We just started testing cameras, and our test bench v0.7 is rather simplistic, so we decided to launch without text in the test boxes. If you have any suggestions on what to improve, let us know here. As we gather your suggestions, we plan on making more frequent changes to our methodology and we'll be able to add text to the reviews in the near future.

Olympus M.Zuiko Digital ED 14-42mm f/3.5-5.6 EZ

The Olympus OM-D E-M10 Mark IV is an entry-level mirrorless camera with a 20.3-megapixel Micro Four Thirds sensor. It's very lightweight and portable, and it has a tilting screen that can flip down to face you when holding it in a selfie position. It delivers impressive image quality with fantastic dynamic range and good noise handling capability. It has in-body image stabilization to reduce camera shake when shooting without a tripod, which works effectively, whether taking photos or shooting video. The camera also delivers great 4k video quality and satisfactory FHD video quality. However, its autofocus system is only decent, and it does a poor job tracking moving subjects in video and struggles to track faces when taking photos.

Our Verdict

7.6 Travel Photography

The Olympus OM-D E-M10 Mark IV is good for travel photography. It delivers impressive image quality and performs well even in low light. It's also very lightweight and portable, though it may be too small for those with very large hands. Its approximate advertised battery life is okay, though this can vary with settings and usage habits. The camera supports USB charging, but you can't use it while it charges. While its autofocus system is excellent at tracking moving objects, it struggles to track faces. It also isn't weather-sealed.

Pros
  • Lightweight and portable.
  • Impressive image quality.
  • In-body image stabilization.
Cons
  • Autofocus struggles to track moving faces.
  • Not weather-sealed.
7.8 Landscape Photography

The Olympus OM-D E-M10 Mark IV is good for landscape photography. Its image quality is great, and it has fantastic dynamic range to bring out more details in high-contrast landscape shots. It's also very portable, making it easy to take to remote shooting locations. It has a bright screen that can easily overcome glare in sunny conditions. However, its advertised battery life is only decent, and the camera isn't rated to be weather-sealed against elements like rain and humidity.

Pros
  • Lightweight and portable.
  • Impressive image quality.
  • Fantastic dynamic range.
Cons
  • Not weather-sealed.
7.6 Sport & Wildlife Photography

The Olympus OM-D E-M10 Mark IV is good for sports and wildlife photography. It delivers impressive image quality and feels comfortable to use. It also has a good continuous shooting speed that can capture photos at 10 fps in its high-speed drive mode and 15 fps in its silent mode using the electronic shutter. Its RAW image buffer isn't the largest, but thankfully, it has a quick buffer empty time, so it shouldn't slow you down too much. That said, its autofocus system struggles to track moving faces, though it performs significantly better when tracking objects.

Pros
  • Lightweight and portable.
  • Impressive image quality.
  • In-body image stabilization.
Cons
  • Autofocus struggles to track moving faces.
8.0 Vlogging

The Olympus OM-D E-M10 Mark IV is great for vlogging. It has a tilting screen that can flip down to face you. It's also very lightweight and portable for on-the-go vlogging. The screen can get in the way when using a tripod, so it's less suited to sit-down vlogging. It has in-body image stabilization, and it does an excellent job of reducing camera shake when walking, especially in FHD. Video quality is great in 4k and decent in FHD. However, its autofocus system struggles to track moving subjects in video, especially faces.

Pros
  • Lightweight and portable.
  • Screen can flip down to face you.
  • Great 4k video quality.
  • In-body image stabilization.
Cons
  • Autofocus struggles to track moving faces.
6.9 Studio Video

The Olympus OM-D E-M10 Mark IV is okay for studio video. It delivers great 4k video quality and decent FHD video quality, but its frame rate options are limited to 24 or 30 fps in either resolution. It can also be hard to find advanced settings since its menu system is confusingly laid out and hard to navigate. Unfortunately, it doesn't have a microphone or headphone jack, and its autofocus system struggles to track moving subjects.

Pros
  • Lightweight and portable.
  • Great 4k video quality.
Cons
  • Autofocus struggles to track moving faces.
  • No microphone or headphone jack.
5.2 Action Video

The Olympus OM-D E-M10 Mark IV isn't well-suited to action video. While it's relatively portable, it isn't designed to mount on a helmet or other action cam rig. It also isn't rated to be water-resistant. Its frame rate options are limited to 24 or 30 fps, so it isn't well-suited to capturing fast action smoothly. On the upside, it has in-body image stabilization, which effectively reduces camera shake when shooting without a tripod.

Pros
  • Lightweight and portable.
  • Great 4k video quality.
  • In-body image stabilization.
Cons
  • Autofocus struggles to track moving faces.
  • Not waterproof.
  • Limited frame rate options.
  • Not designed for action video mounts.

  • Suitable for most hand sizes but may be too small for those with extra large hands to hold comfortably
  • Handgrip is shallow and not as well texturized as some other cameras
  • Back thumb rest feels very comfortable
  • Easy to adjust settings like aperture, shutter speed, and ISO when looking through the viewfinder with your right eye
  • Eye cup feels okay
  • D-pad on back to navigate menu, but placement may be a bit awkward for larger hands
  • Screen can flip all the way down to face you, but it's almost impossible to use it with a tripod in this configuration
  • Can't access battery/SD card compartment when mounted on a tripod

  • Menu system is acceptable, with more advanced settings buried in the cog icon menu, which you can see here, here, and here, though it's simpler to navigate than the Olympus OM-D E-M5 Mark III
  • The quick menu is haphazardly organized, but it does consist of many commonly used settings
  • Useful guide mode that explains certain settings and features
  • Navigating using the D-pad feels intuitive
  • Some of the buttons are customizable, so you don't need to navigate the menu all the time

Differences Between Sizes And Variants

The Olympus E-M10 Mark IV comes in two color variants: 'Black' and 'Silver'. We tested the black version bundled with the Olympus M.Zuiko Digital ED 14-42mm f/3.5-5.6 EZ lens, but you can also buy it without a kit lens.

Let us know if you come across a different variant or your Olympus E-M10 Mark IV doesn't correspond to our review, and we'll update it.
