Canon 1100D vs 1Ds

The Canon EOS 1100D (called Canon T3 in some regions) and the Canon EOS-1Ds are two digital cameras that were officially introduced, respectively, in February 2011 and September 2002. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (1100D) and a full frame (1Ds) sensor. The 1100D has a resolution of 12.2 megapixels, whereas the 1Ds provides 11 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 1100D and the Canon EOS-1Ds? 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 side-by-side display below illustrates the physical size and weight of the Canon 1100D and the Canon 1Ds. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1Ds is considerably larger (90 percent) than the Canon 1100D. Moreover, the 1Ds is substantially heavier (156 percent) than the 1100D. It is noteworthy in this context that the 1Ds is splash and dust-proof, while the 1100D 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 (1100D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1100D gets 700 shots out of its Canon LP-E10 battery, while the 1Ds can take 600 images on a single charge of its Canon NP-E3 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. In order to provide similar functionality for the 1100D, there are third party battery grips available as optional accessories (see here on ebay).

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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1100D 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.

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. 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 1100D features an APS-C sensor and the Canon 1Ds a full frame sensor. The sensor area in the 1Ds is 165 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the 1100D 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 Canon 1100D offers a higher resolution of 12.2 megapixels, compared with 11 MP of the Canon 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 5.15μm versus 8.83μm for the 1Ds). However, it should be noted that the 1100D is much more recent (by 8 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 1100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1100D for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 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 1100D has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Canon EOS-1Ds are ISO 100 to ISO 1250, with the possibility to increase the ISO range to 50-1250.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 can also record movies. The 1100D indeed provides movie recording capabilities, while the 1Ds does not. The highest resolution format that the 1100D can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1100D and the 1Ds 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 1100D (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 1100D, the Canon 1Ds, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 1100D has one, while the 1Ds does not. While the built-in flash of the 1100D is not very powerful, it can at times be useful as a fill-in light.

The 1100D writes its imaging data to SDXC cards, while the 1Ds uses Compact Flash cards.

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 1100D and Canon EOS-1Ds and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds (unlike the 1100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1100D and the 1Ds have been discontinued, but can regularly be found used on ebay. The 1Ds was replaced by the Canon 1Ds Mark II, while the 1100D was followed by the Canon 1200D. Further information on the features and operation of the 1100D and 1Ds can be found, respectively, in the Canon 1100D Manual (free pdf) or the online Canon 1Ds Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon 1100D or the Canon 1Ds – 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 1100D:

• More detail: Offers more megapixels (12.2 vs 11MP) with a 5% higher linear resolution.
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC).
• Broader imaging potential: Can record not only still images but also 720/30p movies.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
• More compact: Is smaller (130x100mm vs 156x158mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 770g or 61 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (700 versus 600) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (95 percent cheaper at launch).
• More modern: Reflects 8 years and 4 months of technical progress since the 1Ds launch.

Arguments in favor of the Canon EOS-1Ds:

• Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
• 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 a control panel on top to check 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 splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been around for much longer (launched in September 2002).

If the count of individual advantages (bullet points above) is taken as a guide, the 1100D emerges as the winner of the contest (11 : 9 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 1100D and the Canon 1Ds 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 1100D and the 1Ds in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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