But it would be nice to know the exact diameter at the base and the head, to see how well it matches up with tripod and camera size. The panning base flares out at the bottom and the plain/non-QR platforms look undersized on the larger heads, so it's difficult to tell what type of cameras they are intended for.
For that information, you can see our catalogue: http://www.flmcanada.com/flm-catalogue.html
