I had purchased a MLG for Nikon D90 and was very impressed with the detail and depth of the information. Great info on what lenses do what, what settings to try where ans all around a great addition to my camera that I eventually bought.I already had a D70s and thought "might as well get an MLG for it too". What a disappointment. not as good as the Nikon manual that came with the camera. A complete waste of money.I do not recommend buying this unless you can't find a Nikon manual for your D70/D70s.
