Mirrorless Cameras Are Extremely Refined Because Of Inherent Technology
Mirrorless cameras are smaller, lighter, and quieter than DSLR models. There is no mirror, which allows street, theater, and wedding photographers to shoot almost without being seen. However, choosing an appropriate one needs to consider lens system to sensor size to video capabilities and more.
Mirrorless cameras include interchangeable lenses, which differentiates it from others. With interchangeable cameras selective focus gets highlighted, which is noticeable. With no mirror in front of the sensors, you have option to capture images with prime portrait lens having f/1.4 aperture or long zoom lens having f/2.8 aperture.
Various size sensors are available in mirrorless cameras. DSL cameras are equipped with APS-C sensor, which is largest and compact point & shoot have small size sensors, but there is the micro 4/3rd sensor in between these two. If low light camera work is your forte than consider full frame mirrorless cameras (large sensors) because it works best in low light otherwise a small size micro 4/3rd s is a good fit.
An optical through-the-lens (TTL) viewfinder means you see exactly what the lens views. As there is no mirror for directing the lens view to viewfinder, an EVF (electronic viewfinder) is used in majority of mirrorless cameras. EVF technology has a disadvantage just like optical TTF viewfinder and that is the lag time of something actually in motion and seen on EVF. Another thing to consider is that EVF uses a lot of battery power, which is not a big concern. EVF gives accurate portrayal of exposure, color stability, or adjustments before clicking.
Contrast detection is used to measure distinction between pixels until sufficient contrast is detected of the image in focus. Today, you need to look at hybrid autofocus system, which blends contrast detection and phase for better images in low light.

Mirrorless cameras provide flexibility for video recording in regards to lenses and shoot full HD and even 4K. Due to in-built technology mirrorless cameras are more refined as well as responsive.
