Bayonet or Threaded lens?

[OzeDiver]

In a couple of weeks I will be hopefully buying the ike sp-350 housing and probably then lens adaptor, there are two to choose from;

Optional adapters: #9306.80 allows attaching and removing the Inon UWL-105AD bayonet style lenses underwater. #9306.81 allows attaching and removing the 67mm threads of the UWL-100 conversion lenses from Epoque and Inon underwater.

I have done a little research and it seems that there are more filters and lenses that use 67mm threads but only some of the Inon lenses use the bayonet? So my guess is the threaded adaptor would be better? If anyone else has some wisdom about this it would be greatly appreciated.

The Inon PT-030 lens mount will let you attach all of the Inon lenses underwater that you mentioned in your post. Or you could go the Ikelite route instead.
