ISO Setting

[mbworldz]

Does anyone use the "A" auto ISO on your 5D Mark III and 1DX ? Just trying to see what other pro is using.

Rarely.

 

[Loswr]

Often. With limits.

I use auto a decent amount, and set the limit on a regular basis, but never with flash work, as it "auto" sets to 400. But I also only run a 60D

 

[Harry Muff]

All the time. Tv set to the minimum and the aperture can do what it wants indoors.


Outdoors in good light, Av with Auto ISO.




I'd rather have a some noise to clean up than miss the shot altogether.

The camera is a pro body that is set to auto ISO but I am not a pro photog
That is when I am shooting in M mode and the light is going to vary quickly due to changing angle of the shot and I would not have time to fix the ISO...

 

[privatebydesign]

Never.

Bit I can understand why others use it.

Same here.

Here too.

Occasionally, when lighting conditions are rapidly changing and I don't want to fool with it.

The 5diii has spoiled me. I use auto ios most of the time and don't get too concerned because the noise is so low.

 

[Grumbaki]

Never.

I use it rarely ... when it is used, it is when the lighting conditions are unpredictable ... to give you an example: while I'm doing bird photography where there are lots of trees/thickets I use Auto ISO, bcoz if the bird I'm shooting, in well lit with direct sunlight, suddenly goes to perch on a thicket or a branch where it isn't getting enough light to capture the image, I may not have the time to change ISO manually.

 

[Vossie]

I use it rarely. Changing iso manually can be done very quickly without even taking your eye from the viewfinder.

Yup, me too. Not all the time, but often.

 

[adhocphotographer]

I generally use it unless i specifically want low noise or am shooting portraits with flash etc...

Personal preference...

Now that I use a 5DMIII it is the first time I use autoISO almost all the time, outdoors my usual setting is Av with autoISO and often 1/3 or 2/3 of positive exposure compensation. In manual mode there is no way to adjust exposure, so I avoid it if I can.

I find the auto ISO performance of the 1DX to be amongst its most usable features. When I do wildlife, birds and macro shots, I want to have full control over both shutter speed and aperture and therefore primarily use manual mode. Avaliable lighting can shift dramatically and by using any of the program modes (P, Av, Tv), you only control either shutter speed or aperture and not both. With fast moving objects and long lenses, you first need to find whatever you are shooting in the viewer, than try to frame it, then get the focusing right and on top of this adjust ISO settings by controlling shutter and aperture. Puuhhh :-X

On earlier bodies (1DsIII, 5DII etc.) I actually never used it, to secure the lowest possible ISO settings. But many shots were ruined by slow shutter speed (Av mode) or too deep or too shallow DOF (Tv mode). With the high ISO performance on the 1DX, that is much less of a worry and I rather accept occational grainyness, with proper DOF and shutter speed, than the alternative.

I'll readily use it if I'm shooting Av/Tv and in variable light conditions. I would use it all the time if they added an exposure compensation function so I could shoot in manual.

For those that use it, is your ISO set to 1/3 or full stops?
