Leica T vs Pentax 645D

The Leica T (Typ 701) and the Pentax 645D are two digital cameras that were revealed to the public, respectively, in April 2014 and March 2010. The T Typ 701 is a mirrorless interchangeable lens camera, while the 645D is a DSLR. The cameras are based on an APS-C (T Typ 701) and a medium format (645D) sensor. The Leica has a resolution of 16.2 megapixels, whereas the Pentax provides 39.5 MP.

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

Body comparison

The side-by-side display below illustrates the physical size and weight of the Leica T and the Pentax 645D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The T Typ 701 can be obtained in two different colors (black, silver), while the 645D is only available in black.

Size Leica T vs Pentax 645D
Compare T Typ 701 versus 645D top
Comparison T Typ 701 or 645D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645D is considerably larger (97 percent) than the Leica T. Moreover, the 645D is substantially heavier (285 percent) than the T Typ 701. It is noteworthy in this context that the 645D is splash and dust-proof, while the T Typ 701 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 T Typ 701 gets 400 shots out of its Leica BP-DC13 battery, while the 645D can take 800 images on a single charge of its Pentax D-LI90 power pack. The power pack in the T Typ 701 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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.

Any camera decision will obviously take relative prices into account. 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 T Typ 701 was launched at a markedly lower price (by 82 percent) than the 645D, which puts it into a different market segment. 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 size of the sensor inside a digital camera is one of the key determinants 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. 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 T features an APS-C sensor and the Pentax 645D a medium format sensor. The sensor area in the 645D is 291 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.79. The sensor in the T Typ 701 has a native 3:2 aspect ratio, while the one in the 645D offers a 4:3 aspect.

Leica T and Pentax 645D sensor measures

With 39.5MP, the 645D offers a higher resolution than the T Typ 701 (16.2MP), but the 645D nevertheless has larger individual pixels (pixel pitch of 6.06μm versus 4.79μm for the T Typ 701) due to its larger sensor. However, the T Typ 701 is a much more recent model (by 4 years and 1 month) than the 645D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 645D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645D for good quality output (200 dots per inch) amounts to 36.3 x 27.2 inches or 92.3 x 69.1 cm, for very good quality (250 dpi) 29.1 x 21.8 inches or 73.8 x 55.3 cm, and for excellent quality (300 dpi) 24.2 x 18.1 inches or 61.5 x 46.1 cm. The corresponding values for the Leica T are 24.7 x 16.4 inches or 62.8 x 41.6 cm for good quality, 19.8 x 13.1 inches or 50.2 x 33.3 cm for very good quality, and 16.5 x 10.9 inches or 41.9 x 27.8 cm for excellent quality prints.

The Leica T (Typ 701) has a native sensitivity range from ISO 100 to ISO 12500. The corresponding ISO settings for the Pentax 645D are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the T Typ 701 is build around a CMOS sensor, while the 645D uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

T Typ 701 versus 645D MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the 645D has a markedly higher DXO score than the T Typ 701 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1.6 bits higher color depth, 0.1 EV of lower dynamic range, and 0.2 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 645D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the T Typ 701 relies on live view and the rear LCD for framing. That said, the T Typ 701 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The table below summarizes some of the other core capabilities of the Leica T and Pentax 645D in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The T Typ 701 has one, while the 645D does not. While the built-in flash of the T Typ 701 is not very powerful, it can at times be useful as a fill-in light.

The Pentax 645D 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 T Typ 701 and the 645D write their files to SDXC cards. The 645D features dual card slots, which can be very useful in case a memory card fails. In contrast, the T Typ 701 only has one slot.

It is notable that the T Typ 701 offers wifi support, while the 645D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Pentax 645D (unlike the T Typ 701) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the T Typ 701 and the 645D have been discontinued, but can regularly be found used on ebay. The 645D was replaced by the Pentax 645Z, while the T Typ 701 was followed by the Leica TL. Further information on the features and operation of the T Typ 701 and 645D can be found, respectively, in the Leica T Manual (free pdf) or the online Pentax 645D Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica T or the Pentax 645D – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Leica T (Typ 701):

  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Larger screen: Has a bigger rear LCD (3.7" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (5 vs 1.1 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (134x69mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1096g or 74 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
  • More modern: Reflects 4 years and 1 month of technical progress since the 645D launch.

ilogo

Reasons to prefer the Pentax 645D:

  • More detail: Has more megapixels (39.5 vs 16.2MP), which boosts linear resolution by 53%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • 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.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (800 versus 400) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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.
  • More heavily discounted: Has been around for much longer (launched in March 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the T Typ 701 emerges as the winner of the contest (14 : 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.

T Typ 701 14:11 645D

How about other alternatives? Do the specifications of the Leica T and the Pentax 645D 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 incomplete and does no justice, for example, to the way the T Typ 701 or the 645D perform in practice. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
