BH-55: The heavyweight ball head, top of its class in terms of lock-up strength.
Who's it for?
-Any photographer who demands the frame of a composition be preserved and resistant to drift and vibration under any circumstance. - A fine-art photographer who shoots still subjects at slow shutter speeds for long-exposures. - A landscape photographer who works in the elements with very narrow apertures for maximum detail and DoF. - A product/food photographer who focus brackets using an ancillary macro slider. - Any photographer using an effective focal length greater than 400mm on a fixed, unmoving subject. - Astro-photographers and astronomers. - Studio photographers who rarely move their tripod. - Any photographer who does not mind managing a 2lb ball head for the sake of rock-solid rigidity and lock-up strength to obtain the sharpest image quality possible.

BH-40: A lighter, mid-size solution which still features independent panning base and/or drag set control.
Who's it for?
- A traveling photographer seeking a lighter alternative to the weight of the BH-55, but still requires a robust head for stationary subjects. - A photographer who will not use lenses that exceed 400mm in effective focal length, and if so, are agreeable to using higher ISOs and/or wider apertures in order to keep the shutter speed fast enough to avoid soft images resulting from lens vibration.

BH-30: A small but robust ball head with an independent locking knob for the panning base.
Who's it for?
- A photographer primarily on the go, who barely stops moving longer than it takes to click a shutter. - A travel photographer whose mobile support system must be balanced with ancillary pieces of gear and baggage. - A street photographer who primarily shoots handheld but may need to use a tripod occasionally for portraits, low-light moments, scene setting, or cityscapes. - A photographer working with glass no longer than 300mm in effective focal length.

BH-25: An ultralight ball head for specialized small-gear support applications.

MICRO BALL HEADS
BC-18 & BPC-16: Surprisingly robust despite their extremely compact profile
Who's it for?
- Useful for cameras ranging from mobile phones, to compact “action cams” such as a GoPro, to point-n-shoots, to full-size cameras with prime and short zoom lenses. In addition, the micro ball heads can be used to support accessories such as monitors, mics, flashes, remotes, etc. The BPC-16 features a 360-degree panning ring, whereas the BC-18 does not, but has a stronger lock-up.

PG-02
The essential head for photographers creating stitched-frame panoramas; the full-size Pano-Gimbal head allows for both horizontal and vertical rotation to create a multi-row panorama image. In addition, the PG-02 is also a robust and capable gimbal for smoothly tracking moving subjects when shooting wildlife, sports, fashion, and portraiture.

FG-02
The Fluid-Gimbal head is identical in appearance, operation, and application as the Pano-Gimbal head, but features internal fluid-damping that provides for adjustable levels of resistance on both the tilt and pan axes. Ideal for cinema applications where delicate control of track/pan shots are essential, the FG-02 is still recommended for still photographers who desire a personalized feel of operation when shooting in different circumstances.
