When I turned my camera on today, the "!" was on in my VF. If I deselected the "shutter" in the "!" menu it turned off. Or...if I activated the shutter! That's right, it is working backwards for the shutter. I powered down, re-read the all, user and scene files, turned off and on the "!" menu items but it seems to like to tell me when the shutter is off, not on.

Any ideas how can I fix this?

Is this in a 350 or a 700?

This occurs in the 700 when you switch to progressive.

Essentially think of it in terms of: if the warning light is on my shutter is set to something other than 1/50th (25p/50i) or (i assume) 1/60th for 30p/60i.

Assuming 25p, the logic is that if shutter is off in progressive you are actually at 1/25th of a second shutter so you are warned. So you have to turn it on and select 1/50th to make the warning go away.

In interlaced when shutter is off it is already at 1/50th so no warning light.

Same I'm sure would probably apply for 30p / 60i land but with 1/30th 1/60th fractions - though I've not shot in these yet.

I have a 700 and thanks, Peter! You nailed it. The camera was set to 30P and I had the 1/60 shutter on. Perhaps the warning "!" is to remind us to turn the shutter on when shooting progressive.

yea - that's exactly the logic of the warning light. The motion blur in progressive with shutter off is substantial and for day to day shooting it's important that the shutter is turned on to clean this up.
