hello!
I´m working about a Full-Scale Schlieren System and I want to take pictures about the schlieren effect!
For this, I have a FASTCAM SA3 brand PHOTRON (digital camera) and I have to select and buy a large format lens!
what´s the criterion for to select a Lens?
Let me explain the application!
1. The lens proyects the image on a Frosted glass or screen or photographic film (This is the image plane).
2. The FASTCAM takes pictures to this image plane.
I have two lens options:
a) APO SYMMAR 480mm/8.4 and b) APO DIGITAR 210 mm/f5.6, what´s the best option!
regards
