Unfortunately, there is for the Sony NEX-3NLB not many alternative bags what terms. Either it is the original Sony Pocket which precipitates much to large, or leather bags from China which, though the form accurately adjust but offer little protection. Here you have material with thick padding and the camera fits perfectly pure. There is also a small pocket for memory cards. Better a bag would like would be adapted to the shape of the camera to me. Above and below the lens is unnecessary air. I realize that this bag was designed not only for Sony, but that is not because it does not even get any better. The belt clip is a bit strange with your very Velcro.
