Good protection, Great Place - but little mobility

Personally, I was in the inside pocket of my Defender Body (Canon 500D) with an attached lens and my second lens to accommodate (once Canon 18-135mm Canon 70-300mm and once with each matching lens hood). Transported to the body and the lenses separately and individually, could be a third, depending on the size also accommodate a fourth lens without any problems.
With the two large and two small Velcro dividers can be the interior of the bag and individually divide. In addition still found the manual, provided cables and the charger in the inside pocket of space - for the simple reason that the forwardmost accessory compartments are designed in my opinion too tight and could have been there, the accessories have to cram in order to then still close the zipper can ,

Also a plus is the good protection and good processing that provides the pocket. The interior is padded with thick, soft fleece and protects the contents from knocks.
What is somewhat misleading in the photo: The inside pocket can be independent of the two clip closures front open a sturdy zipper. The clip closures front are just an additional closure of accessory pockets.

The supplied and also anklettbare microfiber cleaning cloth is a nice gimmick, but more really. The included case-pocket for memory cards, a lot of small carabiner and the rain cover is in my opinion a nice-to-have, but also takes space. The exact interior and exterior dimensions are in the product description here at Amazon.
Although belt buckles are available, I would not attach the bag because of its size on the belt and I doubt if this is at all possible with "normal-wide" people.

The great advantage of the bag, really accommodate everything is, of course, also the main drawback: the really small bag is not.
On photo tours, for example on walks, I would not like to constantly have to carry around with me - because change also ergonomically shaped straps nothing. I trust in the fall rather on a small shoulder bag and an additional belt pouch for the interchangeable lens, both of which can be accommodated in a smaller backpack. In the Defender 140, this is not possible.
But in my opinion it is very suitable for people who only want to carry the camera equipment from A to B, without it distributed among several bags. To mention here is the compatability of the lens quivers Defender of Hama. These can be securely attached to the loops on the sides of the Defender-pocket and easily installed.

Conclusion:
The bag is really good to bring a lot of equipment in a bag from A to B and offers a lot of individual possibilities to divide the space.
Less well it is my opinion for mobile use on photo tours because it is too large.

Here one must, however, assess what is important for a: Everything For maximum protection in a pocket or whilst having quick and easy, convenient access to camera and / or additional lenses to have.
