Thanks, Glyn, KeefyB, and rockhopper.
At the risk of labouring the point, I'm more interested in it's effect on the headlight than on handling. Realistically, on cold, dark, winter roads, I'm much much interested in simple A to B transport. I'm certainly not going to be exploring the limits of its handling in rush-hour traffic coming home from work.
But it's a relief to know I'm in the right ball-park with 18 mm.
I'm thinking of braving the cold and shooting over to Bath in a bit; the annual Film Festival is on at the moment.
