In film days, losing a stop meant shooting 200 instead of 100 ISO film or 
400 instead of 200.  The noticable grain jumped up significantly each 
increase and different films also rendered colours slightly differently. 
Bbeing low noise and low vibration meant the RT was perfect for indoor 
concerts/recitals etc. where you are not trying to be obtrusive. The 'no 
blackout' meant it was good for following action in s****t. Except these 
situations also require you to get the most out of your film sensitivity
and 
1 stop was critical. The fact that there is little discernible difference 
between ISO100,200 and even 400 on the latest Canon sensors shows that
this 
isn't really a limitation anymore. Granted it would be a backwards step in

sensor sensitivity but they way sensor development has been going, it
would 
only be tem****ary one.
