Don't know if this is the write foum for this, but I am shooting some stop-motion, on video. And i am having trouble properly focusing the lens'. I seem to be getting some vinyeting on the very edges of the frame.
THe camera's are JVC KY-F1030's and they are mounted with Fujinon Lens' (a threaded mount).
Anyways, the cameras have a back focus, and so do the lens'. I can properly focus using an Accu-chart. and once i do that I can zoom in and out, and not loose focus. But as soon as I go wide (7.5mm to 14mm), I totally use focus on the edge of my frame. I am shooting at 5.6 to 8 so I would think that should give ample enough depth of field.
anyways.. I am just wondering if anyone has any sugestions or tips for me to try and fix this, or to prove that these lens' are in fact crap...
thanks in advance
