I question the durability of the Sigma low end zoom lenses. We have two Sigma lenses (18-125/200mm) that got stuck in aperture f5.6 / f22. I somehow managed to free up the first one. The second one, however, is plain dead. Some of the connectors are wandering around between the lenses so I guess this is it.
So which one is better in term of durability for a low end zoom lens? Canon, Sigma or Tamron? I don’t know what duration I should expect for such lenses. They were both 5 years old. I will give a try with a Tamron 18-200mm Di-II instead.
