Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon 1 V1 and the Pentax 645Z. 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.

Size Nikon 1 V1 vs Pentax 645Z
Compare V1 versus 645Z top
Comparison V1 or 645Z rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645Z is considerably larger (113 percent) than the Nikon 1 V1. Moreover, the 645Z is substantially heavier (305 percent) than the V1. It is noteworthy in this context that the 645Z is splash and dust-proof, while the V1 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.

Concerning battery life, the V1 gets 350 shots out of its Nikon EN-EL15 battery, while the 645Z can take 650 images on a single charge of its Pentax 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The V1 was launched at a markedly lower price (by 91 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. 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 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.

Of the two cameras under consideration, the Nikon 1 V1 features an one-inch sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 1139 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 0.79. The sensor in the V1 has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.

Nikon 1 V1 and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the V1 (10MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 3.41μm for the V1) due to its larger sensor. Moreover, the 645Z is a much more recent model (by 2 years and 6 months) than the V1, and its sensor will have benefitted from technological advances during this time that further 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 1 V1 are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.

The Nikon 1 V1 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

V1 versus 645Z MP

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. Of the two cameras under consideration, the 645Z offers substantially better image quality than the V1 (overall score 47 points higher). The advantage is based on 4.7 bits higher color depth, 3.7 EV in additional dynamic range, and 3.7 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. 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 (1080/60i).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the V1 has an electronic viewfinder (1440k dots), while the 645Z has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Nikon 1 V1 and Pentax 645Z in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the 645Z, but is missing on the V1 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the V1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon 1 V1 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.

Concerning the storage of imaging data, both the V1 and the 645Z write their files to SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the V1 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 1 V1 and Pentax 645Z and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 645Z has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The V1 does not feature such a mic input.

Studio photographers will appreciate that the Pentax 645Z (unlike the V1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the V1 and the 645Z have been discontinued, but can regularly be found used on ebay. The V1 was replaced by the Nikon 1 V2, while the 645Z does not have a direct successor. Further information on the features and operation of the V1 and 645Z can be found, respectively, in the Nikon 1 V1 Manual (free pdf) or the online Pentax 645Z Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon 1 V1 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 1 V1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (113x76mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1167g or 75 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2011).

ilogo

Advantages of the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 10MP), which boosts linear resolution by 122%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (47 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.7 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (3.7 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • 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 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Longer lasting: Gets more shots (650 versus 350) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • 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.
  • More modern: Reflects 2 years and 6 months of technical progress since the V1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (19 : 9 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.

V1 09:19 645Z

How about other alternatives? Do the specifications of the Nikon 1 V1 and the Pentax 645Z place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 V1 or the 645Z 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.

Expert reviews

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 (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.

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

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.
