Auto ISO...

[mav496]

Have just received my new 5DMkii and have only taken a few shots with it, but in love with it already! (Will post some shots up soon!)

One of my questions is.... Whilst hoping to do some more weddings in the near future, do any of you use the 5D's "Auto ISO" setting, or do you manually select the ISO depending on the shots?

Still getting to grips with advancing to such a great camera, so any help would be appreciated, as always!

I don't use Auto ISO. Just used to shooting without it.

I manually select the ISO depending on where I am and how much light is around.
I also always shoot in manual mode.

Practice and have fun

5DII is awesome! Just shoot a ton with it and you'll be there in no time

Never shot with auto ISO.. What the heck does that do

I tried auto iso on my camera, but I found just like any auto mode the exposure between shots varied a lot and meant I needed to process each image. Shooting full manual means you can batch process which is much faster.

you should manually adjust iso for the situation at hand. The shutter speed you need and the shutter speed auto-iso will give you will rarely match. Many times you will need a faster shutter, resulting in higher iso.

When I first started, I needed auto ISO. Now, I can't find the disable feature quick enough!

I remember hating the 5D because it didn't have auto ISO. Oh how things have changed.

Auto ISO - the best thing ever! ->for the parts I dont use flash. It get turned off when using flash as it selects the lowest available - i manually select double when using flash so the flash and batteries only have to kick out half as much. But for speeches / ceremony where I tend not to use flash its ideal. And you dont hear my constantly fiddling to selct iso. It automatic - its fantastic. Quite shocked to hear most are against it.

Didn't even know my 5dIIs had that function.
About the only thing I leave up to my camera is metering and shutter speed (sometimes outside).
When I'm inside (reception, etc.) I set the ISO, shutter and F stop. Use the shutter speed to adjust for changing ambient unless it get below hand holdable comfort, then up ISO a stop.

With 5DII high ISO noise performance I am comfortable with anything up to 6400.

If your comfortable with anything upto 6400 - so am i - then thats pretty much everything so why waste time selecting. Also, shutter speeds - you should be able to select the slowest shutter speed allowed when using auto ISO. Mine is set to an 80th of a second. I say you should be able to do that as I use Nikon (indeed) and thats what i do with mine. (i know its a canon forum but the chat is good here). When using flash in auto itwill select iso 200 - i will turn auto iso off and select higher like 800 (still no noise) so the flash and batteries only have to do a quarter of the job. Have a good play about with it - shoot outdoors then indoors and not have to worry about forgetting to up your iso. Its not right for all eventualities but for the ones it is it works great.

Only time I've used Auto ISO on my 5D MkII was at my 45th High School Reunion. Light was adequate but varied according to where you were in the room. Since I was shooting for my personal use and didn't want to worry about camera settings, I tried the Auto ISO setting and was very pleasantly surprised by the results. I'm looking forward to using it more in the future.

Al Rohner - nice one!

Have to agree here. I didnt know about it either until a very respected sports photographer told me about it and specifically how he uses it in his work flow. Im blown away with how it works in TV mode and im applying the techniques to our wedding photography work. IT WORKS.

Look , we all know what shutter speed we need to freeze action 99% of the time. We know that we dont want to handhold below 1/60 and we know flash is going to freeze motion so anything over 1/320 will likely not have motion blur. Auto iso takes a lot of problems out of the equation. In TV mode, you set the shutter speed at 1/320 (just an example),, the camera is going to set aperature. Auto iso allows the camera, who is a hell of a lot smarter than i am, to get the correct settings and coordinate with that flash, especially with ETTL flash operations.

I think you guys should give it a try and be as pleasently surprised as some others are finding out. Its a great tool to use once you understand what it can do for you. I frequestly set up our 2nds camera this way with the 135L attached during a ceremony. I know i need a shutter speed of 1/160 to get good results with the 135L. TV mode at 1/160, auto iso during a ceremony with no flash gets us great results especially if we have changing lighting, which is very common in churches and outdoor vents. Even better results when we can attach a flash. Its a good tool to use.

Get Syl Arenas' book-- speedlighters handbook. It will open your eyes. I was a 100% manual shooter who has completely changed my thoughts about the way we will cover events since reading this book.

Auto iso is a good thing but not a 100% problem solver. It is a great tool. I love it. If you have a camera that does this, you should learn how to use it.
