micro four thirds vs aps c

When shopping for a camera, you’ll find that there are a lot of specs to consider. One of the most crucial ones is the integrated type of sensor.

There’s no doubt choosing between Micro Four Thirds vs APS C sensors can make a significant difference in your shooting.

With the ability to affect how your camera behaves and how you should handle it, consider comparing Micro Four Thirds (MFT) compared to APS C.

This guide will review both sensor types to help you choose the perfect rig for your professional or amateur photography.

What To Know About Camera Sensors

When you read the term “camera sensor,” it refers to a piece of hardware inside your camera.

A sensor is responsible for gathering light in your environment, converting it to the images you’ll see on the screen.

Typically, these sensors have millions of spots sensitive to light, making it easier to record what you see through your lens.

There are multiple aspects of capturing images that your camera sensor can affect, including:

  • Camera Size: Interestingly, the size of your camera sensor will affect the physical size of your camera. As mentioned, larger sensors also mean a larger camera body, essential to note for travel.
  • Image Resolution and Quality: Resolution and quality are relatively self-explanatory and are expressed in megapixels when talking about cameras. Traditionally, the larger the sensor, the more megapixels you’ll have.
  • Angle of View: Your angle of view is the amount of frame you see once your pictures have been taken. Using a lens with a full-frame large sensor will allow you to have a larger angle of view.
  • Low-Light Performance: Shooting in low light can be a hassle without a quality camera. You may find shooting in low light is easier than with a small sensor with a larger sensor.
  • Depth of Field: With the depth of field, your focal point pop by blurring the background. Photographers often prefer large sensors to access this feature, as smaller sensors need more distance for a blurred background.

What Are the Different Types of Camera Sensors?

There are five standard camera sensors you’re likely to find in your chosen digital cameras. In this guide, we’re focusing on Micro Four Thirds compared to APS C, but there are three others to note as well, including:

Full Frame (36mm x 24mm)

Full frame sensors are typically the fan-favorite as they are the largest.

You’ll find their capturing capabilities are similar to that of a 35mm camera, and they have zero crop factor.

Everything you see in the viewfinder translates directly into your photos when you shoot with a full-frame sensor.

You’ll find cameras with full-frame systems will be the largest and bulkiest. You’ll also find the lenses they need are bound to be considerably larger.

APS-H (28.7mm x 19mm)

If you’re in the market for an interchangeable lens camera, you’ll likely find an APS (Active Pixel Sensor).

With APS-H, you combine an average-level pixel count paired with a larger sensor. These cameras will also have a more extensive ISO performance and 1.3x crop factors.

One-Inch Sensor

Aside from APS-C and MFT, a one-inch sensor is the last option you’re likely to come across. It’s the smallest out of this list, although there are sensors that can go even smaller.

One-inch sensors are typically between 13.2mm and 8mm combined with a 2.7x crop factor.

Micro Four Thirds

If you’re on the hunt for a Micro Four Thirds camera, you’ll be straying far away from DSLRs, as these cameras are mirrorless.

With that said, many of these cameras featured MFT at the emergence of DSLRs, but post-2008 models were mirrorless.

When shooting with Micro Four Thirds cameras, you’ll have a 17.3mm x 13.0mm sensor size, similar to 110 Kodak cartridge film.

As expected, the aspect ratio of MFT is 4:3, which is the standard ratio for medium formats. This ratio is best for making prints, especially if you want to use standard sizes like 6 x 4.5 inches.

You’ll need to note a few numerous things regarding this sensor type, such as:

  • Body Size

Cameras that feature MFT sensors are slightly smaller than your average DSLR. That is because the lens mount and sensor have limited spacing, reducing the camera body size.

They’re an excellent travel solution, especially if you’re heading on a plane.

  • Lens Compatibility

You’ll undoubtedly want to switch between different lens types when capturing different subjects. For example, telescopic lenses can be helpful for nature photography, while macro lenses are best for detailed shots.

With Micro Four Thirds cameras, you’ll find they have wide compatibility with interchangeable lenses. In fact, you’ll even find that you can use third-party lenses with most cameras with compatible adapters.

This feature can help you save plenty of money instead of settling for manufacturer-specific utilities.

The lens size is another massive cost saving you’ll experience with this sensor type. Instead of investing in costly, large lenses, MFT cameras work with smaller and shorter lenses.

You’ll still have access to the same focal length, but as fewer materials are needed to make smaller lenses, they’re more affordable.

  • Reduced Noise

As mentioned, the physical sensor inside MFT cameras is considerably smaller than with APS C cameras. With their smaller size, you’ll find they also generate less heat, making it easier for the camera to operate seamlessly.

This feature is important to note if you prefer long exposure shots, as you’ll have less noise with seamless shooting.

  • Depth of Field

Compared to APS C cameras, you’ll find a considerable difference with Micro Four Thirds cameras in their depth of field.

While APS C models are better for portraits, MFT cameras are remarkable for nature and landscape photography. With its higher depth of field, you’ll capture even more activity in a larger frame, even without a tripod.

  • Video Performance

With the consistent upgrades to photography tech, most, if not all, cameras can capture photos and videos.

If you’re hunting for a camera with awesome video capturing capabilities, MFT is a top-tier solution.

Its impressive video performance makes it an excellent choice for capturing high-quality videos in low and bright light conditions.

  • Battery Consumption

One of the more considerable downsides to MFT sensors is that they consume more battery power than other sensors.

With that said, you must always carry a spare battery with you, especially when shooting for extended periods of time.

  • Electronic Viewfinders

If you’re someone who prefers to use a modernized viewfinder, Micro Four Thirds cameras are your best bet. However, if you’re preferential to optical viewfinders, it’s better to opt for APS-C models, as these cameras only have electronic viewfinders.

  • Limited Manufacturers

The most restrictive disadvantage to cameras with MFT sensors is that very few manufacturers make them. In fact, the two notable companies you’ll have to choose from are Panasonic and Olympus.

Unfortunately, this considerably limits your possibilities when finding the perfect camera for your needs.
