I buy this cover for Sony HX50. The size is perfect! The locking system allows you to take and store the device quickly. My only complaint was that the strap is too fine and could be better. Regarding the comments of other people about the loop to get the belt and although there is no problem, you just pass it inside his belt, the system actually closes with a snap but if it detaches your belt holds the cover because it happens in a loop. Believe me people arriving to lose this cover not have been able to tie properly, I recommend it.
