Olympus E-450 vs Sony A7 II
The Olympus E-450 and the Sony Alpha A7 II are two digital cameras that were officially introduced, respectively, in March 2009 and November 2014. The E-450 is a DSLR, while the A7 II is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-450) and a full frame (A7 II) 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 A7 II? 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 physical size and weight of the Olympus E-450 and the Sony A7 II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 II is somewhat larger (3 percent) than the Olympus E-450. Moreover, the A7 II is substantially heavier (36 percent) than the E-450. It is noteworthy in this context that the A7 II is splash and dust-proof, while the E-450 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. 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 FE Lens Catalog (A7 II). Mirrorless cameras, such as the A7 II, 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 A7 II can take 350 images on a single charge of its NP-FW50 power pack. The power pack in the A7 II can be charged via the USB port, which can be very convenient when travelling.
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 E-450 was launched at a markedly lower price (by 75 percent) than the A7 II, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Olympus E-450 features a Four Thirds sensor and the Sony A7 II a full frame sensor. The sensor area in the A7 II is 280 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-450 has a native 4:3 aspect ratio, while the one in the A7 II offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the A7 II offers a higher resolution than the E-450 (10MP), but the A7 II nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 4.74μm for the E-450) due to its larger sensor. Moreover, the A7 II is a much more recent model (by 5 years and 7 months) than the E-450, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A7 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 II for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-450 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 A7 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus E-450 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha A7 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 A7 II offers substantially better image quality than the E-450 (overall score 34 points higher). The advantage is based on 3.4 bits higher color depth, 3.1 EV in additional dynamic range, and 2.3 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 A7 II indeed provides for movie recording, while the E-450 does not. The highest resolution format that the A7 II can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7 II has an electronic viewfinder (2400k 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 A7 II 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 A7 II has a higher magnification (0.71x 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 Olympus E-450 and Sony A7 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-450 has one, while the A7 II does not. While the built-in flash of the E-450 is not very powerful, it can at times be useful as a fill-in light.
The E-450 writes its imaging data to Compact Flash or xD Picture cards, while the A7 II uses SDXC or Memory Stick PRO Duo cards. The E-450 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7 II only has one slot.
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 Olympus E-450 and Sony Alpha A7 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-450 does not provide wifi capability.
Both the E-450 and the A7 II have been discontinued, but can regularly be found used on eBay. The A7 II was replaced by the Sony A7 III, while the E-450 does not have a direct successor. 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.

If the count of individual advantages (bullet points above) is taken as a guide, the A7 II is the clear winner of the contest (22 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 A7 II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-450 and the A7 II in practical situations. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
