Conclusion:
- The plate and the adapter are made of cast aluminum - and the locking lever - wrote unlike the previous Reszendent.
- When replacing one should note the engagement of the alignment piece, because the secure position of the camera is only guaranteed, and damage to the locking mechanism (cast aluminum is soft!) The violent attempt to close it despite incorrect positioning should be avoided.
- For this price for a pair you can get over this small lack - at least I'll get myself at least a second pair.
