Nikon D40 vs Olympus E-PL7

The Nikon D40 and the Olympus PEN E-PL7 are two digital cameras that were revealed to the public, respectively, in November 2006 and August 2014. The D40 is a DSLR, while the E-PL7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40) and a Four Thirds (E-PL7) sensor. The Nikon has a resolution of 6 megapixels, whereas the Olympus provides 15.9 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 D40 and the Olympus PEN E-PL7? 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 Nikon D40 and the Olympus E-PL7. 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 measures are rounded to the nearest millimeter.

The E-PL7 can be obtained in two different colors (black, silver), while the D40 is only available in black.

Size Nikon D40 vs Olympus E-PL7
Compare D40 versus E-PL7 top
Comparison D40 or E-PL7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL7 is considerably smaller (34 percent) than the Nikon D40. Moreover, the E-PL7 is markedly lighter (32 percent) than the D40. In this context, it is worth noting that neither the D40 nor the E-PL7 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 (D40) and the Micro Four Thirds Lens Catalog (E-PL7). Mirrorless cameras, such as the E-PL7, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D40 gets 470 shots out of its EN-EL9 battery, while the E-PL7 can take 350 images on a single charge of its BLS-50 power pack.

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

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 D40 was launched at a somewhat lower price (by 17 percent) than the E-PL7, which makes it more attractive for photographers on a tight budget. 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.

 

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. 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.

Of the two cameras under consideration, the Nikon D40 features an APS-C sensor and the Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 is 39 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 D40 has a native 3:2 aspect ratio, while the one in the E-PL7 offers a 4:3 aspect.

Nikon D40 and Olympus E-PL7 sensor measures

Despite having a smaller sensor, the E-PL7 offers a higher resolution of 15.9 megapixels, compared with 6 MP of the D40. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 7.85μm for the D40). However, it should be noted that the E-PL7 is much more recent (by 7 years and 9 months) than the D40, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Olympus E-PL7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL7 for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Nikon D40 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.

The Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. The corresponding ISO settings for the Olympus PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

D40 versus E-PL7 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the E-PL7 offers substantially better image quality than the D40 (overall score 16 points higher). The advantage is based on 1.7 bits higher color depth, 1.4 EV in additional dynamic range, and 0.6 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The E-PL7 indeed provides for movie recording, while the D40 does not. The highest resolution format that the E-PL7 can use is 1080/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D40 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4.

One difference between the cameras concerns the presence of an on-board flash. The D40 has one, while the E-PL7 does not. While the built-in flash of the D40 is not very powerful, it can at times be useful as a fill-in light.

The E-PL7 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D40 does not have a selfie-screen.

The Olympus E-PL7 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 D40 writes its imaging data to SDHC cards, while the E-PL7 uses SDXC cards. The E-PL7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40 cannot take advantage of Ultra High Speed SD cards.

 

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 D40 and Olympus PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40 does not offer wifi capability.

Both the D40 and the E-PL7 have been discontinued, but can regularly be found used on eBay. The D40 was replaced by the Nikon D40X, while the E-PL7 was followed by the Olympus E-PL8. 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.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Nikon D40 and the Olympus E-PL7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

  • More modern: Reflects 7 years and 9 months of technical progress since the D40 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-PL7 is the clear winner of the contest (20 : 5 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 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.

D40 05:20 E-PL7

How about other alternatives? Do the specifications of the Nikon D40 and the Olympus E-PL7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40 or the E-PL7. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
