A few months back we discussed the pros and cons of mirrorless cameras vs DSLRs. Here are a few notes and helpful links from that discussion.
Mirrorless vs. DSLR cameras:
Mirrorless vs DSLR
A DSLR camera is a digital camera body that allows light to enter a single lens where it hits a mirror that reflects the light either upwards or downward into the camera’s optical viewfinder (OVF). DSLR stands for Digital Single-Lens Reflex.
When you press down on the shutter, the mirror flips up out of the way. The shutter then slides open, and light coming from the lens takes a straight shot to the imaging sensor where a photograph is made.
A mirrorless camera is a digital camera that doesn’t have a reflex mirror. In a mirrorless, there isn’t an optical viewfinder and the imaging sensor is always exposed to light. It gives you a preview of the image on the electronic viewfinder (EVF), which is often an LCD screen on the back of the camera.

Pros of DSLRs
Better battery life (though this is narrowing)
Larger lens selection
Faster autofocus (generally, although also narrowing)
Cons of DSLRs
Big and bulky
Slower shooting speeds
DSLRs offer 4k or Ultra HD video only for higher-end models.
Pros of Mirrorless Cameras
Light, small and compact
Less moving parts, they’re quieter than other cameras
No flicking mirror means no camera shake
Reliable video mode
The electronic viewfinder can be used in video mode, while the viewfinder on a DSLR cannot. Also, high resolution is built into most mirrorless even if they’re on the low-end, quality wise.
Cons of Mirrorless
Battery life (though getting better! See more on this below)
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
Here are some of the mirrorless cameras that we mentioned during the discussion by artists Nanci Frace-Vaz and Slade Wheeler:
