Product Highlights
  • Functions as a Gimbal Head
  • Functions as a Leveling Base
  • Lever Quick Release for Arca Style
  • Dual Laser-Engraved Degree Markings
  • Supports Over 25 lb
  • Lightweight - Weighs Just 1 lb

The Acratech GP Ballhead with Lever Clamp is an updated version of the existing GP head. Rather than a rubber knob, this model features a locking lever for securing the Arca Swiss-style clamp that constitutes the quick-release element.

Featuring first-class construction, the GP Ballhead also functions as a gimbal head for lenses up to 400mm f/4.0, and it can be positioned upside-down to function as a leveling base for panoramic photography. Even if you're operating on rocky or otherwise uneven terrain, you can pan absolutely parallel to the horizon, so you won't need to carry a separate leveling base to create accurate stitched panoramic imagery.

The ballhead also features a bull's-eye level on the quick-release clamp and a detent pin, which prevents the plate and anything attached to it from sliding out of the quick-release clamp when it's partially loosened. Lightweight at only 1 lb, the GP Ballhead supports loads over 25 lb from any position, including tilted 90° and mounted upside-down.

        Comments about Acratech GP Ballhead with Lever Clamp:

        I also have an ultimate ball head which I use with a Nikon d7000 and Gitzo tripod, which makes a great light weight and very sturdy combination for all my lenses. Have not taken the GP into the field yet, but it seems to have the same weight and size pro's of the ultimate and I expect will be a little easier to tilt up/down because it does not have the angled grip, and has the advantage of being like a leveling base for pano's if set up that way. It's a very well made product.

        This ballhead is worth every penny! The machining and build quality is second to none. A well thought out open ball design that is rugged and yet easy to use. And all this... at 1lb, fantastic.

                  Comments about Acratech GP Ballhead with Lever Clamp:

                  I didn't understand how this ballhead was used for the gimbal action that was described in the product literature. It seems that by adjusting the tension on the ball - not with the release knob but with the tension knob - that you can dial in just enough tension to allow some movement with sufficient force. You can get off a shot like this but you'd have to lock it down if you really want the maximum benefit of the ballhead.

                  The locking mechanism on the lever is wonderful - better than I was anticipating.

                    Comments about Acratech GP Ballhead with Lever Clamp:

                    I have owned this head for a few weeks now and have had the opportunity to use it for landscape photography in the local desert. I am glad I chose the lever clamp rather than the standard screw clamp because the lever feels distinct from the other adjusting knobs; thereby enhancing camera security and preventing accidents. If you are like me, when working you don't always look at the knobs when adjusting the head and composing the shot. In getting used to the head it is easy to confuse the knobs. The lever prevents you from loosening the camera by mistake.The GP Ballhead is fine quality, sturdy, and provides great range of motion. (So far, I have used it only for a camera with a standard lens, not with a telephoto lens.) The tripod I am using allows the central post to be placed horizontally for low-down shots close to the ground. Such configurations in which you shoot horizontally with a horizontal post require the tripod head to have a wide latitude in positional adjustment, which this head does.I discovered that I must be careful when mounting the GP head to my tripod, which has 3 setscrews to prevent the head assembly from rotating and loosening on the tripod. If I tighten those setscrews too much, the base of the GP head is distorted, causing the GP adjustment in azimuth to bind. Therefore, only minor tightening of the setscrews is permissible.Acratech warns against carrying the camera while still mounted to the tripod head. This is good advice, but it is not always practicable to remove the camera when moving a matter of feet. Be sure the knobs are very firmly tightened or you may have unexpected & uncontrolled camera movement as I did. This would probably happen with most heads, given the right circumstances; so I do not view this as a shortcoming of the GP Ballhead.

                        It works as advertised. I used for the first time last weekend to photograph vintage cars. It worked great, easy to use, and it is nice to have the rubber knobs to control the head.

                            Like the previous acratech ballhead i used, this is a great piece of equipment. I like the security and quickness of the lever compared to the knob, major upgrade in my opinion.

                            Like the previous model also, my only wish would be that the leveling bubble would be visible once the camera is attached to the tripod - rather than hidden under the plate. It's a small thing really, but I find with the weight of my camera it's much easier to level the lightweight head than it is with nothing attached.

                            Flipping the head into panorama mode is simple, and there is a hex wrench included, but there is also a slot for standard screwdriver (or small coin) to loosen while on the go. I did notice there is some slight difficulty re-attaching the quick mount head to the ball going back from panorama mode, but I think this is just something to get used to - seems like there is one bracket that is larger than the others to help align the top, but it took the first few attempts to notice.

                            Very high quality overall, love the laser etching, and easily holds both my smaller and larger digital cameras (M9 / 5DmkII)
