100 hundred or auto in normal light

Depends on your camera. For street I shoot at iso 800+ to get a decent shutter speed and DOF, even in bright sunshine. 100 is too slow for street.
will have 60d 60mm macro as main camera may take pl3 as back up

It would depend on what you mean by 'normal' conditions; there are so many variables, your choice of ISO can be dependent upon many things.
I don't shoot 'street' in the way that you do but I do sometimes shoot people and vehicles, most of which are moving and I'd agree that 100 is too low to allow a usable shutter speed.
To answer your question; I don't think you'll see an appreciable difference in IQ between using 100 and 400 using a modern camera.
I'd avoid using auto ISO though. You never know what you're going to end up with.

I shoot a lot of my street stuff at 400 ISO, and I find the results are better not worse.

It really depends on your camera.

With my Nikon D800 (and the D3s that preceded it), I routinely used ISO 1600 for street photography for the reasons cited by SteveCharles above. On the old D300 I used ISO 400 as the high ISO performance wasn't quite as good with that camera.

Basically, for street (including performers in the Royal Mile next week), I will hope to be able to use an aperture of f/11 and a shutter speed of at least 1/500. I'll use Aperture Priority set to f/11 and the ISO set to 1600 and hope that it gives me a fast enough shutter speed. If not, I will open aperture to f/8 and, if that still doesn't do it, increase ISO to 3200 or even 6400.

Its hardly going to depend on your camera is it, it would have to be very very old to have any effect Smile

With EOS 60D ISO100 RAW for landscapes or cityscapes and ISO400 JPG for people and traffic in the streets. Image quality will be acceptable with ISO400 - as image quality is conditional on the photography subject as well. Rarely said, but important. Blur from ISO100 would be nothing better than blur from noise reduction with ISO 400.

Hello Ian
I'll be going to the festival fringe. Depending how bright the day is I'd set the Iso to 100 if overcast 400
The lens I will be using is 24-105 which I see you have one of this range, it gives me the extra Flexibility . Because of the crowds I feel the macro would limit me to a certain type of shot, you could easily pop the macro in your pocket.
Hope you have a good time

Yes, noise is present at any ISO in any camera, and in modern high-Mp cameras it can be noticed in shadows even at ISO100 - unless some degree of noise reduction was applied. Here I meant motion blur at ISO100 though.

I do a lot of my street stuff at 400 IS0 even in bright sun and to be honest its hardly a problem and the extra speed comes in handy.

Not so good for flash though since the shutter speeds shoot up but there are work arounds if you don`t mind a bit of flash clipping.

Like yourself Paul, I generally shoot all of my outside stuff at either 200 or 400, regardless of how sunny it is as I find that the faster shutter speeds are useful.
I never have an issue with noise.

Old habits die hard, back in the film days I preferred the slower films on dull days, and the higher ISO films on sunny days Smile
