what's the difference between the 2?
and does the $250 for the 77mm expodisc justify the price?
wont it be 'troublesome' to take a reading everytime before you fire?
cos diff lightings(shade and sun) i have to retake the scene?
and if it's useful, how come i did a search, already found a few people selling/sold it?
please share.
