Since AOI has released a PEN to OMD adapter for their mirrorless housing I was looking at going to a larger dome port. I currently have the Olympus E-PL10, in the AOI UH-EPL10 housing. I want to get with an Olympus 7-14 f/2.8 PRO, or a 12-40 f/2.8 PRO lens to use with the system. AOI makes an 8" Acrylic Dome Port that will work with both lens, on the PEN housing, using the adapter. My concern is traveling with an 8" dome. How difficult is it to travel with a dome port of that size. I typically put my current set up in a back pack to avoid the Pelican case. Can the port be safely packed in my regular checked bag? Is it worth getting an 8" dome with the E-PL10 or should I stick with my 4" dome? Thoughts would be appreciated.
