A 24-105 which completes my zooms (at least for some time)--I must have been good this year. However, the lens is defective--hmm, maybe I wasn't so good. There is large piece of dust or air bubble in one of the elements. Even though I've read multiple times on this site that dust and these minor defects do not effect IQ, the lens is going back for a replacement. I'm not paying L money for a defective or QC problem lens.
Now time to work on primes
I'm pretty sure I was told that the tiny bubbles are a sign of quality glass, I'm pretty sure a few of mine have them and they work beautifully.
This has got to be a hoax or else my 16-35L, 70-200L, and 100 Macro L are defective because they don't have air bubbles/dust in them. Yes I've read this too but don't buy it. So is there any evidence that air bubbles are a result in a HQ? I know that bubbles in them self aren't HQ but I suppose the process to make a HQ lens may sometimes result in air bubbles. Maybe that is the HQ part.
