It is not a good thing to have your lens refuse to work when you are on the trip of a lifetime. It was a pretty desperate phone call from a good friend who was vacationing in Hawaii.
I went through all of the usual things to do that will usually bring a lens back to life. He tried them all and none of them worked.
Before he called me, he tried to find a camera store that could rent him a lens, but in his remote location, no one had what he needed.
Fortunately for my friend, I was able to find two lens rental companies that could get a lens in his hands the next day. But that’s not the whole story. There are good reasons other than emergency equipment failure to know a good rental company. You can read all about it in this article.
