Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon D300S and the Olympus E-PL7. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The E-PL7 can be obtained in two different colors (black, silver), while the D300S is only available in black.

Compare D300S versus E-PL7 top
Comparison D300S or E-PL7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL7 is considerably smaller (54 percent) than the Nikon D300S. Moreover, the E-PL7 is substantially lighter (62 percent) than the D300S. It is worth mentioning in this context that the D300S is splash and dust resistant, while the E-PL7 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 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 (D300S) and the Micro Four Thirds Lens Catalog (E-PL7). Mirrorless cameras, such as the E-PL7, 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 D300S gets 950 shots out of its Nikon EN-EL3e battery, while the E-PL7 can take 350 images on a single charge of its Olympus BLS-50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-PL7 was launched at a markedly lower price (by 67 percent) than the D300S, 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 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D300S features an APS-C sensor and the Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 is 40 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 D300S has a native 3:2 aspect ratio, while the one in the E-PL7 offers a 4:3 aspect.

Nikon D300S and Olympus E-PL7 sensor measures

Despite having a smaller sensor, the E-PL7 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the D300S. 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 5.53μm for the D300S). However, it should be noted that the E-PL7 is much more recent (by 5 years) than the D300S, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Olympus E-PL7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL7 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Nikon D300S are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Nikon D300S has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Olympus PEN E-PL7 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.

D300S versus E-PL7 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-PL7 provides a better video resolution than the D300S. It can shoot movie footage at 1080/30p, while the Nikon is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D300S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The table below summarizes some of the other core capabilities of the Nikon D300S and Olympus E-PL7 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 D300S has one, while the E-PL7 does not. While the built-in flash of the D300S is not very powerful, it can at times be useful as a fill-in light.

The E-PL7 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 D300S does not have a selfie-screen.

The Nikon D300S and the Olympus E-PL7 both have 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 D300S writes its imaging data to Compact Flash or SDXC cards, while the E-PL7 uses SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL7 only has one slot. The E-PL7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D300S cannot take advantage of Ultra High Speed SD cards.

It is notable that the D300S has a microphone port, which is missing on the E-PL7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Nikon D300S (unlike the E-PL7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D300S and the E-PL7 have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the E-PL7 was followed by the Olympus E-PL8. Further information on the features and operation of the D300S and E-PL7 can be found, respectively, in the Nikon D300S Manual (free pdf) or the online Olympus E-PL7 Manual.

  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 available for much longer (launched in July 2009).

ilogo

Advantages of the Olympus PEN E-PL7:

  • More detail: Has more megapixels (15.9 vs 12.2MP), which boosts linear resolution by 12%.
  • Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 920k 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 7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (115x67mm vs 147x115mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 581g or 62 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
  • More modern: Reflects 5 years of technical progress since the D300S launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-PL7 is the clear winner of the contest (15 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

D300S 10:15 E-PL7

How about other alternatives? Do the specifications of the Nikon D300S and the Olympus E-PL7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D300S or the E-PL7. 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

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
