For my camera Nikon Coolpix S8200 I had initially the product Lowepro Rezo ordered me 30, because this should be the right product according to the website of the bag manufacturer. In this case the camera fit snugly and properly fed. Thanks to the circumferential bead the inside of the zipper, the camera can not damage it. However, you have to insert the camera already accurate enough so it slides into your pocket. From experience I know that this is a little more difficult when the bag hanging on the belt side. In addition, there could be even more closely, with some accessories in the front compartment located. For these reasons, I had the camera bag Lowepro Rezo ordered me an additional 50. In this the Nikon Coolpix S8200 is neat with plenty of game (top and side / total just over 1 cm) in the bag Lowepro Rezo 50. It would be best probably an intermediate size, which unfortunately no longer exists. Finally, I decided 50 camera bag for larger Lowepro Rezo. The smaller camera bag Lowepro Rezo 30 went back again.
The bags themselves: Both are very well made and worth the money anyway. Lustig is the extra for Velcro zipper on the Lowepro Rezo 50, which closes the compartment for accessories. This reminds me of the belt to the suspenders. ME totally unnecessary. The smaller camera bag Lowepro Rezo 30 does not have this zip; but just the velcro.
In short: The Lowepro Rezo 50 camera bag black top and worth the money.
