Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL7 and the Sony Alpha A900? 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 Olympus E-PL7 and the Sony A900. 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 E-PL7 can be obtained in two different colors (black, silver), while the A900 is only available in black.

Compare E-PL7 versus A900 top
Comparison E-PL7 or A900 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A900 is considerably larger (137 percent) than the Olympus E-PL7. Moreover, the A900 is substantially heavier (151 percent) than the E-PL7. It is noteworthy in this context that the A900 is splash and dust-proof, while the E-PL7 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-PL7 gets 350 shots out of its BLS-50 battery, while the A900 can take 880 images on a single charge of its NP-FM500H power pack.

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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-PL7 was launched at a markedly lower price (by 80 percent) than the A900, 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

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-PL7 features a Four Thirds sensor and the Sony A900 a full frame sensor. The sensor area in the A900 is 283 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-PL7 has a native 4:3 aspect ratio, while the one in the A900 offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Olympus E-PL7 and Sony A900 sensor measures

With 24.4MP, the A900 offers a higher resolution than the E-PL7 (15.9MP), but the A900 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the E-PL7) due to its larger sensor. However, the E-PL7 is a much more recent model (by 5 years and 11 months) than the A900, 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 A900 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A900 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Olympus E-PL7 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Olympus PEN E-PL7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha A900 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

E-PL7 versus A900 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the A900 has a markedly higher DXO score than the E-PL7 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.1 EV of lower dynamic range, and 0.7 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 movie recording capabilities, while the A900 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 A900 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. The table below summarizes some of the other core capabilities of the Olympus E-PL7 and Sony A900 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-PL7 has a touchscreen, while the A900 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-PL7 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A900 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 E-PL7 writes its imaging data to SDXC cards, while the A900 uses Compact Flash or Memory Stick PRO Duo cards. The A900 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL7 only has one slot.

 

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 Olympus PEN E-PL7 and Sony Alpha A900 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, while the A900 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Sony A900 (unlike the E-PL7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-PL7 and the A900 have been discontinued, but can regularly be found used on eBay. The A900 was replaced by the Sony A99, 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 Olympus and Sony websites.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-PL7 or the Sony A900 – 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.

ilogo

Advantages of the Olympus PEN E-PL7:

  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 922k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (115x67mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 538g or 60 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
  • More modern: Reflects 5 years and 11 months of technical progress since the A900 launch.

ilogo

Reasons to prefer the Sony Alpha A900:

  • More detail: Has more megapixels (24.4 vs 15.9MP), which boosts linear resolution by 26%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Longer lasting: Gets more shots (880 versus 350) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the E-PL7 emerges as the winner of the contest (13 : 11 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 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.

E-PL7 13:11 A900

How about other alternatives? Do the specifications of the Olympus E-PL7 and the Sony A900 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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-PL7 and the A900 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
