ISO - A Flashing

[Lawrence]

Ok I know (or at least I think I do) that this flashes when the ISO I have selected will be over-ridden because of low light issues.

My question is do I want this on all the time?

Its a bit irritating.

Should I leave it as a warning and adjust my selected ISO until it stops flashing or do I leave it on to override my selection?

You are asking about auto iso, right? (not just the indicator. I don't think you can disable the just indicator, you must turn the whole function off.) Sorry, still sipping morning coffee,lol. I only use auto iso for certain things. Otherwise I want to know exactly what iso I use at all times. The auto iso situations, with acceptable limits programed into auto iso.... 1. shooting low light hand held. Shutter priority with shutter set at the minimum required to do the job. Not necessarily very low light, it could be a sports situation too where you must have a minimum shutter speed or the shots are worthless. situation 2.... For a specific need, I require a certain shutter speed AND aperture, so camera in manual, S & A set to my needs, camera on auto iso and hopefully auto iso can raise/lower to get the exposure right. Other than that, I keep iso on manual and try to stay aware of what I have set and decide per shot what is best if I don't have enough light.

If you're talking about the flashing AUTO ISO indicator in the viewfinder then there's no way to turn it off without turning off auto-ISO completely as nickt said.

I've actually learned to love Auto ISO in situations like the PhotoWalk I was on 2 weekends ago. In an outdoor situation where I'm constantly changing lenses I simply set the ISO to 100 in Aperture mode, turn Auto ISO on with a minimum shutter speed of 1/125 (since I have my 70-200mm with me, otherwise it goes to 1/60) and a max ISO of 3200 and off I go. The noise performance is so good on the D600 that until it hits 800 I'm not even thinking about it, and even then I'm able to reduce or eliminate it in 95% of the cases where it's noticeable using Nik Dfine 2.0 without impacting sharpness. This way if I wander into the shade I'm not vexed by underexposure. And the flashing indicator reminds me in case I am, and it's a simple press of a button and turn of the wheel to turn it off. Flashing is good. If you don't want it then you shouldn't be using the feature.

Thanks Nickt and BDH. I thought more or less what you guys have said but Iu think I was worried in case it was saying "Alert - something wrong" whereas in fact the message is "I may have to change your ISO for these settings but feel free to pull the trigger - all will be fine"
