Acratech GP overview

  • 1Description

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.

Works as a gimbal head with lenses up to 400mm f/4.0
Weighs less than 1 lb (0.45 kg) with quick-release clamp
Easily holds over 25 lb (11.4 kg) at any angle

    Acratech GP reviews

    GP Ballhead with Lever Clamp is rated 4.5 out of 5 by 36.
    Rated 5 out of 5 by from I love this ball head, period! I purchased this ball head because of the reviews and I am glad I did. I looked at the RRS and the Feisol units, but decided on this one. I also bought the Feisol VH-60 horizontal adapter kit, so it has to be stable enough to support my camera and macro lens at the end of the extension. I have not had any problems with it slipping. The only comment is that the friction knob adjustment has no fine tuning so its either loose or tight. Just make sure the ballhead is securely attached to the adapter head or it will inadvertently rotate loose. I also got the lever clamp model and would recommend that too. Would I purchase it again... Yes.

    Rated 5 out of 5 by from Very smooth and versatile Almost any tripod ball head can hold a camera up and reposition it. But a top notch ball head like the AcraTech GP can do that job with great ease, smoothness and versatility. It makes working your camera on the tripod a great pleasure. Move the camera to a new desired position, gently twist the lock knob and it doesn't move. Coming from a ball head that always moved a little after each adjustment and lock, this one was most wonderful, doing exactly what it was supposed to with elegance and ease. I love it!

    Rated 5 out of 5 by from I LOVE IT!!! I've used BH55 and BH40 and ball heads for years but wanted a lighter, smaller, stronger ball head that had consistent drag when not clamped down. I shoot Hasselblad H series bodies with Phase backs. Fuji glass like the 35-90 is very heavy and I was constantly having problems with the camera falling forward with lesser ball heads because there wasn't enough drag when not clamped down. The GP ball head addresses all my needs in this regard and is insanely light compared to the BH55. I've tried other bullheads like the arca-swiss p0 but they would slip under the weight of the glass. The GP ball head is the perfect balance of strength and ergonomics. The only thing they could improve on is the grip of the knobs which I find a bit challenging.

    Rated 5 out of 5 by from Solid and wonderfully constructed 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.

    Rated 5 out of 5 by from Great ball head 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.

    Rated 5 out of 5 by from State of the Art Rock-solid, beautifully crafted ball head with a bit of HR Giger to the design (think Alien). Having the locking lever clamp eliminates the possibility that I will inadvertently loosen a quick release plate or Arca-Swiss lens foot by turning the wrong knob when tired or distracted. It is very easy to dial in precise degrees of tension in order to track moving subjects without having the ball loosen up. The size is compact enough to use for travel. The gimbal notch makes it possible to shoot straight up for interior architectural shots. The largest combination that I have used with this head so far is a 5DMIII with the 100-400mm f/4.5-5.6 IS II, which the GP handled easily. Do wish the knob for turning the head laterally was larger and stuck out a bit more; on my Induro CT-414 tripod, the knob barely projects beyond the top plate so it is a little tricky to get a good grip on it.

    Rated 5 out of 5 by from Best Ball Head Ever I love this ball head because it just works flawlessly. The controls are very accessible, and when I loosen something, it loosens. I've used other ball heads that are just SO STIFF that there might as well not be a screw adjustment. Just leave it locked in. But not with this one. When it's locked in, it's solid. When you loosen it, it's free to move. And the tensioner is also great on the ball itself. It just works. It's expensive, but I won't need to buy another head for at least 10 years.

    Rated 5 out of 5 by from Small, Light, Functional 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.
