yawn... shot several paid shoots so far with the 5d3, a few using auto iso.... no problems so far... got my min shutter set to 125 when using my 24-105, and auto iso does the rest. but just think of it, seriously, 10 years ago there was no auto iso, you had to dial it in, use an external meter because in camera meters, if any, were crap, and even with that, you would buy a brick of film, waste the first roll of the brick testing it so you can dial in exactly how it will expose with your meter, and compensate from there... gasp... whatever did we do? Going between indoor and outdoor scenes... you had to gasp, use more light, waste the rest of the roll to change film, or if you were the bomb, you kept notes on how far you were so when you went back to a roll you can auto advance by manually shooting blanks to get back to where you were without wasting rolls. Dont get me wrong, I appreciate auto ISO, but i'm not going to blame it if i miss an exposure, afterall it is picking up after my lazy butt because i chose not to crunch the math and do it myself. Also about the black dots, i offered a workaround for low light situations and black dots on the other thread but no one bothered to check it out. Bright sunlight doesn't show the red confirmation, but if you cant see the dots in bright light, you need your eyes checked.
