I have Canon 5dm3. My prime is Leica 90mm. Using Kowa 8Z with redstan clamp.
1. When attaching the Kowa what is the proper way to align it to the prime? Should both the focus rings turn in the same direction? Do I align the infinity symbol of both the Kowa and Leica? If so, I noticed that when doing so the Kowa turns in opposite direction of Leica when focusing.
2. Since they both need to focus at "same time" when beginning initial focusing should I try to focus the prime first and then the Kowa or start with the Kowa?
