I know some of you are curious of Nikon D3 ISO performance, so do I when I got mine. So I tested some few shots. All photos shot in RAW(NEF) file then convert to JPEG. Camera setting set to Auto White Balance, no Flash, normal noise reduction, no further noise reduction was done.

I handheld shot these 2 macro photos. Is hard to get sharp photos without the help of VR and high ISO of Nikon D3.

At this setting, roughly you would know how dim is the light.

I can set ISO up to 3200 and use the photos straight out from camera without having to do further noise reduction. At ISO6400, photos are abit noisy, but still bearable. Both the new lens are truly gorgeous. Fast focusing and produce sharp images. Nikon D3 outdoes my expectations. White balance is very accurate, very fast focusing and amazing ISO performance. With the 2 new lens, the combination is truly remarkable.
