I use a couple of Manfrotto tripods, an ancient 55B when I am out and about but not walking to far, and a 190 when I am walking. The 55B is a beast of a 'pod and when equipped with a B&S head plus the hexagonal quick release platform adapter it is faultless.
I always thought Tiltall was made in conjunction with Leitz(?) I have a book where the Lieca Reflex series is discussed and examined where there are used including a superb Tiltall monopod which I have a sample. Ideal for use at places like air shows and race meetings.
