Hello
B
Boggyharpa , personally I would recommend to go with raynox as I heard good opinions and you can get good details as well. I think more help will be able to tell
Helix_2648 ,
MinitecaPhotographie or
rcorteschile , as if I’m wrong they had experience with raynox attachment.
By the way, as far as I know raynox are just a small attachment to your lens , and doesn’t consider as a lens. You might look for a proper lens for Olympus , maybe
nataliaflejszar&Photo or
Ron Westbroek can give you a better advice , as I'm a canon user.
