I've got both of the above on loan for review. Fab. I won't go into a load of detail because I want to think it all through in depth and shoot a lot more, this gear is non-trivial (an understatement!) and getting the best from it will take some time. So I'll just share a test shot from today, in which I was shooting a bracketed series to see how much alteration to the 'regular' lens focus scale distance needs to be made in order to get focus right when shooting with an IR pass filter. I am using the Lee 87, which cuts everything below 730 nm.
