I'm selling my Inon bayonet lenses that don't fit my new camera. I also have the Ikelite adapter that fit my old F810 housing and the double lens caddy that fits on ULCS arms. I believe the serial number of the adapter is 9306.80. The lenses I have are:
Inon UWL 105AD - $250 2 x Inon UCL 165AD - $130 each Double lense caddy (ino.456212143185) - $25
I will let the whole set go for $500. I used the lenses many times but took good care of them and they are in good shape.
