Ahh, sorry i guess 120 not 160 degrees. That is for the exposure? (i´m not sure and lost my books...i think 120 d/ 360 d x 1 / 25f/s = 1/75 sec ) 180° is at 25f/s = 1/50 ; 120° is at 25f/s = 1/75 ? So 120° at 24f/s is 1/72 ?
Hmm, the Number will be #2312. It´s this model 1 or 2 from ebay, they´ve wroten about it in this thread!
Thanks!
best, Philip
