Canon 1Ds vs T7i

The Canon EOS-1Ds and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were announced, respectively, in September 2002 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (T7i) sensor. The 1Ds has a resolution of 11 megapixels, whereas the T7i provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds and the Canon EOS Rebel T7i? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 1Ds vs T7i

The physical size and weight of the Canon 1Ds and the Canon T7i are illustrated 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 dimensions are rounded to the nearest millimeter.

Size Canon 1Ds vs Canon T7i
Compare 1Ds versus T7i top
Comparison 1Ds or T7i rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T7i is considerably smaller (47 percent) than the Canon 1Ds. Moreover, the T7i is substantially lighter (58 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the T7i 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. A larger imaging sensor (as in the 1Ds) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T7i). You can compare the optics available in the Canon EF Lens Catalog.

As can be seen in the images above, the 1Ds 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 T7i, there are third party battery grips available as optional accessories (see here on eBay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T7i was launched at a markedly lower price (by 92 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.

 

Sensor comparison: Canon 1Ds vs T7i

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 1Ds features a full frame sensor and the Canon T7i an APS-C sensor. The sensor area in the T7i is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the T7i uses a more advanced image processing engine (DIGIC 7) than the 1Ds (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 1Ds and Canon T7i sensor measures

Despite having a smaller sensor, the T7i offers a higher resolution of 24 megapixels, compared with 11 MP of the 1Ds. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 8.83μm for the 1Ds). However, it should be noted that the T7i is much more recent (by 14 years and 4 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inch or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inch or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inch or 34.4 x 22.9 cm for excellent quality prints.

The T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Canon EOS Rebel T7i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

1Ds versus T7i 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 cannot only take still pictures, but also record videos. The T7i indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the T7i can use is 1080/60p.

 

Feature comparison: Canon 1Ds vs T7i

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds and the T7i 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 viewfinder in the 1Ds offers a wider field of view (100%) than the one in the T7i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds has a higher magnification (0.70x vs 0.51x), 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 1Ds, the Canon T7i, and comparable cameras.

One feature that is present on the 1Ds, but is missing on the T7i is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The T7i 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 1Ds does not have a selfie-screen.

The 1Ds writes its imaging data to Compact Flash cards, while the T7i uses SDXC cards.

 

Connectivity comparison: Canon 1Ds vs T7i

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-1Ds and Canon EOS Rebel T7i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1Ds does not offer wifi capability.

Studio photographers will appreciate that the Canon 1Ds (unlike the T7i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The T7i is a recent model that features in the current product line-up of Canon. 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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary: Canon 1Ds vs T7i

So what conclusions can be drawn? Which of the two cameras – the Canon 1Ds or the Canon T7i – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS-1Ds:

  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.51x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in September 2002).


Reasons to prefer the Canon EOS Rebel T7i:

  • More detail: Has more megapixels (24 vs 11MP), which boosts linear resolution by 48%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for quicker and more confident autofocus.
  • 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 (1040k vs 120k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 733g or 58 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
  • More modern: Reflects 14 years and 4 months of technical progress since the 1Ds launch.

If the count of relative strengths (bullet points above) is taken as a measure, the T7i is the clear winner of the contest (18 : 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.

1Ds 08:18 T7i

How about other alternatives? Do the specifications of the Canon 1Ds and the Canon T7i place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

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 1Ds or the T7i 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: Canon 1Ds vs T7i

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The above review scores should be interpreted 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
