Nikon Df vs Olympus E-520
The Nikon Df and the Olympus E-520 are two digital cameras that were officially introduced, respectively, in November 2013 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (Df) and a Four Thirds (E-520) sensor. The Nikon has a resolution of 16.2 megapixels, whereas the Olympus provides 10 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 Df and the Olympus E-520? 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 side-by-side display below illustrates the physical size and weight of the Nikon Df and the Olympus E-520. 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 Df can be obtained in two different colors (black, silver), while the E-520 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-520 is notably smaller (21 percent) than the Nikon Df. Moreover, the E-520 is markedly lighter (30 percent) than the Df. It is worth mentioning in this context that the Df is splash and dust resistant, while the E-520 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 (Df) and the Four Thirds Lens Catalog (E-520).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-520 was launched at a markedly lower price (by 75 percent) than the Df, 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon Df features a full frame sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the Df has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 16.2MP, the Df offers a higher resolution than the E-520 (10MP), but the Df nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 4.74μm for the E-520) due to its larger sensor. Moreover, the Df is a much more recent model (by 5 years and 5 months) than the E-520, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon Df implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Df for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.8 cm. The corresponding values for the Olympus E-520 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.
The Nikon Df has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-204800. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the Df provides substantially higher image quality than the E-520, with an overall score that is 34 points higher. This advantage is based on 3.2 bits higher color depth, 2.7 EV in additional dynamic range, and 2.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Apart from body and sensor, cameras can and do differ across a variety of features. The Df and the E-520 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 viewfinder in the Df offers a wider field of view (100%) than the one in the E-520 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Df has a higher magnification (0.70x 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 Nikon Df, the Olympus E-520, and comparable cameras.
One feature that is present on the Df, but is missing on the E-520 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Nikon Df 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 Df writes its imaging data to SDXC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Df only has one slot.
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 Df and Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon Df (unlike the E-520) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the Df and the E-520 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Nikon and Olympus. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Olympus websites.
So how do things add up? Which of the two cameras – the Nikon Df or the Olympus E-520 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Nikon Df:
- More detail: Offers more megapixels (16.2 vs 10MP) with a 30% higher linear resolution.
- Better image quality: Scores substantially higher (34 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (3.2 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.7 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2.6 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.46x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 215k dots).
- Faster burst: Shoots at higher frequency (5.5 vs 3.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (1400 versus 750) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More modern: Reflects 5 years and 5 months of technical progress since the E-520 launch.
Arguments in favor of the Olympus E-520:
- More compact: Is smaller (136x92mm vs 144x110mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 225g or 30 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- 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 (75 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in May 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the Df is the clear winner of the match-up (16 : 7 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 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.

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 Df and the E-520 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.
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], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
