On the other hand - let's juggle that for a second - there's new Canon RF 28-70 F2 that is just under 1.5 KG and is priced at $3,000. Could one make an 18-80 at F2.8 or something similar in the same price range? With the ever increasing low light performance, acceptance of full frame and falling LED light prices, this ought to be within the range of possibilities.
