The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Nikon D3100 was launched in the US market at a price of $599. 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 with a 35mm slide

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

The Nikon D3100 features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the Nikon D3100 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Nikon D3100 sensor measures

For most 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One convenient feature of the D3100 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the D3100. 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.

Nikon D3100 FAQ

Below are some additional questions and answers concerning some particular features of the D3100.

What technology is the imaging sensor in the D3100 based on?

The camera is build around a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.

Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?

Nikon equipped the D3100 with the EXPEED 2 image processor.

What is the ISO sensitivity range of the D3100?

The camera has a native sensitivity range from ISO 100 to ISO 3200.

What is the life expectancy of the shutter in the Nikon D3100?

Nikon mentions a shutter rating of 100 000 actuations for the D3100. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the D3100 over, say, three years, one would have to take about 100 pictures each and every day.

How do I find the shutter count on my Nikon D3100?

Nikon embeds the number of shutter actuations in image metadata. You can check the number of shots that your D3100 has taken up to now by uploading a recent image to the online shutter count app.

Does the Nikon D3100 feature an autofocus assist light?

Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.

What is the fastest shutter speed that can be used with flash?

The D3100's flash sync speed is 1/200 sec.

Which battery does the D3100 use?

The camera gets its power from the EN-EL14 (here at amazon), which is a rechargeable Lithium-Ion power pack.

Is there a vertical grip available for the D3100?

Nikon does not offer an optional battery grip, but third party suppliers do (see here on eBay).
