Best Rated Mirrorless & 4K Compact Interchangeable Lens Cameras | Comparison and Reviews 2020

APS-C Imager = This imager is smaller than a Full Frame imager, but bigger than a Four Thirds Imager. Lenses used on SLRs with APS-C imagers have a focal length about 1.5x that of full frame imagers (crop factor 1.5). This means that the telephoto end of the lens will be greater. New digital lenses have been developed for these type of mirrorless cameras.
Four Thirds Imager = This imager is smaller than a Full Frame imager. Lenses used on SLRs with Micro Four Thirds imagers have a focal length 2.0x that of full frame imagers (crop factor of 2). This means that the telephoto end of the lens will be greater. New digital lenses have been developed for these type of mirrorless cameras.
Crop Factor = This refers to how the focal length of the lens will behave compared to the same lens on a camera with a full frame 35mm sized imager. A crop factor of 2.0 means that a 16mm lens will behave like a 32mm lens. The higher the crop factor, the larger the focal length and also the telephoto end of the lens.
ISO = This refers to how sensitive the image sensor is to the amount of light present. The higher the ISO, the more sensitive the image sensor and ability to take pictures in low-light situations. EXT ISO is the extended mode.
Live View = Allows you to preview your picture on the LCD screen instead of only through the viewfinder. All current models have this feature.
Movie Frame Rates = This is how many pictures (or frames) can be taken rapid fire per second at maximum resolution for video. So, 1080/24/60P HD will shoot 24 and 60 progressive frames/second at full HD 1080p.
HD Movie Mode = These sub-compact cameras can operate as an HD camcorder as well as an SLR. We also list the resolution (4K Ultra HD, 1080p, 1080i and 720p) that each camera is capable of recording.
In Body and 5 Axis Stabilization = Select Sony models (a6500, a7s II, a7r II, a7 II) and Panasonic Models (GH5 & GX85) have In Body stabilization. This is also referred to 5 axis stabilization if used with an image stabilized lens. If you use a non IS lens, you still will benefit from the Image stabilization in the body of the camera.
S-Log2 Gamma and S-Log3 Gamma = Users can adjust the gamma, black level, color level, and more dynamic range. Allows you to capture a much wider brightness range.
Compact E-mount = This refers to the lens mount that the Sony Alpha cameras use for their mirrorless interchangeable lens system cameras.
Micro Four Thirds mount = This refers to the lens mount that the mirrorless cameras that Panasonic Lumix and Olympus Pen cameras use.
LCD = This refers to the LCD screen in the back of the camera. A tiltable screen allows you to take pictures above your head or down low. A flip up screen or fully articulating screen will also allow you to do selfies.
Detachable Flash = On some Sony Cameras, the flash is not built-in (such as the full frame Sony alpha models), but clips on to the accessory shoe when you need it.
Weight and Dimensions = The weight and dimensions listed are for the camera body only.
