How to Buy a Full-Frame Mirrorless Camera?

We have already discussed the best full-frame mirrorless cameras for your convenience. You can buy any of these cameras without giving it a second thought according to your requirements and budgets. However, we are going to explain a few points you need to keep in mind while buying a full-frame mirrorless camera.

Lens Compatibility

Sony has been making full-frame mirrorless cameras for 8 years now. Therefore, it has a wide range of compatible lenses for its cameras as well. Mirrorless full-frame cameras from other companies including Canon are relatively newer. As a result, they may have a limited range of compatible lenses and accessories. It is worth checking what you are currently getting and what will be available in the future.

It is pertinent to mention that most Canon full-frame cameras including the Mirrorless cameras are compatible with EF lenses. You can use the older EF lenses on mirrorless cameras using an adapter. Similarly, you can always use the newer EF lenses on Canon’s mirrorless cameras a well.

Burst Rate

You should buy a Canon EOS full-frame mirrorless camera with a high burst rate if you capture images frequently. Similarly, you must also look for the burst depth. There is a bit of difference between the two terms. The burst rate means how many images you can take per second. The burst depth, on the other hand, determines how long you can keep shooting. Also, look out for the continuous focus because it can decrease both burst rate and depth.

Buy a Low-Resolution Camera for Videos

If you are buying the best Canon full-frame mirrorless camera primarily for videos, make sure it has low resolutions instead of high pixel count. It is also imperative to check for headphone and microphone ports, and other shooting options such as frame rate, at least 4K video resolution, and low light performance.

Miscellaneous Features

Not to mention, you must go for a camera with Dual Pixel CMOS autofocus, high autofocus points, an electronic viewfinder, and an articulating touchscreen. Similarly, some electronic viewfinders are larger than others. Some LCD screens only swivel, some tilt, some do both, and some do nothing. However, almost all of them are touchscreens, necessary for setting the focus points and other things.

Final Thought

With this, we conclude our guide to the best Canon mirrorless full-frame camera. Mirrorless cameras have taken the camera industry by storm. It is high time you also bid farewell to your current camera and get on the mirrorless bandwagon if you haven’t already. Otherwise, you will be left behind and found wanting in this highly competitive profession.
