Nikon Df versus 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 sensor. The Nikon has a resolution of 16.2 megapixel, whereas the Olympus provides 10 MP.
The side-by-side display below illustrates the physical size and weight of the Nikon Df and the Olympus E-520. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the Df – represents the basis or 100 percent across all the size and weight measures).
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 find an overview of optics 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels 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 associated with larger, more expensive camera bodies 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.
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 somewhat more recent model (by 5 years and 5 months) than the E-520, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 table below summarizes some of the other core capabilities of the Nikon Df and Olympus E-520 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The Df is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-520 has been discontinued (but it can be found pre-owned on ebay). There has not been a direct replacement model for the E-520 from Olympus.
So how do things add up? Is there a clear favorite between the Nikon Df and the Nikon Df? Below is a summary of the relative strengths of each of the two contestants.
Advantages of 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).
- Easier setting verification: Has 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.
- 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.
- More modern: Reflects 5 years and 5 months of technical progress since the E-520 launch.
Reasons to prefer 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.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
- 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 (12 : 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the Df and the E-520 in practical situations. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
