GearScore™ Verdict — Which should you buy?
Commercial, Studio & Landscape Photography — GFX 100 (2019): The world's first 100MP mirrorless with IBIS and phase-detect AF — the GFX 100 was a landmark in medium format, but its size and weight are professional-grade.
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
GFX 100 (2019)
- Commercial and advertising photographers who need extraordinary resolution
- Landscape photographers willing to carry a large body for maximum detail
- GFX system users who want the original 100MP body at a lower cost than GFX 100S
- Studio photographers who want the finest image quality the GFX system can offer
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
- Travel shooters who want a rugged, lightweight MFT system
- OM-5 or E-M5 III owners wanting better autofocus without going to the OM-1
