OM System LC-115 Lens Cap for M.Zuiko ED 150-400mm F4.5 TC1.25X IS PRO

The LC-115 caps the front of the M.Zuiko Digital ED 150-400mm F4.5 TC1.25X IS PRO. At 115mm across it is a substantial piece of moulded plastic in its own right, with a snap-on mechanism sized to hold securely on a lens that gets carried over rough ground.

Buying it separately is normally a replacement job, and it is worth doing promptly: a bare front element on a lens of this value is not a risk worth carrying for a season.
