Will go and test this right now.
Edit: Either I'm going insane, or my K-5 won't go to 4500 ISO? o.o
Edit: Scratch that, have to be in 1/2 step mode as opposed to 1/3
Semi-Conclusion: Yup. Seems sharper on my LCD for sure.(With NR disabled at least)
Final Conclusion(Mine at least): Seems as though the "Noise" gets less noticeable due to it becoming "Smaller"? Don't know what would cause it, but it's noisier at 4500, just looks better because there's less pixelation style noise.(?)
