If you take $790 and consider what that must pay for, it becomes a bit difficult to believe that this lens can compete with the Otus in any way.
You do realize that Canon pays around
$300 to manufacture a $2400 MSRP lens right? The manufacturing is not what costs a lot, it's the initial set up and the R&D and marketing and prototyping. Canon has huge overhead from millions of dollars poured into research, design and manufacturing facilities.
(If memory serves me right) 10 lens elements, of which 3 are SLD and one aspherical, a fast reliable AF system, housing, hoods and caps and casing and profit ... I fail to see how it is possible to produce a high quality product, with tolerances to compete with L-series, Otus and others, for that money, no matter how efficient you are or how cheap your labor is.
I'd be delighted if they prove me wrong. That would make this lens a significant game changer!
It doesn't matter what you think. This lens has ALREADY been proven beyond a shadow of a doubt to be twice as good as anything else with autofocus period. We have raw data, we have prototypes that have been proven to match the raw data, we have the lens' design data that has been verified as capable of providing the performance etc etc.
This lens makes anything else you can buy in it's class that has autofocus completely obsolete from a performance standpoint. We're talking the same difference as Tamron 18-270mm vs 24-70mm f/2.8 L II. It's also set to have amazing bokeh, being designed to mimic the 50L f/1.2 and low color fringing and hazing so overall it should be better in every way than competitors.
