The Acratech GP-s Ballhead with Lever Clamp is an updated version of the existing GP-s 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-s 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.

With all that functionality, the GP-s Ball head is designed with a small base diameter of 2.08" to allow it to be used with travel-type tripods whose legs fold up 180°, reaching to the top of the tripod head. The smaller base diameter allows the tripod legs to fold more compactly.

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 0.9 lb, the GP-s Ballhead supports loads over 25 lb from any position, including tilted 90° and mounted upside-down.

Fits all standard tripods (1/4"-20 and 3/8"-16 threads)
Easily holds over 25 lb (11.4 kg) at any angle
Works as a gimbal head with lenses up to 400mm f/4.0
Weighs 0.9 lb with quick-release clamp
Reduced base diameter of 2.4"

Full movements in any camera position
Precision machined aluminum
Compatible with Kirk, Arca Swiss, Acratech, R.R.S., and many other quick-release plates

Long-lasting stainless-steel hardware
All knobs are secured so they cannot vibrate loose and fall off

    I really like Acratech's design in their GP ballhead line; I happen to be one that values form almost as much if not as much as funtion in most cases. And this is the kind of product that balances both. The only reason that I didn't give it 5 stars is because the panning lock at the base doesn't have enough torque to positively lock against the kind of leverage a person can apply when, say, screwing or unscrewing the ballhead onto or off of their tripod legs. Dont' get me wrong, it's plenty strong enough, but when giving it a good snug cinch down during the install, it slipped on me just a little. Now, in its defense, I might have been tightening more than necessary. And I might also have failed to tighten the panning lock enough (I don't want to strip any threads so I just snug it down slightly more than "finger tight"). This might not be the case on the full size GP; I only have a GP-s so I can only comment on its strength. Otherwise, it's an incredibly capable ballhead that also offers a lot without requiring a lot of weight to be carried around.

    So, my review is going to be a bit differing from what I see / saw here when I bought this. What I was looking for in buying this was a head that is stable, easy to adjust and lock on to a composition, and strong. This head delivers in terms of strength and ease to adjust. Sturdy / easy to lock on to a composition not so much. To be fair, perhaps I expected too much from it. I bought this to take shots of the blood moon 4/4/15. What I found in usage today is that when I framed the shot I wanted and then tightened the ball down once I let go of the camera, the composition would drift *drastically*. This drift wasn't from slippage, but rather from play in the head itself. To be fair, perhaps I expected too much from this (I like to think not as close to $ for a head is expensive to me). I was pretty disappointed in the results, but perhaps you have a much lighter setup than I tried and this might work better for you. I can assure you that it is pitiful with a camera and lens that is well less than the max weight it is supposed to support. I had a lens that is a beast at 6.3 lbs (a tripod ring of course which is where I mounted to the head) and a camera that is no lightweight either (3.37 lbs). However, combined they are a little under 10 lbs which is well below what this is purported to support. Overall I'm disappointed and had I bought this on @ where there is a longer return period I would return it. Before the next blood moon in Sep/15 (and perhaps last that I will see in my lifetime), I will be getting a geared head like the Manfrotto 405 - hopefully that will meet what I'm looking for. Not being able to accurately frame a shot and tighten things down without it totally loosing the composition when the camera is released is a major downside of this thing in my mind.Pros: Seems to be built strong, easy to use, the quick release on the model I got is nice, movement such as panning is quite smooth.Cons: Biggest (and my primary complaint) is that you frame your shot, tighten things down and then when you let go the shot composition is totally screwed up because it shifted way off. Another thing for folks with an Arca setup to know is that while this does have an Arca mount, the mounts on your other things may not work without doing things like removing the stop screws (which I had to do for the lens mount) - however, perhaps that is offset by the spring loaded pin that is built into the base which does the equivalent of the stop screws I'm talking about.

    Upgraded to the Arcatech over a Sirui ballhead that I was using. What I like about the Arcatech is once you set it it stays. No drifting, no repositioning, nothing. Rock solid and it should be for nearly $. Great addition to my photography gear.

      Comments about Acratech GP-s Ballhead with Lever Clamp:

      I bought this to use on a Gitzo GT2542T Series 2 tripod and it fits well, allowing the collapsed tripod to close almost entirely around the ballhead. The GP-s ballhead itself seems really well made despite its light weight, locks down well, does everything it is supposed to do and can function as a gimbal head. Much superior to the more moderately priced ballhead I already owned which tends to drift in position when you tighten it down so that you had to compensate as you tightened. The GP-s locks where you want it. A really good mate for a top quality travel tripod.

        Well-made, light weight, yet powerful, this ballhead does it all for me. The head functions perfectly as a gimbal for my 100-400 F/4 lens. The action is smooth and balanced.
        When not using the head as a gimbal, it locks securely in place with no creep.
        Be aware that Acratech plates need to be attached to the camera or lens with an allen wrench and the screw is not captured.

                Comments about Acratech GP-s Ballhead with Lever Clamp:

                I bought this before going on a backpacking trek in New Zealand. The main decision was either this or a RRS 40 BH40. I chose this because of the open design allowing sand, debris etc to fall out freely. I am very happy with my decision. This has worked perfectly. Will easily support a DSLR with a 24-105mm lens. I have not tried it with a longer 70-200 lens, but have read that it would work.
                The built in bubble level works great. I have only inverted it a few times to be able to pan parallel to the horizon. Nifty feature, but just takes time to do.

                This was paired with a feisol CT-3442 and they work perfectly together. This head will allow the legs to flip back up around/over the ballhead for even more compact carrying.

                No regrets about this purchase. Solid construction.

                    This is my first ballhead from a monfrotto panhead. Wow!! much quicker to change directions and target your objects on the fly. To me, this is at the expense of camera stability. If you adjust too quickly without paying attention to the tension adjustment, your camera can fall to the side and cause damage.Remember to always tighten before letting loose your camera. Although this can happen with the panheads too, the panhead seems more stable with the larger zoom lenses. The acratech is much lighter, quicker to adjust, and easier to carry when packing for a long walk. I use it with my 7D, 70-300 IS USM on a Gitzo tripod. I have quickly made the change to a ballhead for most of my photos, and this is a nice one( I can't compare to others though, as this is the 1st one for me) I now use the acratech 90% of the time with the exception when time to set up, weight to carry, and weight of your equipment is not a factor. I really like this one!

                        Comments about Acratech GP-s Ballhead with Lever Clamp:

                        I use this with Gitzo Traveler legs. This head like the legs is a precision piece of equipment. Head locks solidly with little pressure. It sets up easily for panorama shots.
