Olympus E-420 vs Sony A77 II
The Olympus E-420 and the Sony Alpha SLT-A77 II are two digital cameras that were announced, respectively, in March 2008 and May 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a Four Thirds (E-420) and an APS-C (A77 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-420 and the Sony Alpha SLT-A77 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.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Olympus E-420 and the Sony A77 II. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size 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 A77 II is notably larger (26 percent) than the Olympus E-420. Moreover, the A77 II is substantially heavier (47 percent) than the E-420. It is noteworthy in this context that the A77 II is splash and dust-proof, while the E-420 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-420 gets 500 shots out of its Olympus BLS-1 battery, while the A77 II can take 480 images on a single charge of its Sony NP-FM500H power pack.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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-420 was launched at a markedly lower price (by 50 percent) than the A77 II, 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 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-420 features a Four Thirds sensor and the Sony A77 II an APS-C sensor. The sensor area in the A77 II is 63 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-420 has a native 4:3 aspect ratio, while the one in the A77 II offers a 3:2 aspect.
With 24MP, the A77 II offers a higher resolution than the E-420 (10MP), but the A77 II has smaller individual pixels (pixel pitch of 3.91μm versus 4.74μm for the E-420). Yet, the A77 II is a much more recent model (by 6 years and 1 month) than the E-420, 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 A77 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A77 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-420 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 Olympus E-420 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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 A77 II offers substantially better image quality than the E-420 (overall score 26 points higher). The advantage is based on 2.9 bits higher color depth, 3 EV in additional dynamic range, and 0.9 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 A77 II indeed provides for movie recording, while the E-420 does not. The highest resolution format that the A77 II can use is 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A77 II has an electronic viewfinder (2359k dots), while the E-420 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 A77 II offers a wider field of view (100%) than the one in the E-420 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A77 II 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 adjacent table lists some of the other core features of the Olympus E-420 and Sony A77 II along with similar information for a selection of comparators.

One feature that differentiates the A77 II and the E-420 is in-body image stabilization (IBIS). The A77 II reduces the risk of handshake-induced blur with all attached lenses, while the E-420 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The A77 II 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 E-420 does not have a selfie-screen.The E-420 writes its imaging data to Compact Flash or xD Picture cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A77 II 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 E-420 and Sony Alpha SLT-A77 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A77 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-420 does not provide wifi capability.
Studio photographers will appreciate that the Sony A77 II (unlike the E-420) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-420 and the A77 II 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 features and operation of the E-420 and A77 II can be found, respectively, in the Olympus E-420 Manual (free pdf) or the online Sony A77 II Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Olympus E-420 or the Sony A77 II – 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.
Arguments in favor of the Olympus E-420:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More compact: Is smaller (130x91mm vs 143x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 207g or 32 percent) and hence easier to carry around.
- 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 (50 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2008).
Advantages of the Sony Alpha SLT-A77 II:
- More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
- Better image quality: Scores substantially higher (26 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/60p 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).
- Easier setting verification: Features a control panel on top to check shooting parameters.

If the number of relative strengths (bullet points above) is taken as a guide, the A77 II is the clear winner of the contest (22 : 6 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 Olympus E-420 and the Sony A77 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 E-420 and the A77 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.
Expert reviews
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 (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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
