Originally posted by vivavegas Thie high ISO shots do remind me more of a "film grain" then noise. Kinda of has that grain characteristic that Im used to when shooting with my RZ67 using Portra 400 (rated @200). Of course id never dare shoot Portra 400 @ 6400...lol.
i used Portra 400 @3200 ISO (+3 stops) for some sports competitions.
There is some color shift in the yellow or mageta spectrum, but the result ils quite good. Grainy, but noise free.
I have no fear to use it if the subject is properly exposed.
