If you hear the phrase “holy trinity” applied to photography, it means a selection of prime lenses with a wide, a standard, and a medium telephoto focal length. Depending on the type of photography you do, you may never need any other lens.
Olympus has just announced two new lenses that join the already shipping Olympus M.Zuiko Digital ED 25mm f/1.2 PRO Lens to form their new trinity.
