OM System OM-1 vs OM System OM-5

The bottom line

There's a real price gap here: the OM System OM-5 at $1,199 versus the OM System OM-1 at $2,199. The extra buys you faster 50fps burst and dual card slots. The question is whether those advantages are ones you'll use often enough to justify the premium — if not, the cheaper body is the smart buy.

Choose the OM System OM-1 if…

  • You shoot action, sports or wildlife — 50fps burst keeps up with fast, erratic movement where 30fps would drop frames.
  • You need backup-while-you-shoot reliability — dual card slots (the other has one) matter for paid work like weddings and events.

Choose the OM System OM-5 if…

  • You're budget-conscious — it launched at $1,199, about $1,000 less, freeing money for lenses.
  • You value portability — at 414g (14.6 oz) it's noticeably lighter than the 599g (1.32 lb) alternative for travel and all-day carry.

  • Card slots: the OM System OM-1 has dual slots for instant backup — the reliability paid work depends on.
  • Burst: the OM System OM-1 shoots 50fps to the OM System OM-5's 30fps — the gap that decides whether you nail the peak moment in sports and wildlife.
