I think you'll be very happy with your Ike housing Jay.
Here's some advice from my past experience w/ the Ike S2pro housing that might help you on your trip.
With the extended dome port, wrap the barrel with something black, like electrical tape. That will help reduce flare.
When locking the ports into place, remember to grease the o-ring. That is Ike's advice and it's the only oring that needs greasing. After the port is locked on, you can check the oring seal by taking off the housing back and looking into the back of the front of the housing. Look for pinches in the oring.
Get some black paper and do this with your 14mm Sigma:
Otherwise, the front element sticks out a LOT and is prone to flare.
Good luck and have fun!
Cheers
