Since I was looking for a packaging for quite space-saving team from my Sony NEX-6 and the 18-200'er Zoom which precipitates is not too bulky, I had decided for this neoprene case. They fit almost like a glove, even the sun visor can be left on the lens without the cover fits too tight. It is closed by a rear hook and loop fastener, which occupies almost the entire width. The shell can be secured by a tab on the strap of the camera.
I am satisfied with this envelope because me a "real" camera bag is too big and I use the zoom to travel just yet rumzutragen dozens of other lenses with me.
