Best Mirrorless Cameras in the UK – Top Picks for 2021

  • Whatever your budget or shooting style, our guide contains all of the top mirrorless cameras.

Mirrorless cameras have been gaining popularity over the past few years. This trend is continuing, and 2021 is going to be no different. Whereas the best mirrorless camera in 2021 in the UK is a difficult question to answer, but we’ve done our research and put together a list of some of the top picks for you!

Mirrorless cameras have various types. Some are smaller, more portable, more suited for a travel-savvy generation, and can make the most of emerging, lightweight technology. Many manufacturers are looking to develop their mirrorless lineups, and have invested hugely in the process, and each one of these manufacturers is generating quite a hefty sum due to it.

Attention: Are you looking for a new camera?

Mirrorless cameras have been around for a while now, but they’ve recently become more popular than ever. The reason is that mirrorless cameras are smaller and lighter than DSLRs, making them easier to carry around with you all the time. They also give you better image quality in low light conditions and offer superior autofocus performance. And because there’s no mirror inside, the viewfinder doesn’t black out during shooting which means it can keep up with fast-moving subjects like sports or wildlife photography. You can even use your smartphone as a remote control!

Compact camera vs mirrorless camera


  • Compact cameras and mirrorless cameras aren’t two different types of cameras. In fact, the term “compact cameras” can encompass some mirrorless cameras (the term “mirrorless” simply means not having a mirror in front of the camera sensor.)
  • The most preeminent added benefits of a mirrorless camera over a compact camera is lenses and the ability to switch lenses. This gives you a DSLR like the option in a much smaller package.

Either an APS-C sensor, which stands for Advanced Photo System – Classic image format.

Or a Micro Four Thirds sensor, which is 30 – 40% smaller than APS-C sensors, but a micro four-thirds sensor, which makes the mirrorless camera compatible with many ultra-telephoto lenses

  • Light, small and compact.
  • No flicking mirror means no camera shake.
  • Less moving parts, they’re quieter than other cameras.
  • Reliable video mode.
  • The electronic viewfinder can be used in video mode, while the viewfinder on a DSLR cannot. 
  • In-body stabilization
  • Battery life though getting better.
  • Ergonomics small, maybe too small for anyone with big hands.
  • Limited lens selection (again, getting better! But a fair point)
  • Electronic viewfinder – limited in low light environments.

How Does a Mirrorless Camera Work?

The mirrorless system is more straightforward than the DSLR. Instead of using a mirror to bounce light to the viewfinder and sensor, the sensor is instead directly exposed to light. This generates a live preview of your scene directly to the electronic viewfinder.

When the shutter button is pressed, a door slides up to cover the image sensor. The door will then slide down, exposing the sensor to light. After that, another door slides up to cover the sensor again, which stops exposure, taking the picture.

If you’re looking for the best mirrorless camera in 2021, then you’ve come to the right place!
