I think the foot will be included. I've seen Canon product shots before where the foot was missing. Not sure why they do that but I'm fairly certain these will come with a foot and a lens hood. The lens hoods already have a product number. If the lens hood is optional like non-L lenses in the past then Canon is surely cheap.A foot might be an optional extra. F11 wouldn’t be enough for serious animal/bird photographers but if it were sharp it might be popular with beginners. It looks push pull so if there is no sealing it will be a dust magnet. I think it’s an interesting design choice by Canon. I’ve a 600 F4 II and it’s a whopping great lens. Not exactly something you take on holidays. A lot of airlines have a 7KG limit now for cabin luggage.
All N. American airlines have removed all weight limits from carry-on so I've found it easier to travel with heavier gear in recent years.
