D700 High ISO Performance

This photo was shot with a Nikon D700 with AF Nikkor 85mm f/1.4D IF lens at f/2.5, 1/6400, ISO 200, in camera High ISO Noise Reduction off.

This photo is shoot with the same Nikon D700 with Nikkor 85mm f.1.4D IF lens at f/2.8, 1/200, ISO 3200, in camera High ISO Noise Reduction on.

D700 uses the same full frame sensor as its more expansive sibling D3.  DxOMark ranks the image quality of D700/D3 higher than most other DSLRs, only surpassed by the newer Nikon D3x and D3s.  One of the reason for the high ranking is the high ISO performance.  The high ISO performance not only means that we can shoot at lower light, but also means much better image quality in the shadow.

Although I shoot my D300 routinely at ISO400, but even at that ISO, I feel I am pushing it.  For D700, I routinely shoot at ISO640 without any problem.  The Nikkor 85mm does not have VR, thus I have to watch out for my shutter speed, not letting it to go too slowly.  An image shoot at higher ISO with higher noise is still better than a blurry image due to slower shutter speed.  Thus, with the 85mm lens, I set the auto-ISO between 200-6400 with minimum shutter speed at 1/100 (1/200 for Grace).  Since my new iMac and MacBook has much better processing power, I let the in camera High ISO Noise Reduction on.

The first picture was shot at outdoor under bright sunshine by me.  Grace took the second picture indoor.  It is incredible what a modern camera can do.  We do not see any significant difference of noise between the two pictures, even though the second picture were shot at ISO3200!!
