Nikon D3400 vs Pentax 645D

The Nikon D3400 and the Pentax 645D are two digital cameras that were officially introduced, respectively, in August 2016 and March 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D3400) and a medium format (645D) sensor. The Nikon has a resolution of 24 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.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3400 and the Pentax 645D? 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 physical size and weight of the Nikon D3400 and the Pentax 645D are illustrated 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 dimensions are rounded to the nearest millimeter.

The D3400 can be obtained in two different colors (black, red), while the 645D is only available in black.

Compare D3400 versus 645D top
Comparison D3400 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 (50 percent) than the Nikon D3400. Moreover, the 645D is substantially heavier (233 percent) than the D3400. It is noteworthy in this context that the 645D is splash and dust-proof, while the D3400 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 D3400 gets 1200 shots out of its EN-EL14a battery, while the 645D can take 800 images on a single charge of its D-LI90 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D3400 was launched at a markedly lower price (by 95 percent) than the 645D, 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 sensor inside a digital camera is one of the key determinants 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 Nikon D3400 features an APS-C sensor and the Pentax 645D a medium format sensor. The sensor area in the 645D is 296 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 D3400 has a native 3:2 aspect ratio, while the one in the 645D offers a 4:3 aspect.

Nikon D3400 and Pentax 645D sensor measures

With 39.5MP, the 645D offers a higher resolution than the D3400 (24MP), but the 645D nevertheless has larger individual pixels (pixel pitch of 6.06μm versus 3.91μm for the D3400) due to its larger sensor. However, the D3400 is a much more recent model (by 6 years and 5 months) 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 inch or 92.3 x 69.1 cm, for very good quality (250 dpi) 29.1 x 21.8 inch or 73.8 x 55.3 cm, and for excellent quality (300 dpi) 24.2 x 18.1 inch or 61.5 x 46.1 cm. The corresponding values for the Nikon D3400 are 30 x 20 inch or 76.2 x 50.8 cm for good quality, 24 x 16 inch or 61 x 40.6 cm for very good quality, and 20 x 13.3 inch or 50.8 x 33.9 cm for excellent quality prints.

The Nikon D3400 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Pentax 645D are ISO 100 to ISO 1600 (no boost).

D3400 versus 645D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the D3400 has a notably higher overall DXO score than the 645D (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.2 bits higher color depth, 1.3 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D3400 indeed provides movie recording capabilities, while the 645D does not. The highest resolution format that the D3400 can use is 1080/60p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D3400 and the 645D are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the 645D offers a wider field of view (98%) than the one in the D3400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 645D has a higher magnification (0.78x vs 0.57x), 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 Nikon D3400 and Pentax 645D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D3400 has one, while the 645D does not. While the built-in flash of the D3400 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 D3400 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 D3400 only has one slot. The D3400 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 645D 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 Nikon D3400 and Pentax 645D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Pentax 645D (unlike the D3400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D3400 and the 645D have been discontinued, but can regularly be found used on eBay. The 645D was replaced by the Pentax 645Z, while the D3400 was followed by the Nikon D3500. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Pentax websites.

Review summary

So what is the bottom line? Is the Nikon D3400 better than the Pentax 645D or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Nikon D3400:

  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • Faster burst: Shoots at higher frequency (5 vs 1.1 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (124x98mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1035g or 70 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (1200 versus 800) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (95 percent cheaper at launch).
  • More modern: Reflects 6 years and 5 months of technical progress since the 645D launch.

ilogo

Arguments in favor of the Pentax 645D:

  • More detail: Has more megapixels (39.5 vs 24MP), which boosts linear resolution by 26%.
  • More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.57x).
  • 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.
  • 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 individual advantages (bullet points above) is taken as a guide, the D3400 emerges as the winner of the contest (12 : 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.

D3400 12:09 645D

How about other alternatives? Do the specifications of the Nikon D3400 and the Pentax 645D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 D3400 and the 645D in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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 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.
