Great article! However, I do have one problem. At what point did we decide that a $1500-$30000 lens shouldn't be "almost" perfect?I am sure there are those out there that think even $1500 is not a lot of money, but I'm not one of them! What ever happened to pride in workmanship or QC? Not to mention when did it become acceptable to spend this kind of money for a crap shoot (pardon the pun)? What if you can't afford to buy 3 different $5000 lenses to even try to hit a good lens? Are the tolerances displayed here something that should be acceptable? Yes, I do think I should be able to feel comfortable that my "only" $1500 lens will come to me in usable condition. If they can make one, they should be able to make sure that the odds are better than they apparently have. Buy the way, I would be willing to pay a reasonable price to have a new lens shipped to you first for a bench test before coming to me. No offense, but it is sad that I would have to go to this extreme to begin with.
