Anyone use AUTO ISO

i use auto ISO most of the time. But in lowlight, no flash condition, i usually set the ISO manually and crank all the way to 12800.. Noisy shot is better than blurry shot!

I know when and where and why to use ISO. Obviously you want to use as low of ISO as possible for sharper images, but cant always do that because of lighting.

Im wondering if anyone ever uses auto ISO? how good is it? im thinking might be nice feature to save time and easier. But curious how good it is and will it always choose lowest possible?

I do once in a while at M if I'm too lazy. Or if I shot at AV mode between shadow and bright side.

Never used auto iso before. I trust my own decision to use whatever iso is needed.

Auto ISO blows chunks on the 40D. I never used it.

I have no idea if it's any better on my 1d3, I still don't use it.

I'm in Av 90% of the time and I don't want the camera messing with my shutter speed/ISO combination. If I want faster shutters, I'll raise the ISO. It's certainly easy enough.

But then, this is all based on how crappy it was on the 40D and now I don't care.

I used it occasionally on my 5d2, but often I wasn't happy with it. In lower light, and AV mode, it tried to the 1/FL shutter speed, but often that is too slow. So, when using a 28mm in low light, it would keep the shutter speed at 1/30th, usually too slow to take pictures of people. Even with a 50mm or 85mm lens, the shutter speed often was too slow if someone moves at all.

I used it sometimes on my 1dsiii. It isn't called "auto iso", but works the same. You just set up the safety shift to change the iso, and then use Tv mode and set the shutter speed at what ever you want. But I still haven't had a camera with really good, programmable, auto iso in Av and M modes.

Hmm... no, don't think I've ever enter "A" zone in ISO. I guess it's 2nd nature to operate in the (exposure) triangle. Can't say I fully trust the camera to see what I want it to see.

I find that auto-ISO works well when I'm taking action shots....such as soccer....and it is partly cloudy....tough to have a constant ISO when the light conditions keep changing.

Other than that, it's manual ISO all of the time for me.

Exactly what I do in exactly the same conditions. Rather than miss a shot while twisting knobs, I'll let the camera do it. But always prefer to us M and dial my own ISO in when possible.

Whats Auto Iso?

Where can I find this?

I have some auto-iso's for sale. I'll give you a good deal!

Never... I've got nothing against using it, I just don't.

I use it in Manual on my 7D. I wish i could set exposure compensation and that auto iso would go to 6400. Why can't we have these things?

I'm with you and all the other posters on wishing I could set EC (although I've been trying to figure out how Canon would implement it - another mode, called TvAv, and/or another button so you can switch the top dial between shutter speed and aperture, and leave the rear dial for EC?), but other than that, I love auto-ISO - get to pick both your DOF and how much you want to stop action, and the camera does the rest. I like being able to set both of those things at the start and not have to touch it again for the rest of the day/night. I just change EC in post nowadays if it's not too far off.

My 60D had a menu option to let me change my auto-ISO range, and I was able to pick 6400 as my upper limit (which I needed since I shoot a lot in low light) - does the 7D not have this option?

Tops out at ISO 3200 and no option to adjust. And add another vote for EC with auto ISO.

I don't use it and I can't see the point.. Learn to choose your ISO to suit the lighting conditions..

I started experimenting with it last year. I actually like it a lot for sports, wildlife and situations where light is changing. I always set it +1/3 and i must admit, its pretty accurate. Its the bomb for sport shots in TV mode and fun to play with to get different affects. Didnt realize how much affect 500-800 has in the water, so iso is one less thing to worry about.

Some modes automatically select auto iso on the 40D and as much as I love manual mode I am becoming more attached to these modes which use the auto ISO as I have more success in keepers with them. There are times I get frustrated that I cant use a higher shutter speed and have to go manual, but more and more I have grown to like auto ISO.
