Should I switch from the canon eos 850d to mirrorless?

I'd only switch if the DSLR is holding you back. The 850D is a capable APS-C camera, and its 24.1-megapixel sensor is plenty for most work. Its specs list no in-body stabilisation, so slow shutter speeds rely on stabilised lenses. If that's a problem, check your lenses first.

Mirrorless has real advantages. You see the exposure before you shoot, and autofocus can find and follow eyes. Most new lenses are going into mirrorless mounts, and cheap old manual lenses adapt easily. The first camera guide explains the reasoning. Also check the sensor sizes page, since APS-C stays the same size in either system.

Your Canon EOS 850D page lists every lens that fits it. Before you buy anything new, make sure the lenses you own will work with the body you're considering.
