I had a friend come over last night so I could test out this new camera properly. I think I'll keep it.
100 ISO, 1/100 @ f5 on FA* 85 f1.4 - no sharpening was applied, only a bit of color correction and a slight adjustment to exposure and shadow (very slight).
100% crop...
The only downside I have run across so far is that this camera might require me to do more retouching since it picks up more detail than us typically wanted in a portrait. Oh, and those aren't hot pixels, Dawn was wearing a bit of glitter. I lit her with a silver umbrella, which gives more specular highlights than a white one, so that I could push the camera. Not only was I impressed with overall image quality, but the shadow areas are very nice. Better than my K10 in the shadows.
