Pentax 645Z vs Leica V-LUX 2

The Pentax 645Z and the Leica V-LUX 2 are two digital cameras that were officially introduced, respectively, in April 2014 and September 2010. The 645Z is a DSLR, while the V-LUX 2 is a fixed lens compact. The cameras are based on a medium format (645Z) and a 1/2.3-inch (V-LUX 2) sensor. The Pentax has a resolution of 51.1 megapixels, whereas the Leica provides 14 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Pentax 645Z and the Leica V-LUX 2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Pentax 645Z vs Leica V-LUX 2
Compare 645Z versus V-LUX 2 top
Comparison 645Z or V-LUX 2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica V-LUX 2 is considerably smaller (46 percent) than the Pentax 645Z. It is worth mentioning in this context that the 645Z is splash and dust resistant, while the V-LUX 2 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the V-LUX 2 has a lens built in, whereas the 645Z is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the 645Z gets 650 shots out of its Pentax D-LI90 battery, while the V-LUX 2 can take 410 images on a single charge of its Leica BP-DC9 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 V-LUX 2 was launched at a lower price than the 645Z, despite having a lens built in. 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 size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Pentax 645Z features a medium format sensor and the Leica V-LUX 2 a 1/2.3-inch sensor. The sensor area in the V-LUX 2 is 98 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Pentax 645Z and Leica V-LUX 2 sensor measures

With 51.1MP, the 645Z offers a higher resolution than the V-LUX 2 (14MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 1.41μm for the V-LUX 2) due to its larger sensor. Moreover, the 645Z is a much more recent model (by 3 years and 6 months) than the V-LUX 2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 Leica V-LUX 2 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.

The Pentax 645Z has a native sensitivity range from ISO 100 to ISO 204800. The corresponding ISO settings for the Leica V-LUX 2 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-6400.

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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the V-LUX 2 has an electronic viewfinder (202k 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 following table reports on some other key feature differences and similarities of the Pentax 645Z, the Leica V-LUX 2, and comparable cameras.

One feature that is present on the 645Z, but is missing on the V-LUX 2 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 V-LUX 2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 645Z does not have a selfie-screen.

The Pentax 645Z 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.

Concerning the storage of imaging data, both the 645Z and the V-LUX 2 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 V-LUX 2 only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the V-LUX 2 cannot take advantage of Ultra High Speed SD cards.

It is notable that the 645Z has a microphone port, which is missing on the V-LUX 2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Pentax 645Z (unlike the V-LUX 2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 645Z and the V-LUX 2 have been discontinued, but can regularly be found used on ebay. The V-LUX 2 was replaced by the Leica V-LUX 3, while the 645Z does not have a direct successor. Further information on the features and operation of the 645Z and V-LUX 2 can be found, respectively, in the Pentax 645Z Manual (free pdf) or the online Leica V-LUX 2 Manual.

ilogo

Reasons to prefer the Leica V-LUX 2:

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 645Z requires a separate lens.
  • More compact: Is smaller (124x80mm vs 156x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 645Z).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in September 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the match-up (20 : 12 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

645Z 20:12 V-LUX 2

How about other alternatives? Do the specifications of the Pentax 645Z and the Leica V-LUX 2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the 645Z and the V-LUX 2 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
