Canon D30 versus Pentax K-3 II

The Canon EOS-D30 and the Pentax K-3 II are two digital cameras that were officially introduced, respectively, in May 2000 and April 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 3.1 megapixel, whereas the Pentax provides 24.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon D30 vs Pentax K-3 II

The physical size and weight of the Canon D30 and the Pentax K-3 II 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 measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the Canon D30 – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 II is notably smaller (18 percent) than the Canon D30. However, the K-3 II is markedly heavier (7 percent) than the Canon D30. It is noteworthy in this context that the K-3 II is splash and dust-proof, while the Canon D30 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 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 Canon D30 gets 540 shots out of its BP-511 battery, while the K-3 II can take 720 images on a single charge of its D-LI90 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. 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-3 II was launched at a markedly lower price (by 63 percent) than the Canon D30, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon D30 vs Pentax K-3 II

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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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 II is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (Canon D30) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon D30 and Pentax K-3 II sensor measures

With 24.1MP, the K-3 II offers a higher resolution than the Canon D30 (3.1MP), but the K-3 II has smaller individual pixels (pixel pitch of 3.90μm versus 10.29μm for the Canon D30). Yet, the K-3 II is a much more recent model (by 14 years and 11 months) than the Canon D30, 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 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the Canon D30, the K-3 II has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The K-3 II indeed provides for movie recording, while the Canon D30 does not. The highest resolution format that the K-3 II can use is 1080/60i.

 

Feature comparison: Canon D30 vs Pentax K-3 II

Apart from body and sensor, cameras can and do differ across a variety of features. The Canon D30 and the K-3 II 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 table below summarizes some of the other core capabilities of the Canon D30 and Pentax K-3 II in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The Canon D30 has one, while the K-3 II does not. While the build-in flash of the Canon D30 is not very powerful, it can at times be useful as a fill-in light.

The Canon D30 writes its imaging data to Compact Flash cards, while the K-3 II uses SDXC cards. The K-3 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon D30 only has one slot.

  • Larger screen: Has a bigger rear LCD (3.2" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 114k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (8.3 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 150x107mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (720 versus 540) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 1.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More modern: Reflects 14 years and 11 months of technical progress since the Canon D30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the K-3 II is the clear winner of the contest (16 : 3 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.

Canon D30 03:16 K-3 II

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 Canon D30 or the K-3 II handle or perform in practice. 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
