For the optics I have forgiven the 2 stars.
Now for the not-awarded 3 stars:
The interface makes on me in any way a quality impression, I had the feeling that a leather-like, thin material has been glued to a cardboard.
Inside the envelope is indeed padded, but acts at the diffusion also here not so, as I am waiting for a least 70 expensive casing.
The zippers also make a rather minderwetigen impression and I was afraid that the expensive content is scratched during opening and closing.
The result for me a 2 star rating.
Unfortunately, the Hammer optics holds not what I imagine to functionality.
I have the bag immediately sent back and I bought one with less appearance, but with a better protection (which this was even cheaper).
Too bad - this article has a lot of potential in my eyes, only the implementation is flawed.
