I recently bought a couple housings on ebay to piece together a whole kit. So I have this massive 8in 5510.45 dome with the 4.25in extension tube. I also have a 5503 dome port. Ive booked a trip to Guadalupe Island next Oct and am hoping to get all of this dialed in prior to that. I shoot a Nikon D300 and I imagine my 10-24mm 3.5-4.5 will be the lens that I use. Only other one really would be the kit 18-70mm. So Im just trying to get an idea of whether or not I really need 2 dome ports and maybe what the advantages/disadvantages would be. Is the large one the more verstatile other than it being the size of a Frisbee?
Any guidance would be great.
Thank you much
