Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-5 and the Nikon D300? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-5 and the Nikon D300. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-5 and the Nikon D300 are of equal size. However, the D300 is markedly heavier (6 percent) than the E-5. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 Four Thirds Lens Catalog (E-5) and the Nikon Lens Catalog (D300).

Concerning battery life, the E-5 gets 750 shots out of its Olympus BLM-5 battery, while the D300 can take 1000 images on a single charge of its Nikon EN-EL3e power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 E-5 was somewhat cheaper (by 6 percent) than the D300 at launch, but both cameras fall into the same price category. 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

The size of the imaging sensor is a crucial determinant 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 Olympus E-5 features a Four Thirds sensor and the Nikon D300 an APS-C sensor. The sensor area in the D300 is 66 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-5 has a native 4:3 aspect ratio, while the one in the D300 offers a 3:2 aspect.

Even though the D300 has a larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the D300 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.53μm versus 4.29μm for the E-5), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the E-5 is much more recent (by 3 years) than the D300, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Olympus E-5 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Nikon D300 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

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.

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 D300 offers substantially better image quality than the E-5 (overall score 11 points higher). The advantage is based on 0.5 bits higher color depth, 1.5 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The E-5 indeed provides movie recording capabilities, while the D300 does not. The highest resolution format that the E-5 can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-5 and the D300 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 (100%), but the viewfinder of the D300 has a higher magnification than the one of the E-5 (0.63x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Olympus E-5, the Nikon D300, and comparable cameras.

One feature that differentiates the E-5 and the D300 is in-body image stabilization (IBIS). The E-5 reduces the risk of handshake-induced blur with all attached lenses, while the D300 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Nikon D300 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 E-5 writes its imaging data to Compact Flash or xD Picture cards, while the D300 uses Compact Flash cards. The E-5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D300 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 Olympus E-5 and Nikon D300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the E-5 and the D300 have been discontinued, but can regularly be found used on ebay. The D300 was replaced by the Nikon D300S, while the E-5 does not have a direct successor. Further information on the features and operation of the E-5 and D300 can be found, respectively, in the Olympus E-5 Manual (free pdf) or the online Nikon D300 Manual.

Review summary

So how do things add up? Which of the two cameras – the Olympus E-5 or the Nikon D300 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Olympus E-5:

• Broader imaging potential: Can record not only still images but also 720/30p movies.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 3 years of technical progress since the D300 launch.

Arguments in favor of the Nikon D300:

• Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.58x).
• Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Gets more shots (1000 versus 750) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in August 2007).

If the number of relative strengths (bullet points above) is taken as a guide, the D300 emerges as the winner of the match-up (8 : 6 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.

How about other alternatives? Do the specifications of the Olympus E-5 and the Nikon D300 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 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 E-5 or the D300 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 where reviews by experts come in. 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.

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

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
