Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3200 and the Olympus E-420? 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 Nikon D3200 and the Olympus E-420 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The D3200 can be obtained in two different colors (black, red), while the E-420 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-420 is somewhat smaller (1 percent) than the Nikon D3200. Moreover, the E-420 is markedly lighter (13 percent) than the D3200. In this context, it is worth noting that neither the D3200 nor the E-420 are weather-sealed.

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 (D3200) and the Four Thirds Lens Catalog (E-420).

Concerning battery life, the D3200 gets 540 shots out of its Nikon EN-EL14 battery, while the E-420 can take 500 images on a single charge of its Olympus BLS-1 power pack.

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 two cameras under review were launched at the same price and fall into the same 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 imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D3200 features an APS-C sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 is 37 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 D3200 has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.

With 24.1MP, the D3200 offers a higher resolution than the E-420 (10MP), but the D3200 has smaller individual pixels (pixel pitch of 3.85μm versus 4.74μm for the E-420). However, the D3200 is a much more recent model (by 4 years and 1 month) than the E-420, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D3200 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3200 for good quality output (200 dots per inch) amounts to 30.1 x 20 inches or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inches or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inches or 50.9 x 33.9 cm. The corresponding values for the Olympus E-420 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 D3200 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus E-420 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 D3200 provides substantially higher image quality than the E-420, with an overall score that is 25 points higher. This advantage is based on 2.6 bits higher color depth, 2.8 EV in additional dynamic range, and 1.1 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 cannot only take still pictures, but also record videos. The D3200 indeed provides movie recording capabilities, while the E-420 does not. The highest resolution format that the D3200 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D3200 and the E-420 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 (95%), but the viewfinder of the D3200 has a higher magnification than the one of the E-420 (0.53x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D3200 and Olympus E-420 along with similar information for a selection of comparators.

The D3200 writes its imaging data to SDXC cards, while the E-420 uses Compact Flash or xD Picture cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D3200 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 Nikon D3200 and Olympus E-420 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D3200 and the E-420 have been discontinued, but can regularly be found used on ebay. The D3200 was replaced by the Nikon D3300, while the E-420 does not have a direct successor. Further information on the features and operation of the D3200 and E-420 can be found, respectively, in the Nikon D3200 Manual (free pdf) or the online Olympus E-420 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D3200 or the Olympus E-420 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon D3200:

• More detail: Offers more megapixels (24.1 vs 10MP) with a 58% higher linear resolution.
• Better image quality: Scores substantially higher (25 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.8 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.46x).
• Larger screen: Has a bigger rear LCD (3.0" 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 (4 vs 3.5 flaps/sec) to capture the decisive moment.
• More modern: Reflects 4 years and 1 month of technical progress since the E-420 launch.

Advantages of the Olympus E-420:

• Less heavy: Has a lower weight (by 65g or 13 percent) and is thus easier to take along.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in March 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the D3200 is the clear winner of the match-up (11 : 3 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.

How about other alternatives? Do the specifications of the Nikon D3200 and the Olympus E-420 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 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 D3200 and the E-420 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.

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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
