Nikon D3100 vs Olympus E-PL6
The Nikon D3100 and the Olympus PEN E-PL6 are two digital cameras that were announced, respectively, in August 2010 and May 2013. The D3100 is a DSLR, while the E-PL6 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D3100) and a Four Thirds (E-PL6) sensor. The Nikon has a resolution of 14.2 megapixels, whereas the Olympus provides 15.9 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 Olympus PEN E-PL6? 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.
The physical size and weight of the Nikon D3100 and the Olympus E-PL6 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 D3100 can be obtained in two different colors (black, red), while the E-PL6 is available in four color-versions (black, silver, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL6 is considerably smaller (40 percent) than the Nikon D3100. Moreover, the E-PL6 is substantially lighter (36 percent) than the D3100. In this context, it is worth noting that neither the D3100 nor the E-PL6 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D3100) and the Micro Four Thirds Lens Catalog (E-PL6). Mirrorless cameras, such as the E-PL6, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the D3100 gets 550 shots out of its EN-EL14 battery, while the E-PL6 can take 360 images on a single charge of its BLS-5 power pack.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 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.
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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D3100 features an APS-C sensor and the Olympus E-PL6 a Four Thirds sensor. The sensor area in the E-PL6 is 37 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D3100 has a native 3:2 aspect ratio, while the one in the E-PL6 offers a 4:3 aspect.
Despite having a smaller sensor, the E-PL6 offers a higher resolution of 15.9 megapixels, compared with 14.2 MP of the D3100. 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 3.76μm versus 5.01μm for the D3100). However, it should be noted that the E-PL6 is much more recent (by 2 years and 8 months) than the D3100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
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 Olympus PEN E-PL6 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-PL6 provides a faster frame rate than the D3100. It can shoot movie footage at 1080/30p, while the Nikon is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D3100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL6 relies on live view and the rear LCD for framing. That said, the E-PL6 can be equipped with an optional viewfinder – the VF-3. The following table reports on some other key feature differences and similarities of the Nikon D3100, the Olympus E-PL6, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D3100 has one, while the E-PL6 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 E-PL6 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 D3100 does not have a selfie-screen.
The Olympus E-PL6 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 D3100 and the E-PL6 write their files to SDXC cards. The E-PL6 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3100 cannot take advantage of Ultra High Speed SD cards.
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 Olympus PEN E-PL6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D3100 and the E-PL6 have been discontinued, but can regularly be found used on ebay. The D3100 was replaced by the Nikon D3200, while the E-PL6 was followed by the Olympus E-PL7. Further information on the features and operation of the D3100 and E-PL6 can be found, respectively, in the Nikon D3100 Manual (free pdf) or the online Olympus E-PL6 Manual.
So what conclusions can be drawn? Which of the two cameras – the Nikon D3100 or the Olympus E-PL6 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D3100:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (550 versus 360) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in August 2010).
Reasons to prefer the Olympus PEN E-PL6:
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (111x64mm vs 124x96mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 180g or 36 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 8 months of technical progress since the D3100 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-PL6 is the clear winner of the contest (13 : 8 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.
How about other alternatives? Do the specifications of the Nikon D3100 and the Olympus E-PL6 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D3100 or the E-PL6 perform in practice. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
