Rather strange situation with ISO - K-5IIs has closer to nominal ISO at 80-100 and 3200-6400 (and e t.c.)
That is most interesting ogl
Thanks for posting this.
My prediction is that the added sharpness of the K-5 IIs will prove beneficial up-to a certain point along the sensitivity curve, at which point, the effects of noise may have an inverse effect on IQ.
OR WILL IT?
I guess there's only one way to find out.
I'll run a few tests today to see what comes out of it.
