If it were not so hard to handle you would find it in almost every industrial or consumer product. I remember the contortions the Chem E's went through to get titanium reaction vessels specified for some interesting reactions at the pesticide plant. Instead of weekly maintenance in a very high risk environment we went to annual inspections with most of the interest in the seals and valve seats. If a lens was designed for a titanium mount from the beginning, I think you would see a much smaller lens, just a much higher price.

Unfortunately, as someone pointed out earlier, it requires special tools and skills to machine it properly. It is extremely tough. Jim Nichols
