Nikon D3100 vs D3X

The Nikon D3100 and the Nikon D3X are two digital cameras that were revealed to the public, respectively, in August 2010 and December 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D3100) and a full frame (D3X) sensor. The D3100 has a resolution of 14.2 megapixels, whereas the D3X provides 24.4 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 D3100 and the Nikon D3X? 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 D3100 and the Nikon D3X are illustrated 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 size dimensions are rounded to the nearest millimeter.

The D3100 can be obtained in two different colors (black, red), while the D3X is only available in black.

Size Nikon D3100 vs Nikon D3X
Compare D3100 versus D3X top
Comparison D3100 or D3X rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3X is considerably larger (111 percent) than the Nikon D3100. Moreover, the D3X is substantially heavier (150 percent) than the D3100. It is noteworthy in this context that the D3X is splash and dust-proof, while the D3100 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. A larger imaging sensor (as in the D3X) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D3100). You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D3100 gets 550 shots out of its EN-EL14 battery, while the D3X can take 4400 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the D3100, there are third party battery grips available as optional accessories (see here on eBay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 obviously take relative prices into account. 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 D3100 was launched at a markedly lower price (by 93 percent) than the D3X, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D3100 features an APS-C sensor and the Nikon D3X a full frame sensor. The sensor area in the D3X is 142 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the D3100 uses a more advanced image processing engine (EXPEED 2) than the D3X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

Nikon D3100 and Nikon D3X sensor measures

With 24.4MP, the D3X offers a higher resolution than the D3100 (14.2MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 5.01μm for the D3100) due to its larger sensor. However, the D3100 is a somewhat more recent model (by 1 year and 8 months) than the D3X, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D3X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3X for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Nikon D3100 are 23 x 15.4 inches or 58.5 x 39 cm for good quality, 18.4 x 12.3 inches or 46.8 x 31.2 cm for very good quality, and 15.4 x 10.2 inches or 39 x 26 cm for excellent quality prints.

The Nikon D3100 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Nikon D3X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-6400.

D3100 versus D3X MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the D3X offers substantially better image quality than the D3100 (overall score 21 points higher). The advantage is based on 2.2 bits higher color depth, 2.4 EV in additional dynamic range, and 1.1 stops in additional 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 cannot only take still pictures, but also record videos. The D3100 indeed provides movie recording capabilities, while the D3X does not. The highest resolution format that the D3100 can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D3100 and the D3X 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 D3X offers a wider field of view (100%) than the one in the D3100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D3X has a higher magnification (0.70x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3100 and Nikon D3X 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 D3100 has one, while the D3X does not. While the built-in flash of the D3100 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D3X 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 D3100 writes its imaging data to SDXC cards, while the D3X uses Compact Flash cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the D3100 only has one slot.

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 D3100 and Nikon D3X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D3X (unlike the D3100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D3100 and the D3X have been discontinued, but can regularly be found used on eBay. The D3100 was replaced by the Nikon D3200, while the D3X does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

Review summary

So how do things add up? Is the Nikon D3100 better than the Nikon D3X or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Nikon D3100:

  • Better jpgs: Has a more modern image processing engine (EXPEED 2 vs EXPEED).
  • Broader imaging potential: Can record not only still images but also 1080/24p movies.
  • More compact: Is smaller (124x96mm vs 160x157mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 755g or 60 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (93 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 8 months after the D3X).


Advantages of the Nikon D3X:

  • More detail: Has more megapixels (24.4 vs 14.2MP), which boosts linear resolution by 31%.
  • Better image quality: Scores substantially higher (21 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (4400 versus 550) 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 on the market for longer (launched in December 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the D3X is the clear winner of the contest (18 : 7 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 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.

D3100 07:18 D3X

How about other alternatives? Do the specifications of the Nikon D3100 and the Nikon D3X 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D3100 or the D3X perform in practice. 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 expert reviews are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
