In the past maxiumum f5.6 was tolerated for a zoom lens with very few exceptions that was when ISO 400 film was considered high ISO.
Today with higher and cleaner ISO becoming available we are seeing canon launching two f7.1 zooms
while 100-500f4.5-7.1 is a very reasonable offering 24-105f4-7.1 seems odd.
