I wonder if anyone could help me or provide me with any tips on focus pulling when using a Wide Angle Inclining Prism and sharping at high speeds such as 300fps and above?
When I used a Prism once before, I noticed there was a slight difference between what I measured to the subject, and then by getting eye-sharps? Is this because the Prism is acting as a mirror?
Also, when filming at high speeds such as on the PhantomFlex 4K oe even Red Epic is it a matter of luck and hit-and-miss as to whether you get the timing right to anticipate the action? For me, it is as if you have to second-guess the action or time the pull depending on what speed you are at.
Any help would be appreciated. Thanks.
