Is 60 mm port too long?
I've been using it with my Subal housing and the flat port I use for my Canon 60 macro lens. There is no vignetting and the port is only just long enough at minimum focus distance (the front of the lens is VERY close to the glass port). I don't see this as a problem as I will never be focussing that close with this lens because the minimum focus distance is only a few millimetres in front of the glass port and it is almost impossible to light the subject when it's that close. There's some information and shots from my first dives with the lens here:
