FAQs

Should I buy a DSLR or mirrorless in 2026?

For most people, mirrorless. Better autofocus, video, and smaller bodies. Consider DSLR only if you already have lots of DSLR lenses or need very long battery life.

Can I use my old DSLR lenses on mirrorless?

Yes, with adapters. Canon EF to RF, Nikon F to Z, and Sony A to E adapters let you use existing lenses; autofocus performance varies by adapter and body.

Do mirrorless cameras have worse battery life?

Generally yes — the EVF and screen use more power. Carrying a spare battery is normal; many mirrorless bodies now get 400–700 shots per charge.
