Nikon D3 vs Pentax 645D
The Nikon D3 and the Pentax 645D are two professional cameras that were announced, respectively, in August 2007 and March 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D3) and a medium format (645D) sensor. The Nikon has a resolution of 12.1 megapixels, whereas the Pentax provides 39.5 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 Nikon D3 and the Pentax 645D? 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
The side-by-side display below illustrates the physical size and weight of the Nikon D3 and the Pentax 645D. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645D is notably smaller (27 percent) than the Nikon D3. However, the 645D is markedly heavier (14 percent) than the D3. 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 D3 gets 4300 shots out of its Nikon EN-EL4a battery, while the 645D can take 800 images on a single charge of its Pentax D-LI90 power pack. As can be seen in the images above, the D3 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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 D3 was launched at a markedly lower price (by 50 percent) than the 645D, 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
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D3 features a full frame sensor and the Pentax 645D a medium format sensor. The sensor area in the 645D is 69 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.79. The sensor in the D3 has a native 3:2 aspect ratio, while the one in the 645D offers a 4:3 aspect.
With 39.5MP, the 645D offers a higher resolution than the D3 (12.1MP), but the 645D has smaller individual pixels (pixel pitch of 6.06μm versus 8.43μm for the D3). Yet, the 645D is a much more recent model (by 2 years and 6 months) than the D3, 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 645D has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax 645D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645D for good quality output (200 dots per inch) amounts to 36.3 x 27.2 inches or 92.3 x 69.1 cm, for very good quality (250 dpi) 29.1 x 21.8 inches or 73.8 x 55.3 cm, and for excellent quality (300 dpi) 24.2 x 18.1 inches or 61.5 x 46.1 cm. The corresponding values for the Nikon D3 are 21.3 x 14.2 inches or 54.1 x 36 cm for good quality, 17 x 11.3 inches or 43.2 x 28.8 cm for very good quality, and 14.2 x 9.4 inches or 36 x 24 cm for excellent quality prints.
The Nikon D3 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Pentax 645D are ISO 100 to ISO 1600 (no boost).
In terms of underlying technology, the D3 is build around a CMOS sensor, while the 645D uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance.

Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The D3 and the 645D 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 D3 offers a wider field of view (100%) than the one in the 645D (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 645D has a higher magnification (0.78x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3 and Pentax 645D in connection with corresponding information for a sample of similar cameras.

The Nikon D3 and the Pentax 645D both have 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 D3 writes its imaging data to Compact Flash cards, while the 645D uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
Connectivity comparison
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 Nikon D3 and Pentax 645D 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 D3 and the 645D have been discontinued, but can regularly be found used on ebay. The D3 was replaced by the Nikon D4, while the 645D was followed by the Pentax 645Z. Further information on the features and operation of the D3 and 645D can be found, respectively, in the Nikon D3 Manual (free pdf) or the online Pentax 645D Manual.
Review summary
So how do things add up? Is there a clear favorite between the Nikon D3 and the Pentax 645D? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D3:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (11 vs 1.1 flaps/sec) to capture the decisive moment.
- Less heavy: Is lighter (by 180g or 12 percent) and hence easier to carry around.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (4300 versus 800) on a single battery charge.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2007).
Advantages of the Pentax 645D:
- More detail: Has more megapixels (39.5 vs 12.1MP), which boosts linear resolution by 78%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.70x).
- More compact: Is smaller (156x117mm vs 160x157mm) and will fit more readily into a bag.
- More modern: Reflects 2 years and 6 months of technical progress since the D3 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the D3 is the clear winner of the match-up (10 : 6 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 Nikon D3 and the Pentax 645D 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 D3 or the 645D 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
