Leica S3 vs Pentax Q

The Leica S3 and the Pentax Q are two digital cameras that were revealed to the public, respectively, in September 2018 and June 2011. The S3 is a DSLR, while the Pentax Q is a mirrorless interchangeable lens camera. The cameras are based on a medium format (S3) and a 1/2.3-inch (Pentax Q) sensor. The Leica has a resolution of 64 megapixels, whereas the Pentax provides 12 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 Leica S3 and the Pentax Q? 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

An illustration of the physical size and weight of the Leica S3 and the Pentax Q 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 measures are rounded to the nearest millimeter.

The Pentax Q can be obtained in two different colors (black, white), while the S3 is only available in black.

Compare S3 versus Pentax Q top
Comparison S3 or Pentax Q rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax Q is considerably smaller (71 percent) than the Leica S3. Moreover, the Pentax Q is substantially lighter (86 percent) than the S3. It is worth mentioning in this context that the S3 is splash and dust resistant, while the Pentax Q 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.

Note: Measurements and pricing do not include easily detachable parts, such as 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 Pentax Q was launched at a markedly lower price (by 97 percent) than the S3, 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica S3 features a medium format sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 98 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.8 and 5.6. The sensor in the S3 has a native 3:2 aspect ratio, while the one in the Pentax Q offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Leica S3 and Pentax Q sensor measures

With 64MP, the S3 offers a higher resolution than the Pentax Q (12MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the S3 is a much more recent model (by 7 years and 3 months) than the Pentax Q, 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 the S3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inch or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inch or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inch or 83 x 55.3 cm. The corresponding values for the Pentax Q are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.

The Leica S3 has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).

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, but the S3 provides a higher video resolution than the Pentax Q. It can shoot video footage at 4K/24p, while the Pentax is limited to 1080/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the S3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Pentax Q relies on live view and the rear LCD for framing. That said, the Pentax Q can be equipped with an optional viewfinder – the O-VF1. The following table reports on some other key feature differences and similarities of the Leica S3, the Pentax Q, and comparable cameras.

One feature that is present on the S3, but is missing on the Pentax Q 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 Q 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.

The S3 writes its imaging data to Compact Flash or SDXC cards, while the Pentax Q uses SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Pentax Q only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the Pentax Q 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 Leica S3 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 has a microphone port, which is missing on the Pentax Q. 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 Leica S3 (unlike the Pentax Q) 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 S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The S3 is a recent model that features in the current product line-up of Leica. In contrast, the Pentax Q has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the Pentax Q was succeeded by the Pentax Q10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Pentax websites.


Review summary

So how do things add up? Is the Leica S3 better than the Pentax Q or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Leica S3:

  • More detail: Offers more megapixels (64 vs 12MP) with a 136% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better video: Provides higher definition movie capture (4K/24p vs 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while 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.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (3 vs 1.5 flaps/sec) to capture the decisive moment.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • 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: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Reflects 7 years and 3 months of technical progress since the Pentax Q launch.

ilogo

Reasons to prefer the Pentax Q:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (98x57mm vs 160x120mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1080g or 86 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (97 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in June 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the S3 is the clear winner of the match-up (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 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.

S3 23:09 Pentax Q

How about other alternatives? Do the specifications of the Leica S3 and the Pentax Q place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the S3 and the Pentax Q in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
