I recently purchased the 70-300 ED Nikkor zoom lens. I noticed in David
Ruether's subjective lens review an entry concerning this lens. In it David
said of the 2 lenses tested both were moderately defective. This turns out
to be a problem with film-lens parallelism. When panning across a distant
subject it produces a slight focus shift. I noticed that when the lens is
zoomed out to 300mm you can grasp the lens barrel and the zoom ring and try
to wiggle it. The barrel moves side to side in relation to the zoom ring.
Has anyone else noticed this on their lens? I haven't used the lens very
much so I don't know how it affects images. I recently converted from
Minolta to Nikon because I owned older lenses and couldn't use them on
Maxxums, so I said goodbye to Minolta. Nikon is smart to keep the F mount.
I've only owned one other zoom lens, a Soligor 35-105 macro. It turned out
to be a piece of junk. I hope the Nikkor isn't. Thanks for information in
advance.
