I had one lens with a bubble and then different lenses with clicking when I tried to buy this lens last fall. Since I could only vote once, I voted for the bubble....

In past years, it was common for some of the better glasses to have bubbles. Some glasses with highly desirable optical properties couldn't be heated to a high enough temperate to become fully fluid so that bubbles would naturally escape. At one time bubbles were even viewed by some as a mark of quality. Now glass technology has advanced, and sometimes platinum crucibles are used, so bubbles are no more. One or a few small bubbles will have negligible effect on your images.

I think you've been had by a troll.


So I guess your tally is 0.

I almost kept the lens with the bubble. It was great in every other way. The rationale for returning it was pretty simple, 1) shouldn't have a bubble, and 2) I know me, and if I were to ever sell the lens, I'd let any potential buyer know that there was a bubble in the front element, which could kill the resale value. So, I do not regret my action. It had nothing to do with trolls.

But I did receive 4 other copies of the lens with the clicking sound, so no, even if you discount the bubble lens, my tally is not 0. :)
