The lens is has a M12 thread on it and the SV305 Camera is set up for a C/CS Mount lens. I had to get an adapter to convert the C/CS Mount on the SV305 to accept the M12 on the lens.
I ordered this adapter on Amazon but it came direct from China so it took a bit of time to get here. It arrived while I was on vacation last week.
Aside from the orientation being different (north is up on the older lens and north is to the left with the newer) there is a much wider view of the sky in the new lens. The orientation difference is just because of how I angled the camera to try to get the most sky view. I may reposition where I have the All Sky Camera to try to get less of the surrounding houses and such.
