Comments about AquaTech AquaTech SoftCap Element Guard for Nikon 300mm f/2.8 Lens:

I had no problem with this cap and it replaces the crazy cloth sack that ships with my 300 2.8 VR lens. I found it fit snugly but the added benefit was that it created a pocket of air under the cap which provides extra protection.

This is an outstanding item and very well designed. If the other poster took 20 seconds to fit it in the end of the lens he would find it works perfectly.

I buyed this softcap for my Nikon 300mm f.2.8 Ed IF but it does not fit. It seems too small. I asked to acquatech for a replacement but I had no answer.
