The dissimilarity between DSLR, which so much loved by most adepts, and DSLM or EVIL (these are two short names for mirrorless cams) is in the lack of a mirror in the last one. DSLR’s mirror reflects light arriving in the lens up to a prism or other mirrors. Then the reflection is transmitted to the viewfinder. This permits previewing your shot. After you push the button to take a picture, the light finally gets to the image sensor, which creates the final image. DSLM camera functions a bit differently. The light is being transferred through the lens straight to the sensor. The last one seizes a preview and demonstrates the picture on display. Thus, at the very end, you obtain equal photo and video quality in both types of devices. Apart from that, a mirrorless cam is more suitable for YouTube blogging due to the absence of a mirror. It means less camera shaking. And yes, in this case, the camera body is considerably smaller and lighter.

So, what is the best mirrorless camera for video? Well, most of the models are appropriate for video and photo blogging. However, consider the weight of the device as it should be portable. Check if you can connect lenses without any extra stuff like adapters. Be sure that the autofocus is what you need for recording your mini-movies or blogging clips. Else, if you keep reading the article you will find several top-notch camera suggestions. The cams on our list are what you need. Check them out and you save lots of time on searching a good model on the web.

Mirrorless –°ameras Have the Best Autofocus for Shooting Video

Even a beginner mirrorless camera autofocus is not worse than the one of DSLR. You will be surprised, but it is even much better. Why? It allows you not only to switch between the AF preset modes but also make some manual adjustments as well as to control the depth of field via the aperture. This is so much more in handy for creativity and stuff, isn’t it? Do not hesitate to use AF when you record a video with a mirrorless cam. For example, when you are shooting yourself or for the vlog on the go, it is better to use autofocusing than manual control as it takes less time and easily adjustable with a tap on LCD. Face and eye detection function guarantee that you have the sharpest and the clearest image possible. Also, be sure to use your DSLM AF when you are filming with a gimbal. Usually, a gimbal gives you remote control over the main camera functions so you can adjust focusing without interrupting your video and touching the screen.

Mirrorless cameras, unlike DSLRs, work using contrast detection. It calculates and evaluates the contrast between pixels on the sensor. When it spots sufficient contrast, it finds the focus on the image. This focusing method has some disadvantages. It is slower than the one in DSLR (normally, it is hardly noticeable). It needs lots of light, which can cause problems when you shoot in faint light. And, unfortunately, it is more efficient with the motionless image, and there is a myth that it is a bit harder to focus on moving objects with a mirrorless camera. This is true only for photos. If we are speaking of recording some YouTube clips, you will feel that this sort of cam overpasses DSLR or point-and-shoot cams. DSLRs utilize the same contrast-detection focusing for video shootings, but since DSLM cameras utilize more flexible and sophisticated technologies they are commonly more responsive and refined.

Aaaand the question is, which mirrorless camera has the best autofocus for shooting video? Scroll down for our list of the best mirrorless cameras for video autofocus to get some good examples.
