Canon 1Ds vs Pentax K-5
The Canon EOS-1Ds and the Pentax K-5 are two digital cameras that were announced, respectively, in September 2002 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (K-5) sensor. The Canon has a resolution of 11 megapixels, whereas the Pentax provides 16.1 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 Pentax K-5? 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 side-by-side display below illustrates the physical size and weight of the Canon 1Ds and the Pentax K-5. 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 size 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 Pentax K-5 is considerably smaller (48 percent) than the Canon 1Ds. Moreover, the K-5 is substantially lighter (40 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 battery, while the K-5 can take 740 images on a single charge of its D-LI90 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 K-5, Pentax provides the D-BG4 vertical grip as an optional accessory (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 K-5 was launched at a markedly lower price (by 88 percent) than the 1Ds, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 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 Pentax K-5 an APS-C sensor. The sensor area in the K-5 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the K-5 offers a higher resolution of 16.1 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 4.81μm versus 8.83μm for the 1Ds). However, it should be noted that the K-5 is much more recent (by 7 years and 11 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 Pentax K-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-5 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 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 Pentax K-5 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 80-51200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 K-5 offers substantially better image quality than the 1Ds (overall score 19 points higher). The advantage is based on 1.9 bits higher color depth, 3.1 EV in additional dynamic range, and 0.3 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 K-5 indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the K-5 can use is 1080/25p.
Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the K-5 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 1Ds has a higher magnification than the one of the K-5 (0.70x vs 0.61x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1Ds and Pentax K-5 along with similar information for a selection of comparators.

One feature that differentiates the K-5 and the 1Ds is in-body image stabilization (IBIS). The K-5 reduces the risk of handshake-induced blur with all attached lenses, while the 1Ds offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The Pentax K-5 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 1Ds writes its imaging data to Compact Flash cards, while the K-5 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 Pentax K-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 1Ds and the K-5 have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, while the K-5 was followed by the Pentax K-5 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.
So what is the bottom line? Which of the two cameras – the Canon 1Ds or the Pentax K-5 – 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:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.61x).
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- More heavily discounted: Has been available for much longer (launched in September 2002).
Advantages of the Pentax K-5:
- More detail: Has more megapixels (16.1 vs 11MP), which boosts linear resolution by 21%.
- Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/25p 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 (921k vs 120k dots).
- Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (131x97mm vs 156x158mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 505g or 40 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (740 versus 600) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
- More modern: Reflects 7 years and 11 months of technical progress since the 1Ds launch.
If the number of relative strengths (bullet points above) is taken as a guide, the K-5 is the clear winner of the contest (16 : 3 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 and the Pentax K-5 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 and the K-5 in practical situations. 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 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.

The above review scores should be interpreted 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, please note that some of the review sites have changed their methodology and reporting over time.
