The INDURO GHBA Gimbal Head is ideal for photography involving long, heavy telephoto lenses - in sports or nature photography, for instance. Working with a long lens on a standard ballhead or tilt head can be a real struggle, distracting you from the photography. The gimbal head makes the camera and lens seem almost weightless, with vertical and horizontal tracking of moving objects becoming relatively simple - a feat not possible with any other support system. An Arca-Swiss-compatible quick-release plate is included. Fits Arca-Swiss-compatible QR clamp on a heavy-duty ballhead.
