Nikon D40 vs Sony NEX-3
The Nikon D40 and the Sony Alpha NEX-3 are two digital cameras that were revealed to the public, respectively, in November 2006 and May 2010. The D40 is a DSLR, while the NEX-3 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Nikon has a resolution of 6 megapixels, whereas the Sony provides 14 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 Sony Alpha NEX-3? 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 Sony NEX-3. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The NEX-3 can be obtained in three different colors (black, silver, red), while the D40 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 Sony NEX-3 is considerably smaller (38 percent) than the Nikon D40. Moreover, the NEX-3 is substantially lighter (43 percent) than the D40. In this context, it is worth noting that neither the D40 nor the NEX-3 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. 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 Nikon Lens Catalog (D40) and the Sony E-Mount Lens Catalog (NEX-3). Mirrorless cameras, such as the NEX-3, 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 Nikon EN-EL9 battery, while the NEX-3 can take 330 images on a single charge of its Sony NP-FW50 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 D40 was launched at a somewhat lower price (by 17 percent) than the NEX-3, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-3 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the NEX-3 offers a higher resolution of 14 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 5.11μm versus 7.85μm for the D40). However, it should be noted that the NEX-3 is much more recent (by 3 years and 5 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 Sony NEX-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3 for good quality output (200 dots per inch) amounts to 23 x 15.3 inches or 58.3 x 38.8 cm, for very good quality (250 dpi) 18.4 x 12.2 inches or 46.7 x 31 cm, and for excellent quality (300 dpi) 15.3 x 10.2 inches or 38.9 x 25.9 cm. The corresponding values for the Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches 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 Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).
In terms of underlying technology, the D40 is build around a CCD sensor, while the NEX-3 uses a CMOS imager. 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 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 NEX-3 offers substantially better image quality than the D40 (overall score 12 points higher). The advantage is based on 1.1 bits higher color depth, 1 EV in additional dynamic range, and 0.6 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 NEX-3 indeed provides for movie recording, while the D40 does not. The highest resolution format that the NEX-3 can use is 720/30p.
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 NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The table below summarizes some of the other core capabilities of the Nikon D40 and Sony NEX-3 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D40 has one, while the NEX-3 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 NEX-3 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 D40 writes its imaging data to SDHC cards, while the NEX-3 uses SDXC or Memory Stick PRO Duo 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 Sony Alpha NEX-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40 and the NEX-3 have been discontinued, but can regularly be found used on ebay. The D40 was replaced by the Nikon D40X, while the NEX-3 was followed by the Sony NEX-3N. Further information on the features and operation of the D40 and NEX-3 can be found, respectively, in the Nikon D40 Manual (free pdf) or the online Sony NEX-3 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Nikon D40 or the Sony NEX-3 – 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.
Advantages of the Nikon D40:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (470 versus 330) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in November 2006).
Reasons to prefer the Sony Alpha NEX-3:
- More detail: Has more megapixels (14 vs 6MP), which boosts linear resolution by 53%.
- Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (7 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x62mm vs 124x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 225g or 43 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Reflects 3 years and 5 months of technical progress since the D40 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3 is the clear winner of the contest (15 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Nikon D40 and the Sony NEX-3 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40 or the NEX-3. 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 why expert reviews are important. 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
