I have a need to do landscape simulations for a very large project under CEQA. The requirements are to shoot what is equivalent to the human eye. The accepted professional standard according to what I have read so far is a 50mm lens on a 35mm camera. I am going to use a Nikon D300 and need to determine what lens setting to use to get to the equivalent of the above setup on a 35mm film camera. I was told that I could get an 18-55mm zoom lens and set the focal length to about 32mm, which would effectively give me the right setup. Advice?
