I am interested in installing a new lens on my CGO3+, once the warranty runs out. I was a little leery of doing it myself when I heard that some of the CGO3+ cameras don't utilize threads anymore and are just glued in. I visited www.peauproductions.com and noticed that they carry a threaded mount that you can replace in the CGO3+ if yours does not have threads. I guess my questions is, how hard and time consuming is it to refocus an aftermarket lens? I am interested in either the 3.97 or the 8.25, but is there the possibility of using both? Would there be an issue with swapping lenses depending on the FOV you are trying to achieve? If it doesn't take to long to refocus, I might pick up both lenses for versatility's sake. It would be great to hear some feedback from someone that has modified their camera with a Peau aftermarket lens.
