Olympus E-450 vs Sony NEX-7

The Olympus E-450 and the Sony Alpha NEX-7 are two digital cameras that were officially introduced, respectively, in March 2009 and August 2011. The E-450 is a DSLR, while the NEX-7 is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-450) and an APS-C (NEX-7) sensor. The Olympus has a resolution of 10 megapixels, whereas the Sony provides 24 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 Olympus E-450 and the Sony Alpha NEX-7? 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: Olympus E-450 vs Sony NEX-7

The side-by-side display below illustrates the physical size and weight of the Olympus E-450 and the Sony NEX-7. 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.

Compare E-450 versus NEX-7 top
Comparison E-450 or NEX-7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-7 is considerably smaller (32 percent) than the Olympus E-450. Moreover, the NEX-7 is markedly lighter (9 percent) than the E-450. In this context, it is worth noting that neither the E-450 nor the NEX-7 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 Four Thirds Lens Catalog (E-450) and the Sony E-Mount Lens Catalog (NEX-7). Mirrorless cameras, such as the NEX-7, 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 E-450 gets 500 shots out of its BLS-1 battery, while the NEX-7 can take 430 images on a single charge of its NP-FW50 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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-450 was launched at a markedly lower price (by 63 percent) than the NEX-7, which puts it into a different market segment. 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: Olympus E-450 vs Sony NEX-7

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-450 features a Four Thirds sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 62 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-450 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.

Olympus E-450 and Sony NEX-7 sensor measures

With 24MP, the NEX-7 offers a higher resolution than the E-450 (10MP), but the NEX-7 has smaller individual pixels (pixel pitch of 3.90μm versus 4.74μm for the E-450). Yet, the NEX-7 is a much more recent model (by 2 years and 4 months) than the E-450, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-450 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-450 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).

E-450 versus NEX-7 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the NEX-7 offers substantially better image quality than the E-450 (overall score 25 points higher). The advantage is based on 2.6 bits higher color depth, 2.9 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 also of capturing video footage. The NEX-7 indeed provides for movie recording, while the E-450 does not. The highest resolution format that the NEX-7 can use is 1080/60i.

 

Feature comparison: Olympus E-450 vs Sony NEX-7

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the NEX-7 has an electronic viewfinder (2359k dots), while the E-450 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the NEX-7 offers a wider field of view (100%) than the one in the E-450 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the NEX-7 has a higher magnification (0.73x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Olympus E-450, the Sony NEX-7, and comparable cameras.

Both the E-450 and the NEX-7 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Olympus and Sony. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.


Review summary: Olympus E-450 vs Sony NEX-7

So how do things add up? Is the Olympus E-450 better than the Sony NEX-7 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Olympus E-450:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Can take more shots (500 versus 430) on a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in March 2009).

ilogo

Reasons to prefer the Sony Alpha NEX-7:

  • More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
  • Better image quality: Scores substantially higher (25 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60i video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x 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).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (10 vs 3.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 130x91mm) and will fit more readily into a bag.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More modern: Reflects 2 years and 4 months of technical progress since the E-450 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the NEX-7 is the clear winner of the contest (16 : 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 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 Olympus E-450 and the Sony NEX-7 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 E-450 or the NEX-7. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Olympus E-450 vs Sony NEX-7

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
