Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark II and the Olympus E-510? 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

An illustration of the physical size and weight of the Olympus E-M5 II and the Olympus E-510 is provided 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 dimensions are rounded to the nearest millimeter.

The E-M5 II can be obtained in two different colors (black, silver), while the E-510 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 Olympus E-510 is notably larger (19 percent) than the Olympus E-M5 II. Moreover, the E-510 is markedly heavier (15 percent) than the E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the E-510 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (E-M5 II) and the Four Thirds Lens Catalog (E-510). Mirrorless cameras, such as the Olympus E-M5 II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the E-M5 II gets 310 shots out of its Olympus BLN-1 battery, while the E-510 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-510 was launched at a markedly lower price (by 27 percent) than the E-M5 II, 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. 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of chip-set technology, the E-M5 II uses a more advanced image processing engine (TruePic VII) than the E-510 (TruePic III), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the E-M5 II offers a higher resolution of 15.9 megapixels, compared with 10 MP of the E-510. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M5 II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.74μm for the E-510). In this context, it should be noted, however, that the E-M5 II is much more recent (by 7 years and 11 months) than the E-510, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Olympus E-M5 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 II 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 Olympus E-510 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

Unlike the E-510, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus OM-D E-M5 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus E-510 are ISO 100 to ISO 1600 (no boost).

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 review, the E-M5 II provides substantially higher image quality than the E-510, with an overall score that is 21 points higher. This advantage is based on 1.8 bits higher color depth, 2.5 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. 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 can also record movies. The E-M5 II indeed provides movie recording capabilities, while the E-510 does not. The highest resolution format that the E-M5 II can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M5 II has an electronic viewfinder (2360k dots), while the E-510 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the E-M5 II offers a wider field of view (100%) than the one in the E-510 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M5 II has a higher magnification (0.74x vs 0.46x), 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-M5 II, the Olympus E-510, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M5 II has a touchscreen, while the E-510 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M5 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M5 II 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-M5 II writes its imaging data to SDXC cards, while the E-510 uses Compact Flash or xD Picture cards. The E-510 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 II 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 OM-D E-M5 Mark II and Olympus E-510 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 II offers wifi support, while the E-510 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the E-510) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M5 II and the E-510 have been discontinued, but can regularly be found used on ebay. The E-510 was replaced by the Olympus E-520, while the E-M5 II was followed by the Olympus E-M5 III. Further information on the features and operation of the E-M5 II and E-510 can be found, respectively, in the Olympus E-M5 II Manual (free pdf) or the online Olympus E-510 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M5 II or the Olympus E-510 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Olympus E-510:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Gets more shots (750 versus 310) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in March 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 II is the clear winner of the match-up (27 : 6 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 Olympus E-M5 II and the Olympus E-510 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the E-M5 II and the E-510 in practical situations. 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 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.

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

The review scores listed above should be treated 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 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.
