Manfrotto 303SPH-UK 3415 Upgrade Kit, Converts a 3415 VR Head into 303SPH-like Spherical Panoramic QTVR Head.
In view of the growing demand, Manfrotto introduces an upgrade kit, to help photographers that bought the 3415 - the first VR head - and transform it from a single row to a multi row pan head.
The 303SPH-UK upgrade kit is essentially a 303SPH head without the 300N Pan Rotation Unit, or the plate attachment that locks onto the 300N. By using these components from the 3415 head, photographers can use their existing pan head as a basis to build a 303SPH-like product.
Remember that the 300N rotation unit has been improved compared to that supplied with the original 3415 family.
