Using a Phase camera, has anyone had issues using lenses pointed straight down for a long time? Or more importantly, if so, does anyone have a solution?
We have stuck with Contax for a long time. But, the hassle factor is getting too big. One reason we have held off getting a Phase camera is that we heard that there was a focus change when the lens was shooting down from overhead for a long time. Then, our eqpt rental service said they thought it was now not an issue.
So we tried an XF with Schneider 80 mm lens. It sat all day high on a tripod pointed down at the set. And the focus would shift.
We really want to leave Contax behind. Does anyone have a sense of the scope of this problem or how to address it? Was this an issue with a prior series of lenses and we had just been given one to test with?
Thanks,
Gary
