uncorrectable distortion with kowa 8-ZHey Guys, Testing Kowa 8Z with 90mm Leica R prime on a Canon 5dm3 body. Noticing an uncorrectable (via stretching or disqueezing) warp to the frame. See image below, see how to the left of talent the window cabinet is slightly askew. See the door in the background off to the right of the frame is on a slight angle. See image below: Any ideas on the cause of this and what to do? All lines should be straight - images within frame on same plane and leveled.
Focusing- anamorphic first or prime? Proper alignment Q tooI 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? Thank you
