Body comparison

An illustration of the physical size and weight of the Panasonic LX7 and the Pentax 645Z is provided 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 dimensions are rounded to the nearest millimeter.

The LX7 can be obtained in two different colors (black, white), while the 645Z is only available in black.

Size Panasonic LX7 vs Pentax 645Z
Compare LX7 versus 645Z top
Comparison LX7 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 (142 percent) than the Panasonic LX7. It is noteworthy in this context that the 645Z is splash and dust-proof, while the LX7 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 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 LX7 gets 330 shots out of its Panasonic DMW-BCJ13 battery, while the 645Z can take 650 images on a single charge of its Pentax D-LI90 power pack.

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

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 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 LX7 was launched at a lower price than the 645Z, despite having a lens built in. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic LX7 features a 1/1.7-inch sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 3321 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 0.79. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Panasonic LX7 and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the LX7 (10MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 2.05μm for the LX7) due to its larger sensor. Moreover, the 645Z is a somewhat more recent model (by 1 year and 8 months) than the LX7, and its sensor might 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 Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Panasonic Lumix DMC-LX7 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. 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.

LX7 versus 645Z MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the 645Z offers substantially better image quality than the LX7 (overall score 51 points higher). The advantage is based on 5.3 bits higher color depth, 3 EV in additional dynamic range, and 4.9 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 645Z has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the LX7 relies on live view and the rear LCD for framing. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The adjacent table lists some of the other core features of the Panasonic LX7 and Pentax 645Z along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The LX7 has one, while the 645Z does not. While the built-in flash of the LX7 is not very powerful, it can at times be useful as a fill-in light.

The Panasonic LX7 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 LX7 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 LX7 only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the LX7 cannot take advantage of Ultra High Speed SD cards.

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 LX7 does not feature such a mic input.

Studio photographers will appreciate that the Pentax 645Z (unlike the LX7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the LX7 and the 645Z have been discontinued, but can regularly be found used on ebay. The LX7 was replaced by the Panasonic LX10, while the 645Z does not have a direct successor. Further information on the features and operation of the LX7 and 645Z can be found, respectively, in the Panasonic LX7 Manual (free pdf) or the online Pentax 645Z Manual.

Review summary

So how do things add up? Is there a clear favorite between the Panasonic LX7 and the Pentax 645Z? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Panasonic Lumix DMC-LX7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a built-in lens, while the 645Z requires a separate lens.
  • More compact: Is smaller (111x68mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the 645Z).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in July 2012).

ilogo

Advantages of the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 10MP), which boosts linear resolution by 126%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (51 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (5.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (4.9 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • 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 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (650 versus 330) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (20 : 11 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.

LX7 11:20 645Z

How about other alternatives? Do the specifications of the Panasonic LX7 and the Pentax 645Z place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings 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 remains incomplete and does no justice, for example, to the way the LX7 or the 645Z perform in practice. 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.

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

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
