The good shell protects my 550D wonderful. I use mine exclusively for filming.
Shortcomings:
The silicone strap for the hot shoe adapter blocking my Rode VideoMic so that it can not vibrate freely.
But if required, I leave in such situations where a micro is used on the camera simply gone.
The change comes with a little practice without problems, if no lens is tuned.
Nett intentioned, but are required in practice is also the lens adjacent part:
It diminishes with my analog lenses operability of the diaphragm. But here it still goes well with exercise.
All in all:
Good protection for a reasonable price. Was already 4 Katscher spared and relieved repeatedly handling.
