Why not wide open in P mode with flash?

[QUOTE="Ben Taylor, post: 616533, member: 42948"] Ok, interesting that auto ISO doesn't behave as expected and thanks for the link, but that can be eliminated. (For the following test I have the 24-85 f3.5-4.5 on, zoomed right out thus wide open is f3.5) Turning auto ISO off and just setting ISO to 800 in a (very) dim room, without the flash it meters at f3.5, 1/6th. But pop the flash up and it meters at f5, 1/60th, and underexposed. Can understand 1/60th as that is the minimum shutter speed with flash setting, but why f5 target than f3.5 if underexposed? The conclusion I'm drawing is that P mode is not good in dim light and is only really useful when you want to [I] limit [/I] the amount of light coming in and you want tree camera to choose the combination of narrowing of aperture and shutter speed do it by. But other interpretations welcome... I'm quite aware also that some people's natural instinct is to set ISO manually, possibly because they use/used to use film cameras, whereas another school of photographer the ISO is last on the list of the variables they want to set themselves. I come in the latter camp. I always read the exif on Flickr and you often get photos with unnecessarily fast shutter speed, say a2000 th for a still portrait, but higher than base ISO. The only possible reason is the photographer has set ISO manually I guess? This is one reason I like nikons max ISO/ min shutter speed settings. [/QUOTE]
