Which should you buy?
Entry-Level Full-Frame & Dslr Switchers — Z5 (2020): The most affordable route into full-frame Z — dual card slots, IBIS, and a capable sensor at an accessible price.
Travel, Outdoor & Adventure Photography — OM-3 (2024): The ideal mid-range OM System camera — weather sealed, class-leading IBIS, and superb computational features in a compact body.
Who should buy what
Z5 (2020)
- DSLR photographers switching to full-frame mirrorless for the first time
- Enthusiasts who want full-frame image quality on a tighter budget

OM-3 (2024)
- Outdoor and adventure photographers who need weather sealing and compact size
- Wildlife and bird photographers wanting improved AF over the OM-5
