Canon 1D Mark IV vs Pentax K-5
The Canon EOS-1D Mark IV and the Pentax K-5 are two digital cameras that were revealed to the public, respectively, in October 2009 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark IV) and an APS-C (K-5) sensor. The Canon has a resolution of 16 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-1D Mark IV 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 physical size and weight of the Canon 1D Mark IV and the Pentax K-5 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Pentax K-5 is considerably smaller (48 percent) than the Canon 1D Mark IV. Moreover, the K-5 is substantially lighter (38 percent) than the 1D Mark IV. 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 1D Mark IV gets 1500 shots out of its LP-E4 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 1D Mark IV 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).

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-5 was launched at a markedly lower price (by 78 percent) than the 1D Mark IV, 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Pentax K-5 an APS-C sensor. The sensor area in the K-5 is 28 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 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 slightly higher resolution of 16.1 megapixels, compared with 16 MP of the 1D Mark IV. 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 5.70μm for the 1D Mark IV). However, it should be noted that the K-5 is a somewhat more recent model (by 11 months) than the 1D Mark IV, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The Canon EOS-1D Mark IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 has a markedly higher DXO score than the 1D Mark IV (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 2.1 EV in additional dynamic range, and 0.2 stops of reduced low light sensitivity. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1D Mark IV provides a higher frame rate than the K-5. It can shoot video footage at 1080/30p, while the Pentax is limited to 1080/25p.
Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark IV 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 K-5 has a higher magnification than the one of the 1D Mark IV (0.61x vs 0.58x), 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 1D Mark IV, the Pentax K-5, and comparable cameras.

One feature that differentiates the K-5 and the 1D Mark IV is in-body image stabilization (IBIS). The K-5 reduces the risk of handshake-induced blur with all attached lenses, while the 1D Mark IV 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 1D Mark IV writes its imaging data to Compact Flash or SDHC cards, while the K-5 uses SDXC cards. The 1D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the K-5 only has one slot.
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-1D Mark IV 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 1D Mark IV and the K-5 have been discontinued, but can regularly be found used on eBay. The K-5 was replaced by the Pentax K-5 II, while the 1D Mark IV does not have a direct successor. 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 how do things add up? Which of the two cameras – the Canon 1D Mark IV or the Pentax K-5 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS-1D Mark IV:
- Better video: Provides higher movie framerates (1080/30p versus 1080/25p).
- Faster burst: Shoots at higher frequency (10 vs 7 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 (1500 versus 740) on a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been on the market for longer (launched in October 2009).
Reasons to prefer the Pentax K-5:
- Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.61x vs 0.58x).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (131x97mm vs 156x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 470g or 38 percent) and is thus easier to take along.
- 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 (78 percent cheaper at launch).
- More modern: Was introduced somewhat (11 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the K-5 is the clear winner of the contest (10 : 6 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 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.
How about other alternatives? Do the specifications of the Canon 1D Mark IV 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark IV or the K-5. 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.
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 (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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
