Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax 645Z and the Ricoh WG-6? 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 Pentax 645Z and the Ricoh WG-6. 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 measures are rounded to the nearest millimeter.

The WG-6 can be obtained in two different colors (black, orange), while the 645Z is only available in black.

Compare 645Z versus WG-6 top
Comparison 645Z or WG-6 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh WG-6 is considerably smaller (57 percent) than the Pentax 645Z. 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. More than that, the WG-6 is water-proof up to 20m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the WG-6 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.

The power pack in the WG-6 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The WG-6 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Pentax 645Z features a medium format sensor and the Ricoh WG-6 a 1/2.3-inch sensor. The sensor area in the WG-6 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 Ricoh WG-6 sensor measures

With 51.1MP, the 645Z offers a higher resolution than the WG-6 (20.2MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 1.18μm for the WG-6) due to its larger sensor. However, the WG-6 is a much more recent model (by 4 years and 10 months) than the 645Z, 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 Ricoh WG-6 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 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 Ricoh WG-6 are ISO 125 to ISO 6400 (no boost).

645Z versus WG-6 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 645Z has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the WG-6 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Pentax 645Z and Ricoh WG-6 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 645Z, but is missing on the WG-6 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 Pentax 645Z and the Ricoh WG-6 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 645Z and the WG-6 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 WG-6 only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the WG-6 cannot take advantage of Ultra High Speed SD cards.

It is notable that the 645Z has a hotshoe, while the WG-6 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Pentax 645Z (unlike the WG-6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the WG-6 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 645Z and the WG-6 are recent models that are part of the current product line-up. The 645Z replaced the earlier Pentax 645D, while the WG-6 followed on from the Ricoh WG-5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Ricoh websites.

Review summary

So what conclusions can be drawn? Is the Pentax 645Z better than the Ricoh WG-6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Pentax 645Z:

  • More detail: Offers more megapixels (51.1 vs 20.2MP) with a 59% higher linear resolution.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • 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 an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (3 vs 1 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (650 versus 340) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • 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 heavily discounted: Has been available for much longer (launched in April 2014).

ilogo

Advantages of the Ricoh WG-6:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
  • Ready to shoot: Comes with an integrated lens, while the 645Z requires a separate lens.
  • More compact: Is smaller (118x66mm 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).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 20m).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 4 years and 10 months of technical progress since the 645Z launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 645Z is the clear winner of the match-up (18 : 10 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

645Z 18:10 WG-6

How about other alternatives? Do the specifications of the Pentax 645Z and the Ricoh WG-6 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the 645Z and the WG-6 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], 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 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.
