LensAlign
Wondering how to make use of the microadjustment feature of your new Canon 5D Mark II or Nikon D700? Michael Tapes has put together the LensAlign. I have used his WhiBal for years and, based on the reviews from Michael Reichmann and the guys at Imaging Resource, it looks like a solid, accurate tool. There are videos from both Michaels on their sites showing how to set it up and use it.
Cost? US$139.95 for the LensAlign Pro that ships by 16-Dec-2008 and US$79.95 for the LensAlign Lite that will ship in January. Differences? The LensAlign Pro is assembled, has a tripod socket, and red bulls eyes for lining up the sensor plane with the target. The LensAlign Lite relies on the use of a mirror to do the alignment.
