The Acratech Long Lens Head is designed to support super-telephoto lenses as long as 600mm f/4.0. The CNC-machined Long Lens Head weighs less than 1 lb and features an Arca-style quick-release clamp that's compatible with plates from manufacturers such as Arca-Swiss, Kirk, R.R.S., and many others. The clamp is indexable, which means it can be rotated in 90 increments by loosening the rubberized knob. This enables easy use of cameras without lenses that have lens collars, and facilitates 90 sideways tilt (rather than front-to-back tilt).
