I took out the Nikon f4 for a test drive yesterday. This is an amazing picture taking machine. It is a big bulky massive camera. Operating it is very similar to older mechanical cameras, you have to set the aperture on the lens there is a shutter speed dial. I set in aperture priority and almost forgot to check the shutter speed before taking a picture. I used aperture priority for years and I was most comfortable with that mode yet I have been using full program with digital. They big full bright viewfinder is always great to work with. Now we have to wait until I get the film processed to see what I captured. There is always a revelation when you spread it out on the light box. We will have to wait and see.
