Nikkor lenses tend to have high contrast. I have found that 1/2 to 1 stop of overexposure has saved a lot of pictures. The colors tend to saturate, and shadow areas come out somewhat dark using "normal rules". Experiment some, and try both the 1/250th to over-expose and 1/500th "sunny 16" rule. I use a Weston Master II meter, and measure the subject up close. If I meter the whole scene, I tend to open up 1 stop from what is indicated using the accurate 50 year old meter. With a Summarit, lower contrast, I do not do this.
