Hmm, with several products I made the experience a good repair is better than an exchange. What AiryDiscus tells in the lens detail thread leads me to the idea either playing good copy - bad copy roulette or let a good tech fix it. But since it's Australia and the lens quite new, I hesitate to believe there are already capable techs available for it.

 

Btw. in Europe each manufacturer has the right to choose "exchange or repair" for two times in such a case. After that it's money back time. This is generally spoken about consumer products.

 

Well, the usual strategy is to claim that the thing is within specs. Thereafter you are alone. Here, in Europe, everywhere. A joke.

 

As mentioned before I highly doubt that most lenses are even designed to be serviceable.
