Mike good evening Dan Stanley here, I purchased my housing and ports from Dennis at your shop. I am purching as I get the monies. I didn't know about this video untill tonight. I had already muddled through setting up my housing and wish I had know about the video, it would have made the set up way less stressful. I emiled Dennis tonight asking about the Fx ext. ring you used on the video to attach the fisheye dome port. I purchased the DX macro port base, and the DX macro port 50 to use with my 60mm, and to possibly use with a 105mm in the future. Here is the question Do I have to have the FX EXT. ring to use the dome port. When I was setting this outfit up with Dennis we never discussed having to use the FX EXT ring with the dome port. I leave for Little Cayman in two weeks and need to figure out what all I need. I purchased to sets of the Sea and Sea sea arm VII 's. I have my TTl Converter III. and I am borrowiing a YS-110a strobe to use since I haven't been able to afford them. Looking at the sea arm VII's am I going to need another clamp to attach the strobe to the arms? Dennis usually gets back with me within a couple of days, hopefully you can clear things up for me. Please get back to me asap. Thanks Dan P.S. Mike Dennis contacted me today 7-25. He is sending the ext. ring Monday. He has been very helpful in the whole process of setting up my outfit. Looking forward to doing business in the future. Thanks for everything. Dan
