>>4387277Yeah for birbs (and many quick moving animals/mammals) you want more like 1/1000th ideally. They twitch fast AF and you'll have a better chance of actually stopping their motion. Yes that means higher ISO. Yes that why birbing gear is typically the most expensive with their fucking huge apertures on 600mm lenses (so they can widen aperture instead of raising ISO).
High ISOs can be NR'd or AI'd, and you can always resize to a smaller res to help hide the noise, but you can't really unfuck motion blur for having too low a SS.
>pic rel is a heavy crop so IQ isn't great, but no motion blur!
