The bayonet fits perfectly and is designed in a way which does not require supports. Great!
Although the bayonet does not have any
bump to act as a locking mechanism, the material friction is enough to prevent accidental opening.
Lens have some extra space around them and are held in the middle by the foam, ie. not touching the sides.
Another safety level when travelling with photo equip.
