MILC vs. DSLR Camera: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on February 17, 2024
MILC (Mirrorless Interchangeable Lens Camera) lacks a mirror mechanism, enabling compact design; DSLR (Digital Single-Lens Reflex) uses a mirror for an optical viewfinder, typically larger and heavier.

Key Differences

MILC, being mirrorless, is more compact and lighter than a DSLR. The absence of a mirror mechanism in MILCs allows for a smaller body, whereas DSLRs, with their mirror and prism system, are generally bulkier.
MILCs use an electronic viewfinder (EVF) or LCD screen for image composition. DSLRs, however, rely on an optical viewfinder (OVF) using a mirror and prism system, providing a direct optical view through the lens.
MILCs often have faster autofocus systems using on-sensor phase detection, advantageous in video and rapid shooting. DSLRs traditionally used separate autofocus sensors, though newer models are closing this gap.
DSLRs typically offer longer battery life due to the lower power consumption of optical viewfinders. MILCs, with electronic viewfinders and screens, usually consume more power, leading to shorter battery life.
DSLRs, established for longer, have a wider range of available lenses. MILCs are catching up but may have fewer native lens options, although adapters can expand their compatibility.
