I hadn't given that a thought, the end protection cap for the lens has vivitar on it and Optimax on the inside of the lens, so perhaps it could be just a Vivitar cap. Thanks for pointing that out.

Hi Linda, you confuse me slightly you mention Viv. then Optomax, definitely different manufacturers.
All the advice you have been given by others is pretty much correct, it's worth a tenner, however, you don't state what cameras you have, it may be worth keeping and experimenting/having fun with it.
