5DMKII auto iso is a joke

Hey, even the 1D's have Av and Tv, so they must be useful...

AV and Tv are very useful, I use them when im shooting things that say..move

Manual when it doesnt or i know what i need, Av for most everything else

See for me the good implementation of Auto ISO would be to say "Look, I want you to keep the ISO as low as possible, but i want my shutter speed at least 1/500, and i want my aperture at f/8" Even better if you could program it lens specific, ie i want that with my 100-400, but with my 10-20 you can let it go down to 1/20 or 1/30....

For me that would be a blessing, I've had a few shots wherein i've gone from shooting a bird in a tree at ISO800 to a plane against the sky....usualy because the oppertunity is there and i cant adjust ISO without risking missing the oppertunity...

i think the op wants the flexibility of having a smarter iso that is adjustable, much like the upgrade from full auto to custom auto; why not have a full auto iso and a custom adjusted iso preference?

again, software/firmware issue. the way i see it is this: pro cameras are starting to seep into the prosumer market in which parents who want to take quality pictures demand the best camera within their budget. here's where the 5d mark II comes in. that's why you see a bunch of kid photos weekend warriors. etc etc.

professionals separate themselves from prosumers by their ability to create and transform images that make you stop and think.

There is nothing wrong with the OP wanting more flexibility with there camera in whatever sense they want.

However that was not the original issue here

Here complaint here is the AUTO ISO Drops the Shutter too slow to use

Instead of complaining and wanting the ability to boost the ISO 1/10th which is not the issue here, there should be the ability to use AUTO ISO complelty in Manual where we can set the shutter speed we want and Aperture and then have the camera set the ISO..

Most people complain here about the ability to change the ISO when needed, however 9 out of 10 times when shooting i can have the aperture and shutter set where i want it, however some times my subject will change or a cloud may jump over head and i am now required to boost the ISO that extra 200 or whatever, So the ability to have MANUAL control over the aperture and shutter and complete AUTO ability with the ISO instead of the locked in 400 crap would be IDEAL.


Also keep in mind that her complaint was a intermitted issue.. I could see if every shot was screwy but it sounds like software may need to be tweaked in certain scenarios as she does not have it happen all that often. Saying that you are having an Intermitted issue with the AUTO ISO would leave me to think that every other time its spot on and working to your liking.

this is the best suggestion yet...for on the fly photos its just to nerve racking to have to figure out shutter, aperture and ISO within a matter of a split second

and as another member said i too also comapre what the camera would set an image at in any of the auto modes, and compare it to how i would set it

I shoot manual when I'm in a studio setting with moonlights, light meters, etc. When I'm out shooting in natural light I *rarely* shoot manual, why would I? I shoot Av and Tv modes when I'm shooting natural light depending on what I'm shooting. I also switch between single shot mode and servo.

With that being said, I've never used auto ISO... I haven't even experimented with it. I see absolutely no benefit to using it. It's all to easy to find a good ISO setting for your location and make minor adjustments with your shutter or aperture. If I do need to make an ISO adjustment, I quickly hit the button, roll the wheel and continue shooting in a fraction of a second without the camera ever leaving my face. It's fast and easy.

I don't have noobs wanting to shoot with my gear, not that I would let them anyway. If they want to take a picture, I have a P&S in my bag they can play with.

I honestly don't know why Canon puts all those amateur features on their pro bodies. I would agree if it's there it should work properly. If not, just get rid of it, most of us wouldn't miss it.

I never use it, but they should just take the feature out completely at this rate, like the print button on most cameras =P They could probably replace them with much more functional features.

Anyone purchasing the 5D2 for the Auto iso will sadly be a very regretfull decision. The 5D drops your shutter speed so slow that even the steadiest of hands guarantees a motion blur.

And for people saying they are always on manual and pick there exact iso.....

Sometimes you just want to hand the camera to a novice or shoot without a care and a simple cf function to pick a higher iso rather than slower shutter speed would be a no-brainer to add on the next firmeware update... CANON.

blah blah...mumbles best camera ever other than auto iso... mumble mumble

Well, your point is somewhat accurate, as there could have been better implementation of autoiso.
That much said, If you are giving your camera to a novice to take pictures of you, put it on the green box. Depending on what you are shooting, autoiso is still usable. Forexample, I have a custom setting (c2) set to TV, auto iso, shutter speed of 1/125 second, to take picutures of my kid indoors. It ends up generally shooting my lens wide open, or stop down 1/3 to 1 stop, and chooses the lowest possible ISO.
Another way around it if you have firmware 1.07, is set the camera in manual mode and live view, with liveview set to movie and image. then you can set your shutter speed and aperture, and the camera will set the iso. Its perfect for strangers, b/c most stranges are used to shooting via live view. You just gotta tell them to press the focus botton before shooting.

Again, the implementation of autoiso is not as good as it could be. I doubt there is anyone out there that is purchasing this camera specifically to use the autoiso feature. As for those saying its a non pro feature, I am sure its a nice feature for a pro wedding photographer to have.

Use Auto-ISO in conjunction with TV mode. That way you can set your shutter speed, and have the camera figure out the rest.

Whats wrong with that?

Hell, I'd love my 350D just to HAVE an Auto ISO mode.

I had to give my camera to my Uncle to let him shoot a ceremony with me involved, and because we were traveling between several places I wanted to keep it in RAW (I don't trust the AWB after some back incidents...).

I had him keep it on Av set at f/2.8, and because one of the places was dark I had him keep it at 1600 so we could get shutter speeds around 1/30. Of course, outside the shutter stayed around 1/2000.

Can't you set it in manual, set at 1/Focal Length with the widest aperture, and then set Auto ISO and be done?

Greetings,
I have never tried the Auto ISO on my 5DII till you mention its problem. However, I see no such problem on my as you describe. Apart on M mode, ISO can go up to 3200 (max). I think thats a very high ISO to give you a quality large print. Maybe time to invest on large aperture lenses if you still find such high ISO wanting. Enjoy...

Greetings,
To add on what I have just said, I tried it again with 24-105L and 70-200L. The ISO and shutter speed do change when zooming in and out (P mode). ISO drops when zooming out and shutter speed reduces to hand holder speed. i.e. 1/25s @ 24mm and 1/100s @ 105mm; 1/80s @ 70mm and 1/200s @ 200mm. The camera is programed to use the lowest ISO as possible. Enjoy...

Am I the only one that picks the iso before I start shooting?

Never used auto iso. I like making decisions myself. Changing iso is a very quick operation for me. No problems there.

There's a time and place for the different modes.

I for one have not used auto ISO as I usually shoot in manual and the ISO always defaults to 400 - not usually what I'm aiming for. However this is a great tip which I have implemented for times when you need to take fast candids, thanks Kevindar.

Well I thought the auto iso on my 40D worked fine, I thought it worked better on the 50D and I thought it was great on the 5DII when I tried it.

Honestly though, I dont use auto iso and find it very quick and easy to change for the correct iso, the buttons on the camera are easy to remember for blind quick changes, my 1DIII is even nicer with its layout.
