Few weeks ago I drop my brand new Tamron 24-70 f/2.8 and the filter gets irreparably stuck to the front. Calumet (the bold guy) did a great job of taking it out in 24hrs - at exactly one 4th the price I was quoted in another shop. Little additional story. Due to the drop, the coating got a bit scratched - a tiny thing, irrelevant, but still a nag on a lens bought 2 weeks before. Or so I thought - wait till the end. So, I come back home after the filter was removed, I check the lens and.. the front element is crystal clear. The scratch? Gone. That's impossible, right? You can't re-coat a lens. After some thinking it dawned on me: they had removed the coating (and so also the scratch). Crime!! The coating is an essential part of the lens, and it was 99% perfect before I brought in the lens! And this guy removes it without even telling me?!?! I felt really, really let down, so the morning after I go back to Calumet to complain. Damn hell! And so what? It turns out the coating is still there (of course: removing the coating is not an easy job). Only, the lens had been cleaned to a better state than it had even been. And the scratch wasn't a scratch, most likely just some dirt. Bottom line - this was a bit of a humbling experience, but with a good end. The lens is now almost better than new. And the whole service was done for a very, very reasonable price. If I can stand the embarrassment of showing my face there again, I'll use Calumet again.
