Anyone know why this is? Or how to work around it? I can't imagine why auto ISO wouldn't function. At this point it would seem for wedding work the best thing to do is to set a high ISO, then run the camera in Aperture priority, causing the camera to slow down the shutter speed as needed. This would allow a completely auto setting for the camera, but with the disadvantage of having an uncecessarily ISO, but at least you could run continously without having to shut down and change the ISO every time lighting conditions change.

Do you physically have to turn off the camera to change ISO, or do you simply have to stop recording (but not turn off the camera)?

I have to stop recording to change ISO, that is normal. But I do not wish to stop recording during a live event.

Problem is that Auto ISO is disabled when using an FD or EF adapter, that is the only issue at this point.

Jeff,
Did you get your auto Iso issue resolved? I tried the auto iso for a bit to test it and it seemed to change alot and I would be a little nervous to use it for a paying event. How is it working out for you? Do you notice the changing iso during recording much?

Thnks

I use an variable ND filter. Then I pump up the ISO and adjust it as needed with the ND filter. It's a work around, but it works.

Steve I used it on two out of four cameras a couple days ago, worked great. During the priest's homily it was changing noticeably as the priest moved, so I stopped recording and set the ISO to a fixed value, but otherwise I never noticed the ISO changing at all during about 6 hours of filming.

William H has also mentioned using auto ISO with good results.
