Canon 1Ds vs T7
The Canon EOS-1Ds and the Canon EOS Rebel T7 (labelled Canon 2000D in some countries) are two digital cameras that were officially introduced, respectively, in September 2002 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (T7) sensor. The 1Ds has a resolution of 11 megapixels, whereas the T7 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 T7? 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.
The physical size and weight of the Canon 1Ds and the Canon T7 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 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 T7 is considerably smaller (47 percent) than the Canon 1Ds. Moreover, the T7 is substantially lighter (62 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the T7 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 (T7). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 battery, while the T7 can take 500 images on a single charge of its LP-E10 power pack. 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 T7 was launched at a markedly lower price (by 95 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.
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1Ds features a full frame sensor and the Canon T7 an APS-C sensor. The sensor area in the T7 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 T7 uses a more advanced image processing engine (DIGIC 4+) than the 1Ds (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the T7 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 T7 is much more recent (by 15 years and 5 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 T7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inches or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inches or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inches or 34.4 x 22.9 cm for excellent quality prints.
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 T7 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The T7 indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the T7 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds and the T7 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 T7 (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 0.50x), 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 T7, and comparable cameras.

One feature that is present on the 1Ds, but is missing on the T7 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 1Ds writes its imaging data to Compact Flash cards, while the T7 uses SDXC cards.
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 T7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7 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 provide wifi capability.
Studio photographers will appreciate that the Canon 1Ds (unlike the T7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The T7 is a recent model that features in the current product line-up of Canon. In contrast, the 1Ds has been discontinued (but 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.
So what is the bottom line? Is the Canon 1Ds better than the Canon T7 or vice versa? 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 0.50x).

If the number of relative strengths (bullet points above) is taken as a guide, the T7 emerges as the winner of the match-up (12 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 1Ds and the Canon T7 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 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 1Ds or the T7 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
