Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark IV and the Pentax Q? 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: Canon 1D Mark IV vs Pentax Q

The side-by-side display below illustrates the physical size and weight of the Canon 1D Mark IV and the Pentax Q. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The Pentax Q can be obtained in two different colors (black, white), while the 1D Mark IV is only available in black.

Compare 1D Mark IV versus Pentax Q top
Comparison 1D Mark IV or Pentax Q rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax Q is considerably smaller (77 percent) than the Canon 1D Mark IV. Moreover, the Pentax Q is substantially lighter (85 percent) than the 1D Mark IV. It is worth mentioning in this context that the 1D Mark IV is splash and dust resistant, while the Pentax Q 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. 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.

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.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will obviously take relative prices into account. 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 Pentax Q was launched at a markedly lower price (by 87 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.

 

Sensor comparison: Canon 1D Mark IV vs Pentax Q

The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 95 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 5.6. The sensor in the 1D Mark IV has a native 3:2 aspect ratio, while the one in the Pentax Q offers a 4:3 aspect.

Canon 1D Mark IV and Pentax Q sensor measures

With 16MP, the 1D Mark IV offers a higher resolution than the Pentax Q (12MP), but the 1D Mark IV nevertheless has larger individual pixels (pixel pitch of 5.70μm versus 1.53μm for the Pentax Q) due to its larger sensor. However, the Pentax Q is a somewhat more recent model (by 1 year and 8 months) than the 1D Mark IV, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 1D Mark IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1D Mark IV for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inch or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inch or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inch or 41.5 x 27.6 cm. The corresponding values for the Pentax Q are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.

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 Q are ISO 125 to ISO 6400 (no boost).

1D Mark IV versus Pentax Q MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the 1D Mark IV provides substantially higher image quality than the Pentax Q, with an overall score that is 27 points higher. This advantage is based on 2.6 bits higher color depth, 0.9 EV in additional dynamic range, and 2.8 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).

 

Feature comparison: Canon 1D Mark IV vs Pentax Q

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1D Mark IV has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Pentax Q relies on live view and the rear LCD for framing. That said, the Pentax Q can be equipped with an optional viewfinder – the O-VF1.

One feature that is present on the 1D Mark IV, but is missing on the Pentax Q 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 Pentax Q 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 Pentax Q 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 Pentax Q only has one slot.

It is notable that the 1D Mark IV has a microphone port, which is missing on the Pentax Q. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

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

Both the 1D Mark IV and the Pentax Q have been discontinued, but can regularly be found used on eBay. The Pentax Q was replaced by the Pentax Q10, 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.


Review summary: Canon 1D Mark IV vs Pentax Q

So what is the bottom line? Is the Canon 1D Mark IV better than the Pentax Q or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

ilogo

Arguments in favor of the Pentax Q:

  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (98x57mm vs 156x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1050g or 85 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (87 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 1D Mark IV is the clear winner of the match-up (17 : 8 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 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 Q place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark IV or the Pentax Q. 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: Canon 1D Mark IV vs Pentax Q

This is why hands-on reviews by experts are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
