I am a bit confused as to if I need a 'step-up' or 'step-down' ring (or something else...)
I have a lens with a 58mm thread (sigma 105 macro) and I want to attach a cokin p filter ring with a thread of 77mm.
I am not using the 77mm ring for it's normal use. I have glued a 'close up filter' on the top of the 77mm coking ring (and not a proper 'close up filter' but something I have scavenged from the front element of a broken jupiter 36b lens)
Anyhow, here is an image of what I want to attach...

Is it possible with a step-up/step-down ring or something else?
