Not so easy- the Pentax AF140c ring flash accepts a maximum filter size of 58mm; any size above this will mean the ring flash just cannot be attached to the lens. I understand the filter size of the 200/4 macro is around 72mm RK [EMAIL PROTECTED] wrote If it has a filter thread you should be able to attach a ring flash to it.
