Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax 645Z and the Sony Alpha NEX-3N? 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: Pentax 645Z vs Sony NEX-3N
An illustration of the physical size and weight of the Pentax 645Z and the Sony NEX-3N is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The NEX-3N can be obtained in two different colors (black, white), while the 645Z is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-3N is considerably smaller (63 percent) than the Pentax 645Z. Moreover, the NEX-3N is substantially lighter (83 percent) than the 645Z. It is worth mentioning in this context that the 645Z is splash and dust resistant, while the NEX-3N 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.

Any camera decision will naturally be influenced heavily by the price. 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 NEX-3N was launched at a markedly lower price (by 94 percent) than the 645Z, 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.
Sensor comparison: Pentax 645Z vs Sony NEX-3N
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 Sony NEX-3N an APS-C sensor. The sensor area in the NEX-3N is 75 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the 645Z has a native 4:3 aspect ratio, while the one in the NEX-3N offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 51.1MP, the 645Z offers a higher resolution than the NEX-3N (16MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 4.78μm for the NEX-3N) due to its larger sensor. Moreover, the 645Z is a somewhat more recent model (by 1 year and 1 month) than the NEX-3N, and its sensor might 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 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 inch or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inch or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inch or 69.9 x 52.4 cm. The corresponding values for the Sony NEX-3N are 24.6 x 16.3 inch or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inch or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inch or 41.6 x 27.6 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 Sony Alpha NEX-3N are ISO 200 to ISO 16000 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the 645Z provides substantially higher image quality than the NEX-3N, with an overall score that is 27 points higher. This advantage is based on 3.2 bits higher color depth, 2.2 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60i).
Feature comparison: Pentax 645Z vs Sony NEX-3N
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 NEX-3N relies on live view and the rear LCD for framing. That said, the NEX-3N can be equipped with an optional viewfinder – the FDA-SV1. The following table reports on some other key feature differences and similarities of the Pentax 645Z, the Sony NEX-3N, and comparable cameras.

One feature that is present on the 645Z, but is missing on the NEX-3N 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 NEX-3N has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 645Z does not have a selfie-screen.
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.
The 645Z writes its imaging data to SDXC cards, while the NEX-3N uses SDXC or Memory Stick PRO Duo cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the NEX-3N only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3N cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison: Pentax 645Z vs Sony NEX-3N
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 Pentax 645Z and Sony Alpha NEX-3N 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 hotshoe, while the NEX-3N 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 NEX-3N) 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 NEX-3N has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the NEX-3N was succeeded by the Sony A5000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Sony websites.

If the number of relative strengths (bullet points above) is taken as a guide, the 645Z is the clear winner of the match-up (20 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.
How about other alternatives? Do the specifications of the Pentax 645Z and the Sony NEX-3N 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 645Z or the NEX-3N. 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: Pentax 645Z vs Sony NEX-3N
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

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.
