Olympus E-510 vs Sony A5100

The Olympus E-510 and the Sony Alpha A5100 are two digital cameras that were announced, respectively, in March 2007 and August 2014. The E-510 is a DSLR, while the A5100 is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-510) and an APS-C (A5100) 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.

Body comparison

An illustration of the physical size and weight of the Olympus E-510 and the Sony A5100 is provided in the side-by-side display below. 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 A5100 can be obtained in two different colors (black, white), while the E-510 is only available in black.

Compare E-510 versus A5100 top
Comparison E-510 or A5100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A5100 is considerably smaller (45 percent) than the Olympus E-510. Moreover, the A5100 is substantially lighter (47 percent) than the E-510. In this context, it is worth noting that neither the E-510 nor the A5100 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-510) and the Sony E-Mount Lens Catalog (A5100). Mirrorless cameras, such as the A5100, 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-510 gets 750 shots out of its Olympus BLM-1 battery, while the A5100 can take 400 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A5100 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 A5100 was launched at a markedly lower price (by 31 percent) than the E-510, 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. 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. 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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-510 features a Four Thirds sensor and the Sony A5100 an APS-C sensor. The sensor area in the A5100 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-510 has a native 4:3 aspect ratio, while the one in the A5100 offers a 3:2 aspect.

Olympus E-510 and Sony A5100 sensor measures

With 24MP, the A5100 offers a higher resolution than the E-510 (10MP), but the A5100 has smaller individual pixels (pixel pitch of 3.91μm versus 4.74μm for the E-510). Yet, the A5100 is a much more recent model (by 7 years and 5 months) than the E-510, 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 A5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5100 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-510 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 A5100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus E-510 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha A5100 are ISO 100 to ISO 25600 (no boost).

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.

E-510 versus A5100 MP

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 A5100 offers substantially better image quality than the E-510 (overall score 28 points higher). The advantage is based on 2.6 bits higher color depth, 2.7 EV in additional dynamic range, and 1.6 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.

One feature that differentiates the E-510 and the A5100 is in-body image stabilization (IBIS). The E-510 reduces the risk of handshake-induced blur with all attached lenses, while the A5100 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The A5100 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-510 does not have a selfie-screen.

The E-510 writes its imaging data to Compact Flash or xD Picture cards, while the A5100 uses SDXC or Memory Stick PRO Duo cards. The E-510 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A5100 only has one slot.

  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Longer lasting: Can take more shots (750 versus 400) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in March 2007).

ilogo

Arguments in favor of the Sony Alpha A5100:

  • More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
  • Better image quality: Scores substantially higher (28 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 (2.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 215k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (110x63mm vs 136x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 255g or 47 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More modern: Reflects 7 years and 5 months of technical progress since the E-510 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A5100 is the clear winner of the contest (21 : 6 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 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.

E-510 06:21 A5100

How about other alternatives? Do the specifications of the Olympus E-510 and the Sony A5100 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-510 or the A5100. 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

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 (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.

Care should be taken when interpreting the review scores above, 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 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.
