I already have a metz 58 AF1 P but, the Pentax fit, have just found out that a similar spec gun would end with the suffix O, for the Oly fit. I am getting rid of the K10 as, to be honest, it's too advanced for me. I have problems with remembering exposure equations, and it just freezes me. Consequently, I lose too many good shots. I ought to be some up here I guess.
Anyway, thanks for your help.
