Panasonic G10 vs Pentax 645Z

The Panasonic Lumix DMC-G10 and the Pentax 645Z are two digital cameras that were announced, respectively, in March 2010 and April 2014. The G10 is a mirrorless interchangeable lens camera, while the 645Z is a DSLR. The cameras are based on a Four Thirds (G10) and a medium format (645Z) sensor. The Panasonic has a resolution of 12 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 Panasonic Lumix DMC-G10 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

The side-by-side display below illustrates the physical size and weight of the Panasonic G10 and the Pentax 645Z. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Panasonic G10 vs Pentax 645Z
Compare G10 versus 645Z top
Comparison G10 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 (75 percent) than the Panasonic G10. Moreover, the 645Z is substantially heavier (299 percent) than the G10. It is noteworthy in this context that the 645Z is splash and dust-proof, while the G10 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 G10 gets 380 shots out of its DMW-BLB13 battery, while the 645Z can take 650 images on a single charge of its D-LI90 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 G10 was launched at a markedly lower price (by 94 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 imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Panasonic G10 features a Four Thirds sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 539 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 0.79. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic G10 and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the G10 (12MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 4.33μm for the G10) due to its larger sensor. Moreover, the 645Z is a much more recent model (by 4 years and 1 month) than the G10, 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 Panasonic G10 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Panasonic Lumix DMC-G10 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).

G10 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 G10 (overall score 49 points higher). The advantage is based on 4.8 bits higher color depth, 4.6 EV in additional dynamic range, and 3.5 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 645Z provides a better video resolution than the G10. It can shoot movie footage at 1080/60i, while the Panasonic is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G10 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 viewfinder in the G10 offers a wider field of view (100%) than the one in the 645Z (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 645Z has a higher magnification (0.78x vs 0.52x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Panasonic G10 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 G10 has one, while the 645Z does not. While the built-in flash of the G10 is not very powerful, it can at times be useful as a fill-in light.

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 G10 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 G10 only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G10 cannot take advantage of Ultra High Speed SD cards.

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 Panasonic Lumix DMC-G10 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 G10 does not feature such a mic input.

Studio photographers will appreciate that the Pentax 645Z (unlike the G10) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The 645Z is a recent model that features in the current product line-up of Pentax. In contrast, the G10 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G10 was succeeded by the Panasonic G3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Pentax websites.

Review summary

So how do things add up? Which of the two cameras – the Panasonic G10 or the Pentax 645Z – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 4 years and 1 month of technical progress since the G10 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (23 : 9 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.

G10 09:23 645Z

How about other alternatives? Do the specifications of the Panasonic G10 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G10 or the 645Z. 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
