Acratech GP-S overview

  • 1Description

The Acratech GP-s Ball Head has the ability to function as a gimbal head and as a panoramic head, providing you with incredible positioning flexibility and stability for your equipment. Gimbal heads are desirable when shooting with telephoto lenses, especially when following moving objects.

The GP-s Ball Head is designed with a small diameter base diameter of 2.1" to allow it to be used with travel type tripods where the legs fold around the tripod head. The smaller base diameter allows the tripod legs to fold more compactly.

Even when using your tripod on rocky, uneven terrain the GP-s Ball Head allows you to pan parallel to the horizon, eliminating the need to carry a separate leveling base to create accurate panoramic images.

Fits all standard tripods (1/4"-20 and 3/8"-16 threads).
Easily holds over 25 lb (11.4kg) at any angle.
Works as a gimbal head with lenses up to 400 f/4.0
Weighs 0.91 lb/0.4kg with quick release clamp.
Reduced base diameter of 2.1" (53mm).
Dual laser engraved calibrated panning scales.
Full movements allow any camera position.
Precision C.N.C. machined.
Compatible with Kirk, Arca, R.R.S., and many other quick release plates.
Beautiful satin black anodized finish.
Long lasting stainless steel hardware.
All knobs are secured so they cannot vibrate loose and fall off.
Built-in safety detent pin and double-speed thread.
Separate tension and pan lock controls with rubber knobs.
Oil-free and greaseless ball will not attract or hold dirt and debris.
Made in the U.S.A.

    Acratech GP-S reviews

    GP-s Ball Head is rated 4.7 out of 5 by 32.
    Rated 5 out of 5 by from Great Ballhead Excellent control over camera position in normal and leveling base configuration and in gimbal config, although, it isn't as good as a real wimberly head. Locking the camera is secure and there is no movement unless your tripod isn't stiff enough. The pretension system is pretty nice as is the fact that the nobs are not just bolts or nuts, but captured nobs that can't be removed by accident. Cons... It isn't exactly light or small. This is a full sized heavy duty ball head, not a lightweight compact travel head. When used as a leveling base, it is VERY EASY to accidentally release the quick release head instead of the pan nob. It requires caution.

    Rated 5 out of 5 by from Exactly what Acratech says it is. This gimbal/ballhead does everything Acratech says it will. The ballhead and gimbal head functions very well. It holds my 70-200mm f2.8 with ease in any position. I use it with a manfrotto tripod and the gimball head does not throw off the balance in the least. The action is very smooth and the tension is easily set to desire. The only con: Acratech states not to carry the camera attached to the ballhead on the tripod. They are right, the camera will come down and remind you with a nice bump if you put the tripod over your shoulder with the camera attached. Acratech warned me but now I'll remember.

    Rated 5 out of 5 by from 30-year professional give GP-S 4.5 stars I've been a shooter since I was 18. I have had so many bad relationships with ball heads; I was determined not to do this over again! After about three days of research by filtering qualified reviews, the Acratech GP ballhead was in the queue to do a hands on. Wow! I am amazed at how immovable it is with my D4/RRS L-bracket mounted. And it's lightweight! Excellent engineering and doesn't make my carbon fibre tripod bizarrely top-heavy. Controls are simple, effective and a well-thought out size. I dock it by half a point because the rubber slips a little when I tighten the knobs. Highly recommended - try it out if everything else has frustrated you!

    Rated 5 out of 5 by from Excellent! Excellent multi-functional head. The extra compact size is appreciated. I take lots of long exposure landscape shots so an absolutely steady head is essential and this head hasn't let me down! Being able to flip the head around to use the leveling base on top for panoramics is an awesome idea. The only con with this is when doing so, the base doesn't lock in on the top of the ball head mesh with the teeth like it does when attached to the bottom of the head since there aren't any teeth at the top of the head base. So essentially its held in place by friction, but nonetheless its works great!

    Rated 4 out of 5 by from Nice quality ball head I like the open structure. It should never need to go back to the factory. It's well made and it's been stable and convenient to use.One thing to consider, and I will send this recommendation to Acratech, is that the leveling plates they sell are the wrong size base for the GP-S model as their base is a bit wider. If you bought the GP-S to sit atop a smaller tripod like the Gitzo 1542T I have, the larger leveling base won't fit well. I've also used this head on a Gitzo 3530 and it worked well there, too.Dinged one star due to the high price. I could have bought a nice new iPad. Or a new lens. Both are higher-precision instruments with more expensive parts and engineering than this ball head.

    Rated 5 out of 5 by from wow! So lightweight. I've been using RRS ballheads which are very good but HEAVY and they can bind if exposed to too much dust. Also, for my Traveler tripod, the RRS traveler-size ballhead was still pretty large and heavy. Not this guy. Very well made and so light! Holds my D3X and a 24-70 / f2.8 with ease. Excellent controls. Smaller than the RRS - still can't completely fold the tripod to its minimum traveling size but you can get pretty close. Plus no more worrying about the weight and adverse (dusty) conditions. Another big plus, the mounting plate is tiny yet works very well. And you can keep the L-bracket detached until you need it unlike other L-brackets for the D3X that really get in the way. Finally, the detent pin is a really nice touch making sure your camera doesn't go boom. Excellent buy.

    Rated 4 out of 5 by from Form and Function Finally had a chance to use this fine crafted tool in the field. Having a limited tripod (with only a single level/stage leg set), this has greatly improved its usability and convenience. It seems to be very well thought out having more design features integrated into a single product i.e.: open ball design for easy maintainability, light gimbal option, leveled panning base (when inverted)and big knobby controls for days when use of gloves are a must. Only 4 stars because I believe that everything can still be improved like a spirit level for vertical orientations but otherwise it's an awesome product. You actually get more features versus others which are almost in the same price range. Plus it's one of those things that you get once and be done with it. I've also considered other designs which were more streamlined and aesthetically better looking but form does follow function and this one is growing on me.

    Rated 4 out of 5 by from Very convenient for travel I almost always use the gimbal approach, but the ball head is nice for some shots. The size and weight make it ideal for travel. I recently used it in Ladakh, to shoot blue sheep and snow leopard. I was using a 500mm f/4 lens, which is really too big for this head, but it performed very well. I couldn't have gotten away with a big bull head, as I had to carry the camera, lens, teleconverter, and tripod on my back everywhere at almost 4000m altitude.
