Olympus E-M5 vs YI M1
The Olympus OM-D E-M5 and the YI M1 are two digital cameras that were announced, respectively, in February 2012 and September 2016. Both the E-M5 and the M1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 15.9 megapixels, whereas the YI provides 20.2 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 OM-D E-M5 and the YI M1? 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-M5 and the YI M1. 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 measures are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the YI M1 is considerably smaller (33 percent) than the Olympus E-M5. Moreover, the M1 is markedly lighter (34 percent) than the E-M5. It is worth mentioning in this context that the E-M5 is splash and dust resistant, while the M1 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
Concerning battery life, the E-M5 gets 360 shots out of its Olympus BLN-1 battery, while the M1 can take 450 images on a single charge of its YI BXM-10 power pack. The power pack in the M1 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M1 was launched at a markedly lower price (by 73 percent) than the E-M5, 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.
Sensor comparison
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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
While the two cameras under review share the same sensor size, the M1 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the E-M5. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the M1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.76μm for the E-M5). However, it should be noted that the M1 is much more recent (by 4 years and 7 months) than the E-M5, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The resolution advantage of the YI M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M1 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Olympus E-M5 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Olympus OM-D E-M5 has a native sensitivity range from ISO 200 to ISO 25600. The corresponding ISO settings for the YI M1 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the M1 provides a better video resolution than the E-M5. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60i.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Olympus E-M5, the YI M1, and comparable cameras.

One feature that differentiates the E-M5 and the M1 is in-body image stabilization (IBIS). The E-M5 reduces the risk of handshake-induced blur with all attached lenses, while the M1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The YI M1 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.
Concerning the storage of imaging data, both the E-M5 and the M1 write their files to SDXC cards. The E-M5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M1 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-M5 and YI M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-M5 does not provide wifi capability.
Both the E-M5 and the M1 have been discontinued, but can regularly be found used on ebay. The E-M5 was replaced by the Olympus E-M5 II, while the M1 does not have a direct successor. Further information on the features and operation of the E-M5 and M1 can be found, respectively, in the Olympus E-M5 Manual (free pdf) or the online YI M1 Manual.
Review summary
So what is the bottom line? Is the Olympus E-M5 better than the YI M1 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M5:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been available for much longer (launched in February 2012).
Arguments in favor of the YI M1:
- More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 610k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (114x64mm vs 122x89mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 144g or 34 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (450 versus 360) out of a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
- More modern: Reflects 4 years and 7 months of technical progress since the E-M5 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the M1 is the clear winner of the contest (12 : 7 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 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-M5 and the YI M1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M5 or the M1. 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 why hands-on reviews by experts are important. 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
