I've looked around for a couple of all-in-one zoom lenses, and my question is: Why no zoom lenses with f-stop ratings in the 1.4 area across the entire zoom range?
I see lenses that are 70-300mm w/3.5-5.6 f-stop rating and such. Would the lense end up being so large that it wouldn't be use-able? Or would it be the cost?
