Man, is putting a lot of work into these tests. I am impressed by the methodology and its real world emphasis.

Impressive! The retailers won't do this type of testing for obvious reasons. Others, like Photozone, can't get enough copies of the lenses. A lens rental business can do this with no repercussions from the manufacturers. He isn't getting paid to blog this, but I'll bet it will be a Trojan Horse in that the business gets a better following. Note: I've used Lens Rentals before and am not associated with the company.

I believe they sell their used stock from time to time. Having this data on hand would certainly ease used purchase anxity. Hell, there would be a market in buying in bulk, testing, then selling a "tested" lens at a premium for those that don't want to play the exchange/warrenty game with other retailers/manufacturer.
