Doug why didnt you design the prism adjustment akin to how it is done in the FW8G? To have to remove the entire camera assembly to adjust the prism, and then repeat until it is in the right position is a right pain. I have to say this is rather a poor design. Also, I attached the SC3 to my STX FW7 today and 3 of the screws did up tight, the 4th stripped the threads on the FW and now freely turns. Martin
