Previously in ML I could override the ISO to above 3200 on my 500D when shooting stills.
Now, that option only seems to work in Video mode?
I found this out after travelling 200 miles to do some astro-photography. Needless to say, my plans for nice deep starfields didn't plan out with the Canon 3200 limit

I saw no mention of this change or why it has changed. I want to fix it but am unsure where in code this was done?
Could somebody point me to the right place to re-enable ISO override for normal shooting not video.
