I've rented the Rokinon 8mm f/2.8 fisheye lens from Lens Rental, great lens, correction was great in Lightroom. This was done using my X-T1 at Two Medicine Lake in Glacier National Park at night.
Before correction
After correction
I did a bit of research after I posted, and it appears that the 50-230mm is 58mm at the far end, and the 55-200mm is a 62mm
I have a 58mm rubber lens hood that will have to work for now.
