Hi
I'm not planning on changing my entire system, just the back.
So the question is just which back I am to go for.
I'm currently looking into the prices of a used/refurbished p25, or a ref. Hbl cf back.
It's not a straight wide angle I'm looking for, it's a as-near-as-possible full 180 degree angle Fisheye, ergo, a back that will work with the Hbl 30mm.
