It does look like you could attach a plate or foot to the lens but then without a collar you could not rotate the camera to adjust for leveling or to take a vertical image.

Perhaps the designers intended for this to be a hand held lens primarily but at f/11 I would think some slower shutter speeds will come into play which would need a tripod or is the IBIS so good as to eliminate the need?

Also for wildlife (especially birds) using a tripod for long sessions in a blind is a necessity.
