Nikon D300 vs Sony NEX-3
The Nikon D300 and the Sony Alpha NEX-3 are two digital cameras that were officially introduced, respectively, in August 2007 and May 2010. The D300 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 12.2 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 D300 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.
The side-by-side display below illustrates the physical size and weight of the Nikon D300 and the Sony NEX-3. 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 NEX-3 can be obtained in three different colors (black, silver, red), while the D300 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 (57 percent) than the Nikon D300. Moreover, the NEX-3 is substantially lighter (68 percent) than the D300. It is worth mentioning in this context that the D300 is splash and dust resistant, while the NEX-3 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. 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 (D300) 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 NEX-3 was launched at a markedly lower price (by 67 percent) than the D300, 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 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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-3 is 2 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a slightly smaller sensor, the NEX-3 offers a higher resolution of 14 megapixels, compared with 12.2 MP of the D300. 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 5.53μm for the D300). However, it should be noted that the NEX-3 is much more recent (by 2 years and 8 months) than the D300, 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 inch or 58.3 x 38.8 cm, for very good quality (250 dpi) 18.4 x 12.2 inch or 46.7 x 31 cm, and for excellent quality (300 dpi) 15.3 x 10.2 inch or 38.9 x 25.9 cm. The corresponding values for the Nikon D300 are 21.4 x 14.2 inch or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inch or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inch or 36.3 x 24.1 cm for excellent quality prints.
The Nikon D300 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).
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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The NEX-3 indeed provides for movie recording, while the D300 does not. The highest resolution format that the NEX-3 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D300 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 following table reports on some other key feature differences and similarities of the Nikon D300, the Sony NEX-3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D300 has one, while the NEX-3 does not. While the built-in flash of the D300 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 D300 does not have a selfie-screen.
The Nikon D300 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 D300 writes its imaging data to Compact Flash cards, while the NEX-3 uses SDXC or Memory Stick PRO Duo cards.
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 D300 and Sony Alpha NEX-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D300 (unlike the NEX-3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D300 and the NEX-3 have been discontinued, but can regularly be found used on eBay. The D300 was replaced by the Nikon D300S, while the NEX-3 was followed by the Sony NEX-3N. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.
So how do things add up? Which of the two cameras – the Nikon D300 or the Sony NEX-3 – 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 D300:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (1000 versus 330) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in August 2007).
Arguments in favor of the Sony Alpha NEX-3:
- More detail: Has more megapixels (14 vs 12.2MP), which boosts linear resolution by 7%.
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- 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 6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x62mm vs 147x114mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 628g or 68 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
- More modern: Reflects 2 years and 8 months of technical progress since the D300 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3 comes out slightly ahead of the D300 (10 : 9 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 D300 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 says little about, for example, the shooting experience and imaging performance of the D300 and the NEX-3 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 (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.
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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
