Thanks for the input. The lens has not been delivered yet but I wanted to be prepared when it arrives. On the 85mm f/1.8D, the screw on lens hood was too deep for me to use the lens cap that came with it. However, the Nikon 77mm lens cap was a perfect fit for that lens hood. I thought that I would have the same problem with the 24mm f/2.8D Lens hood.
