Mini domes & Tokina 10-17mm question

[Hetland]

I'm looking for feedback from folks using mini domes (4"-4.5") with the Tokina 10-17mm lens. I'm particularly interested in any negatives, and hearing from anyone using this set up in caves.

Thanks!!!

The negatives are that you shouldn't shoot wide open, best results are at f/8 and below. Splits are pretty poor and the dome doesn't fit other lenses. Other than that the small dome shoots fine.
