Neil, thanks for the helpful response. I think my problem is a combination of vibrations and getting a focused image. Because the LV image is vibrating I can't see the subject well enough to fine tune the focus. It's a little easier on my D300 because I have a Katz Eye with a split prism. However, they don't appear to make one for the D3 due to metering issues.
