Canon & Nikon 500mm f4 lens samples

The  500mm f4 prime lens is a really great compromise between weight & focal length compared to the heavier 600mm f4 prime lenses. The 500mm f4 are generally much lighter to hand hold and the loss of  100mm is not too significant.  Here are some samples from our rental Canon 500mm f4L IS & Nikon AF-S 500mm f4D lenses.
