I use auto ISO a lot, especially when out and about sheeting 'on the fly'. It's great for keeping shutter speeds where you
want them relevant to the available light etc. However, I've recently come across issues when using auto ISO with flash (I
don't do much flash photography) as I've found that the camera sets the ISO based on the ambient light and ignores the
fact that there's a flash about to be used. I've recently had some images being shot with flash at ISO 6400, with some
resulting loss of IQ. Is the answer to set the ISO manually, meaning I will need to set the shutter speed manually too?
