49mm lens cap compatibility with 49mm filter

[g_khajanchi]

Hello Team,

Can a Canon 49mm lens cap be used on the Canon Filter Protect 49mm when the camera is not being used for work?

Typically a lens cap for a lens that takes a given size of filter will also work on most filters attached to the lens.  There are exceptions like when you are using square filters.
