Just wondering, but do 90% of the people who ordered the Sigma need the lens straight away for some big assignment? Because it does look like the 90% of people are are just a bit too impatient.
What's your point? I think that's obvious, but to answer your question, yes I do need it for an assignment and I'm impatient.
My point is that it's just easier to relax and wait for the lens to be shipped.
This thread is directly addressing any additional information that can be shared as to the wait in dealing with back orders. If there's a possible 2 month+ wait for gear that you need for a job in less time, then any additional specifics will help in your decision to wait or find a replacement locally. Your subjective contribution to people being impatient as I stated before is clearly obvious: people are impatient waiting for any new and hyped up piece of gear. Bringing that to their attention is redundant.
