Hi Chris, I changed my plan since I sold my LX-7, I don't have any camera for U/W now so no point going to Cayman although I'm highly interested at the Hollis Explorer. I'm waiting for the announcement of the Panasonic LX-8. If LX-8 has 5-axis stabilization with 1" sensor with 4K video, then Lx-8 would be my choice, otherwise GH4 it is. I will be going to West Palm this December to shop for apartment so plan to relocate to your neck of the wood next Summer, so you probably would see me around!
No worries. Though, we will have lots of demo gear down there, including GH4. Just saying'
Let me know when you move down here, we can go for a bridge dive.
