High ISO's when taking flash pictures

edited April 2012 Posted in » Nikon D5100 Forum
Howdy Everyone. Every time I take a picture using the built-in flash on my D5100, the camera raises the ISO to the highest limit (usually 3200). I don't like to go beyond that point. I suppose it's because I'm using Auto ISO, but I'd like to know if that's normal or if I'm doing something wrong? I don't think it's normal to have the ISO fixed in order to take flash pictures. Regards - Miguel

    Howdy @Moose - Thanks for your reply, and sorry for not having answered sooner. I did try with resetting the camera when I noticed the problem with the ISO, but nothing happened and the problem remains. I usually use Program mode (P) so my flash pictures are always in P mode and after resetting the camera it keeps using the highest ISO available in the AUTO ISO mode.

    I'll be using your suggestion and adjust it to a lower ISO before using flash. What bothers me is that with my old D90, I never had this problem. I always used ISO 800 in my flash pictures, even in good lightning, but it never raises to an ISO beyond that.

    Many thanks! Best regards - Miguel

    I have to agree with @nileugim. If you have the camera's mode set to Auto it will ignore the maximum ISO setting and take everything at ISO 3200. The camera is excellent in mode P, but with the mode set to Auto with flash in low light the photos are sadly unusable.
