Well, is actually a good idea - 2 points moving me to return! The silicone body fit relatively exactly on top of my D5100, up to this non-silicone strip below the display. Because I really wanted to give up my bag for this envelope, I tried the part, a hour for "walkies-go" with my dog out. This very loose silicone strips caught (worn camera neck strap) several times on my Jack button.
The other point is the really extreme slipperiness of silicone case - I never thought! The body is a little fuller, more comfortable - but also smooth as a fish!
I can not say anything about the screen protector, did not plan it.
In summary, I was actually torn - send the envelope back but since I when touching the camera really almost "focus" had to in order to handle solid.
