This is part of the reason I waited to order. Once I do get one I can already see that I need to set aside several hours of testing to see if it lives up to what I the performance I would expect at $2300. What is frustrating about this is that most of us do not have the resources and tools that Bryan has to test. For instance my tests would all be 24x70 vs the lens I own now that I could compare to, to see if I was getting comparable performance.
