Canon 850D vs Olympus E-M10 IV

The Canon EOS 850D (called Canon T8i in some regions) and the Olympus OM-D E-M10 Mark IV are two digital cameras that were revealed to the public, respectively, in February 2020 and August 2020. The 850D is a DSLR, while the E-M10 IV is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (850D) and a Four Thirds (E-M10 IV) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 20.2 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 Canon 850D and the Olympus E-M10 IV is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

The E-M10 IV can be obtained in two different colors (black, silver), while the 850D is only available in black.

Compare 850D versus E-M10 IV top
Comparison 850D or E-M10 IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 IV is notably smaller (24 percent) than the Canon 850D. Moreover, the E-M10 IV is markedly lighter (26 percent) than the 850D. In this context, it is worth noting that neither the 850D nor the E-M10 IV 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 Canon EF Lens Catalog (850D) and the Micro Four Thirds Lens Catalog (E-M10 IV). Mirrorless cameras, such as the E-M10 IV, 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 850D gets 800 shots out of its Canon LP-E17 battery, while the E-M10 IV can take 360 images on a single charge of its Olympus BLS-50 power pack. The power pack in the E-M10 IV 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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-M10 IV was somewhat cheaper (by 7 percent) than the 850D at launch, but both cameras fall into the same price category. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 Canon 850D features an APS-C sensor and the Olympus E-M10 IV a Four Thirds sensor. The sensor area in the E-M10 IV is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 850D has a native 3:2 aspect ratio, while the one in the E-M10 IV offers a 4:3 aspect.

Canon 850D and Olympus E-M10 IV sensor measures

With 24MP, the 850D offers a higher resolution than the E-M10 IV (20.2MP), but the 850D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 3.34μm for the E-M10 IV) due to its larger sensor. However, the E-M10 IV is a somewhat more recent model (by 5 months) than the 850D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M10 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 850D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 850D 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-M10 IV are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The 850D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 850D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus OM-D E-M10 Mark IV are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

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.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M10 IV provides a faster frame rate than the 850D. It can shoot movie footage at 4K/30p, while the Canon is limited to 4K/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 IV has an electronic viewfinder (2360k dots), while the 850D 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 E-M10 IV offers a wider field of view (100%) than the one in the 850D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M10 IV has a higher magnification (0.62x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 850D, the Olympus E-M10 IV, and comparable cameras.

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

One feature that differentiates the E-M10 IV and the 850D is in-body image stabilization (IBIS). The E-M10 IV reduces the risk of handshake-induced blur with all attached lenses, while the 850D offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 IV 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 Canon 850D and the Olympus E-M10 IV 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 850D and the E-M10 IV write their files to SDXC cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 850D can use UHS-I cards (up to 104 MB/s).

It is notable that the 850D has a microphone port, which is missing on the E-M10 IV. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the 850D has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the 850D from Canon. Further information on the features and operation of the 850D and E-M10 IV can be found, respectively, in the Canon 850D Manual (free pdf) or the online Olympus E-M10 IV Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 850D and the Olympus E-M10 IV? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS 850D:

  • More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Can take more shots (800 versus 360) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2020).

ilogo

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

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (4K/30p versus 4K/24p).
  • 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 (0.62x vs 0.51x).
  • Faster burst: Shoots at higher frequency (15 vs 7.5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (122x84mm vs 131x103mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 132g or 26 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 IV emerges as the winner of the match-up (14 : 12 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.

850D 12:14 E-M10 IV

How about other alternatives? Do the specifications of the Canon 850D and the Olympus E-M10 IV 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 incomplete and does no justice, for example, to the way the 850D or the E-M10 IV perform in practice. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
