This is three years after buying a product, unlike the many immediate reviews. Bought a Sony-Zeiss objective for a hefty price tag, but noticed later on that humidity condenses between the lenses and, after evaporating, fogs them until cleaned.
After opening up the thing and cleaning it up, I needed one spare part to restore the objective. Called Zeiss: "Can't help you. Can't provide you with factory number. Go to Sony."
Called Sony: "Can't help you. Go to company X, which handles these in your country."
Company X: "Can't help you. Check out catalogue for spare parts."
Catalogue: "Don't have $#*!."
Another example of bureocratic bull$#*! From three different companies, none of which want to do their thing. Ended up trashing the objective. What pisses me off the most is that the factory number could had been given easily, even tracked on importyeti.com for US imports, but they refused.
