Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark II and the Olympus Stylus 1? 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-M10 II and the Olympus Stylus 1. 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.

The E-M10 II can be obtained in three different colors (black, silver, brown), while the Stylus 1 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus Stylus 1 is somewhat larger (1 percent) than the Olympus E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the Stylus 1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Stylus 1 has a lens built in, whereas the E-M10 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M10 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 II gets 320 shots out of its Olympus BLS-50 battery, while the Stylus 1 can take 410 images on a single charge of its Olympus BLS-5 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M10 II features a Four Thirds sensor and the Olympus Stylus 1 a 1/1.7-inch sensor. The sensor area in the Stylus 1 is 81 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 4.5. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of chip-set technology, the E-M10 II uses a more advanced image processing engine (TruePic VII) than the Stylus 1 (TruePic VI), with benefits for noise reduction, color accuracy, and processing speed.

With 15.9MP, the E-M10 II offers a higher resolution than the Stylus 1 (11.8MP), but the E-M10 II nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.91μm for the Stylus 1) due to its larger sensor. Moreover, the E-M10 II is a somewhat more recent model (by 1 year and 9 months) than the Stylus 1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Olympus E-M10 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 II for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Olympus Stylus 1 are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 cm for excellent quality prints.

The Olympus OM-D E-M10 Mark II 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 Olympus Stylus 1 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the E-M10 II is build around a CMOS sensor, while the Stylus 1 uses a BSI-CMOS imager. 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 review, the E-M10 II provides substantially higher image quality than the Stylus 1, with an overall score that is 22 points higher. This advantage is based on 2.4 bits higher color depth, 0.9 EV in additional dynamic range, and 2.2 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M10 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M10 II and the Olympus Stylus 1 both have 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.

Concerning the storage of imaging data, both the E-M10 II and the Stylus 1 write their files to SDXC cards. The E-M10 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Stylus 1 cannot take advantage of Ultra High Speed SD cards.

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 OM-D E-M10 Mark II and Olympus Stylus 1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-M10 II and the Stylus 1 have been discontinued, but can regularly be found used on ebay. The Stylus 1 was replaced by the Olympus Stylus 1s, while the E-M10 II was followed by the Olympus E-M10 III. Further information on the features and operation of the E-M10 II and Stylus 1 can be found, respectively, in the Olympus E-M10 II Manual (free pdf) or the online Olympus Stylus 1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M10 II or the Olympus Stylus 1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Olympus OM-D E-M10 Mark II:

• More detail: Offers more megapixels (15.9 vs 11.8MP) with a 16% higher linear resolution.
• Better image quality: Scores substantially higher (22 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.4 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.2 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (TruePic VII vs TruePic VI).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.58x).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 7 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Is somewhat more recent (announced 1 year and 9 months after the Stylus 1).

Arguments in favor of the Olympus Stylus 1:

• Ready to shoot: Has an integrated lens, whereas the E-M10 II necessitates an extra lens.
• Longer lasting: Gets more shots (410 versus 320) out of a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in October 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 II is the clear winner of the match-up (15 : 3 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-M10 II and the Olympus Stylus 1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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-M10 II and the Stylus 1 in practical situations. 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 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
