Canon 1000D vs Pentax K-3
The Canon EOS 1000D (called Canon XS in some regions) and the Pentax K-3 are two digital cameras that were announced, respectively, in June 2008 and October 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Pentax provides 24.1 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 1000D and the Pentax K-3? 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 1000D and the Pentax K-3 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 dimensions are rounded to the nearest millimeter.
The K-3 can be obtained in two different colors (black, silver), while the 1000D is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 is notably larger (6 percent) than the Canon 1000D. Moreover, the K-3 is substantially heavier (59 percent) than the 1000D. It is noteworthy in this context that the K-3 is splash and dust-proof, while the 1000D 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1000D was launched at a markedly lower price (by 65 percent) than the K-3, 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.
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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-3 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (1000D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24.1MP, the K-3 offers a higher resolution than the 1000D (10.1MP), but the K-3 has smaller individual pixels (pixel pitch of 3.90μm versus 5.71μm for the 1000D). Yet, the K-3 is a much more recent model (by 5 years and 3 months) than the 1000D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-3 for good quality output (200 dots per inch) amounts to 30.1 x 20 inch or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inch or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inch or 50.9 x 33.9 cm. The corresponding values for the Canon 1000D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 1000D has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-1600. The corresponding ISO settings for the Pentax K-3 are ISO 100 to ISO 51200 (no boost).
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 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 cannot only take still pictures, but also record videos. The K-3 indeed provides for movie recording, while the 1000D does not. The highest resolution format that the K-3 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The 1000D and the K-3 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 K-3 offers a wider field of view (100%) than the one in the 1000D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-3 has a higher magnification (0.63x vs 0.51x), 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 1000D, the Pentax K-3, and comparable cameras.

One feature that differentiates the K-3 and the 1000D is in-body image stabilization (IBIS). The K-3 reduces the risk of handshake-induced blur with all attached lenses, while the 1000D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
The Pentax K-3 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 1000D writes its imaging data to SDHC cards, while the K-3 uses SDXC cards. The K-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1000D only has one slot. The K-3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1000D cannot take advantage of Ultra High Speed SD 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 1000D and Pentax K-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Pentax K-3 (unlike the 1000D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1000D and the K-3 have been discontinued, but can regularly be found used on eBay. The 1000D was replaced by the Canon 1100D, while the K-3 was followed by the Pentax K-3 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 conclusions can be drawn? Which of the two cameras – the Canon 1000D or the Pentax K-3 – 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 1000D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Less heavy: Is lighter (by 298g or 37 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in June 2008).
Reasons to prefer the Pentax K-3:
- More detail: Has more megapixels (24.1 vs 10.1MP), which boosts linear resolution by 55%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- 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 (0.63x vs 0.51x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (8.3 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (560 versus 500) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- 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.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 5 years and 3 months of technical progress since the 1000D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the K-3 is the clear winner of the contest (19 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 1000D and the Pentax K-3 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 1000D or the K-3 perform in practice. 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
