This pocket is typical of Kata, quality workmanship and well padded. Inside is an additional small compartment for another memory card. On the back is a belt buckle that has no Velcro. This has the advantage that the bag is slightly slimmer than pockets of "klettbaren" solution, however, has the disadvantage that you have to open the belt every time and pull through the buckle. I personally do not care, because I basically do not wear bags on the belt, for other users but could be important. Top right is, is not difficult to recognize on the product images, an additional loop that since it is likely to hold the bag securely in your hand. I think this feature is not really need, but it does not bother me. On the top there is a small metal eye where an included nylon / neoprene cord is attached, as a kind of strap. The term belt would be an exaggeration to about 4mm thick string, but it is comfortable to wear and definitely stable enough to bear the weight of a compact camera. The cord can be removed or adjusted by a cord stopper also.
In summary, the ZP-4 DL is a good bag that is optically relatively ok for my taste in its simplicity. Normally I would have given this 5 stars.
Now to the problem: the measurements given here on Amazon relate what is not specified, the internal dimensions. Therefore, I checked on the website of Kata. There, these dimensions are clearly marked as internal dimensions, which is completely false. 4.5 x 7 x 12.5 cm are only the external dimensions. The inner dimensions are much smaller, which is why my camera (11.1 x 6.4 x 4.0 cm) not even begin to fits. Even for smaller Coolpix P340, and probably also for a Canon PowerShot S120, the pocket is close. I therefore send the ZP-4 DL back and ordered the Kata ZP-6 DL, and hope this fits then.
Now there is the company Kata unfortunately anyway no longer, or was bought by Manfrotto, which some bags be produced in a similar form. This or a similar bag in any case can not be found on the homepage of Manfrotto. Therefore, these are probably a remaining inventory. Who is looking for such a case, and / or one of the last Kata bags, is right here. Provided, of course, to order the bag one or two sizes larger. ;)
