uncorrectable distortion with kowa 8-Z


Recommended Posts

Hey 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.

The Kowa 8Z/16H is distorted near the far left and right of its image coverage. at 90mm on a 5D, you're pushing the boundaries. That is some of the distortion. First, level your tripod, then do what others are suggesting with a flashlight for alignment. Your clamp can make a big difference too. Get a good one that is sized to fit snug. The anamorphic shouldn't be held in place by the screws. They should mainly just be used for tightening to prevent rotation/misalignment.
