Beautiful and very efficient lens with M52 thread.
Perfect for the Olympus Tough cameras. (TG-4 or TG-5)
This wetlens will fit straight on your 52mm thread on your housing - or even on your 67mm thread using the AD-52/67 adaptor. Easy and affordable!
The lens is made for cameras with a 24mm lens as the widest focal width.
But regular compact camera systems will also shine bright using it.
