and 1 month of technical progress since the 1Ds launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R III is the clear winner of the contest (20 : 4 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.

1Ds 04:20 A7R III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1Ds and the A7R III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
