I don’t think its a DoF issue, unless they are not in straight line and you are on 4 or 5.6, distance dependent.

Also – 18-200 is not the sharpest peanut in the packet, and can be softer towrds the edges than the centre. Your 5D uses a full frame sensor so is less forgiving of this, all the lens area is used and not just the inner 60%. Soft edges which will not show on the 350D will on the 5D.
