It is quite possible to spend 20 minutes fiddling with focus / perspective. I, personally, don't typically do that all that much but it does take more than 10 minutes to go through the entire routine (set-up, focus, meter, filters, take picture. take another. knock it all down). But that's with a Chamonix, which is quite handy but has some screws where I would have put snap on connections.
