I had the delightful opportunity to go out shooting with good friend and Nikon NPS rep Joseph Carey over the XMas break. He brought along the drool-worthy Nikon Df and a sweet selection of Nikon glass I have not had the opportunity to shoot yet What a fun opportunity.
Joe brought us to an abandoned location he has shot previously and we went to town as dusk settled in...
First thing I did was to run an exposure test from ISO 6400 down to the native ISO 100. I didn't go all the way up because I was interested in the 6-stop High Exposure Test and discovering if there were noticeable quality differences on the way down to ISO 100.
Looking closely at the scene I chose, can easily say that this camera body surpasses my D700 in reducing noise in higher ISOs. It should - it has the D4 sensor in it! But keep in mind the temperature was around 36 degrees Fahrenheit – ideal for full-frame sensors doing longer exposures. (The higher the ambient temperature, the harder time a sensor has keeping hot pixels out of the RAW file.)
All below shot with the AF-S Nikkor 35mm f/1.4G manually range focused because I forgot my high-powered flashlight (smacks self in head). Click for fullscreen to see the ISO, time and F/stop. NOTE: This uses a manual cable release, so the timing was not to-the-second perfect. But I was darn close!
