Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3000 and the Nikon D3100? 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: Nikon D3000 vs D3100
The physical size and weight of the Nikon D3000 and the Nikon D3100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
The D3100 can be obtained in two different colors (black, red), while the D3000 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 Nikon D3100 is somewhat smaller (3 percent) than the Nikon D3000. Moreover, the D3100 is markedly lighter (6 percent) than the D3000. In this context, it is worth noting that neither the D3000 nor the D3100 are weather-sealed.
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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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 two cameras under review were launched at the same price and fall into the same 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: Nikon D3000 vs D3100
The size of the imaging sensor is a crucial determinant 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D3100 is 5 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the D3100 uses a more advanced image processing engine (EXPEED 2) than the D3000 (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the D3100 offers a higher resolution of 14.2 megapixels, compared with 10 MP of the D3000. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.01μm versus 6.11μm for the D3000). However, it should be noted that the D3100 is a somewhat more recent model (by 1 year) than the D3000, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The resolution advantage of the Nikon D3100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3100 for good quality output (200 dots per inch) amounts to 23 x 15.4 inch or 58.5 x 39 cm, for very good quality (250 dpi) 18.4 x 12.3 inch or 46.8 x 31.2 cm, and for excellent quality (300 dpi) 15.4 x 10.2 inch or 39 x 26 cm. The corresponding values for the Nikon D3000 are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D3000 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Nikon D3100 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-12800.
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 D3100 has a markedly higher DXO score than the D3000 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.2 bits higher color depth, 0.2 EV in additional dynamic range, and 0.7 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 are not only capable of taking still images, but can also record movies. The D3100 indeed provides for movie recording, while the D3000 does not. The highest resolution format that the D3100 can use is 1080/24p.
Feature comparison: Nikon D3000 vs D3100
Beyond body and sensor, cameras can and do differ across a range of features. The D3000 and the D3100 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 viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.53x). The following table reports on some other key feature differences and similarities of the Nikon D3000, the Nikon D3100, and comparable cameras.

Both the D3000 and the D3100 have been discontinued, but can regularly be found used on eBay. The D3000 was replaced by the Nikon D3100, while the D3100 was followed by the Nikon D3200. 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: Nikon D3000 vs D3100
So what is the bottom line? Is the Nikon D3000 better than the Nikon D3100 or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Nikon D3000:
- More heavily discounted: Has been on the market for longer (launched in July 2009).
Advantages of the Nikon D3100:
- More detail: Has more megapixels (14.2 vs 10MP), which boosts linear resolution by 19%.
- Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (EXPEED 2 vs EXPEED).
- Broader imaging potential: Can capture not only stills but also 1080/24p video.
- More modern: Was introduced somewhat (1 year) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the D3100 is the clear winner of the contest (6 : 1 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.
How about other alternatives? Do the specifications of the Nikon D3000 and the Nikon D3100 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D3000 or the D3100. 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: Nikon D3000 vs D3100
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 (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 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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
