Nikon D700 vs Pentax 645Z

The Nikon D700 and the Pentax 645Z are two digital cameras that were officially introduced, respectively, in July 2008 and April 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D700) and a medium format (645Z) sensor. The Nikon has a resolution of 12.1 megapixels, whereas the Pentax provides 51.1 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 Nikon D700 and the Pentax 645Z? 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

An illustration of the physical size and weight of the Nikon D700 and the Pentax 645Z is provided 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 measures are rounded to the nearest millimeter.

Compare D700 versus 645Z top
Comparison D700 or 645Z rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D700 and the Pentax 645Z are of equal size. However, the 645Z is substantially heavier (44 percent) than the D700. 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 D700 gets 1000 shots out of its EN-EL3e battery, while the 645Z can take 650 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. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 D700 was launched at a markedly lower price (by 65 percent) than the 645Z, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D700 features a full frame sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 67 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 D700 has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.

Nikon D700 and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the D700 (12.1MP), but the 645Z has smaller individual pixels (pixel pitch of 5.30μm versus 8.43μm for the D700). Yet, the 645Z is a much more recent model (by 5 years and 9 months) than the D700, 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 645Z has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax 645Z implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645Z for good quality output (200 dots per inch) amounts to 41.3 x 31 inches or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inches or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inches or 69.9 x 52.4 cm. The corresponding values for the Nikon D700 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 D700 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 645Z are ISO 100 to ISO 204800 (no boost).

D700 versus 645Z MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under consideration, the 645Z offers substantially better image quality than the D700 (overall score 21 points higher). The advantage is based on 2.5 bits higher color depth, 2.5 EV in additional dynamic range, and 1 stops in additional 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 cannot only take still pictures, but also record videos. The 645Z indeed provides for movie recording, while the D700 does not. The highest resolution format that the 645Z can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D700 and the 645Z 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 645Z offers a wider field of view (98%) than the one in the D700 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 645Z has a higher magnification (0.78x vs 0.72x), 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 Nikon D700, the Pentax 645Z, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D700 has one, while the 645Z does not. While the built-in flash of the D700 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D700 and the Pentax 645Z 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 D700 writes its imaging data to Compact Flash cards, while the 645Z uses SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the D700 only has one slot.

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 D700 and Pentax 645Z 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.

The 645Z is a recent model that features in the current product line-up of Pentax. In contrast, the D700 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D700 was succeeded by the Nikon D800. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Pentax websites.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D700 and the Pentax 645Z? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Nikon D700:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 476g or 31 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (1000 versus 650) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 July 2008).

ilogo

Arguments in favor of the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 12.1MP), which boosts linear resolution by 102%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (21 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • 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 (98% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.72x).
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 922k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 5 years and 9 months of technical progress since the D700 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (15 : 8 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.

D700 08:15 645Z

How about other alternatives? Do the specifications of the Nikon D700 and the Pentax 645Z 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 says little about, for example, the shooting experience and imaging performance of the D700 and the 645Z in practical situations. 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.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
