dykvideo 5 Posted March 15, 2017 (edited) Hi. Just changed my Seaandsea canon 7d housing to a Seaandsea canon 5d mklll housing and have a question regarding the dimension. I have a bulkhead for an external monitor and wondered if the diameter is the same in the two housings. I believe the dimension is 16 mm?? Thanks in advance.
