The dispatch from Hong Kong was fast (8 working days), the packaging lousy: a plastic envelope without any padding.
The panel consists of two parts: a which is screwed into the lens and then to function as "bayonet base" for the second -the Blende-. Would he even if he had been, not deformed during transport, as shipped assembled. Went to the happiness to be addressed.
The part for screwing has an indicated thread which (not screw) was more or less viable is, but after several attempts to fix the lens. The panel could be put on like a bayonet, would they not been taken when transporting affected. Function in long-term operation questionable ... fortunately was so cheap that it is not too painful.
I-not-again.
