Canon 1Ds Mark II vs T7

The Canon EOS-1Ds Mark II and the Canon EOS Rebel T7 (labelled Canon 2000D in some countries) are two digital cameras that were officially introduced, respectively, in September 2004 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark II) and an APS-C (T7) sensor. The 1Ds Mark II has a resolution of 16.6 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 Mark II 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.

Body comparison

The physical size and weight of the Canon 1Ds Mark II 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 Mark II. Moreover, the T7 is substantially lighter (61 percent) than the 1Ds Mark II. It is worth mentioning in this context that the 1Ds Mark II 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 Mark II) 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 Mark II gets 1200 shots out of its Canon NP-E3 battery, while the T7 can take 500 images on a single charge of its Canon LP-E10 power pack. As can be seen in the images above, the 1Ds Mark II has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 T7 was launched at a markedly lower price (by 94 percent) than the 1Ds Mark II, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark II features a full frame sensor and the Canon T7 an APS-C sensor. The sensor area in the T7 is 62 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 Mark II (DIGIC II), 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 16.6 MP of the 1Ds Mark II. 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 7.21μm for the 1Ds Mark II). However, it should be noted that the T7 is much more recent (by 13 years and 5 months) than the 1Ds Mark II, 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 Mark II are 25 x 16.6 inches or 63.4 x 42.3 cm for good quality, 20 x 13.3 inches or 50.7 x 33.8 cm for very good quality, and 16.6 x 11.1 inches or 42.3 x 28.2 cm for excellent quality prints.

The Canon EOS-1Ds Mark II has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. 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.

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.

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 cannot only take still pictures, but also record videos. The T7 indeed provides for movie recording, while the 1Ds Mark II does not. The highest resolution format that the T7 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds Mark II 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 Mark II 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 Mark II 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 Mark II, the Canon T7, and comparable cameras.

One feature that is present on the 1Ds Mark II, 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 Mark II writes its imaging data to Compact Flash or SDHC cards, while the T7 uses SDXC cards. The 1Ds Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the T7 only has one slot.

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-1Ds Mark II 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 Mark II does not provide wifi capability.

Studio photographers will appreciate that the Canon 1Ds Mark II (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 Mark II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1Ds Mark II was succeeded by the Canon 1Ds Mark III. Further information on the features and operation of the 1Ds Mark II and T7 can be found, respectively, in the Canon 1Ds Mark II Manual (free pdf) or the online Canon T7 Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon 1Ds Mark II or the Canon T7 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS-1Ds Mark II:

• 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).
• 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.
• Faster burst: Shoots at higher frequency (4 vs 3 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 (1200 versus 500) on a single battery charge.
• 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.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in September 2004).

Arguments in favor of the Canon EOS Rebel T7:

• More detail: Has more megapixels (24 vs 16.6MP), which boosts linear resolution by 20%.
• Better jpgs: Has a more modern image processing engine (DIGIC 4+ vs DIGIC II).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• 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 (920k vs 230k dots).
• More compact: Is smaller (129x101mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 740g or 61 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.
• More affordable: Was introduced into a lower priced category (94 percent cheaper at launch).
• More modern: Reflects 13 years and 5 months of technical progress since the 1Ds Mark II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the T7 comes out slightly ahead of the 1Ds Mark II (12 : 11 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 Mark II 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 1Ds Mark II and the T7 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
