What lenses should I buy for the om system om 1?

For an everyday kit on the OM-1, I'd start with the OM System M.Zuiko 12-40mm f/2.8 PRO II. It frames like 24-80mm on full frame, and that constant f/2.8 keeps it useful indoors.

Then add one lens for what you shoot most:

If you're not sure yet, buy the zoom first and let your shooting tell you what to add. The focal length converter helps if you want to check any other lens against full frame.
