Acratech GP-S and GP-SS Ballheads

Acratech GP-SS ballhead

The Acratech GP / GP-s / GP-ss ballheads are elegantly designed ballheads with a satin anodized finish. Acratech products are available direct, or at B&H Photo.

All of the GP ballheads are the perfect complement to a lightweight tripod, with the GP-ss ideal for cameras like the Fuji X100 or Fuji X-Pro1 or Sony NEX-7 or Leica M9. And all of them are perfectly capable of supporting larger camera, but I’d suggest the GP model with its larger clamp for pro-size DSLRs.

I was impressed with the attention to detail with the GP/GP-s / GP-ss ballheads: the fit and finish, the stainless-steel and brass parts, the built-in spirit level., the laser-engraved markings. It’s clear that a great deal of thought went into the features of these heads, right down to the removal of excess metal from the cross member.

After speaking with Scott Dordick at Acratech, I came away realizing that Acratech is one of those companies with a deep comittment to design excellence. That’s the type of company I like to support when I buy my gear. And Made in the USA is a plus too.

GP Models

I tested these combinations:

  • GP-SS #1180 (smaller ballhead with knob clamp)
  • GP #1155 (Regular size ballhead with knob clamp)
  • GP #1157 (Regular size ballhead with lever clamp)

The GP and GP-s models are slightly different. According to Acratech:

The GP-s has a smaller base diameter and a relocated pan knob so it provides additional clearance for compact, travel tripods where the tripod legs fold over the tripod head”.

I saw no particular need for the GP-s model even with my tiny Gitzo 0531 tripod; I used the GP and GP-ss models. When I use a small tripod setup, I stuff the tripod with head into a side pocket of my North Face Recon day pack.

Which clamp?

With the knob clamp, the spirit level remains exposed and visible when the camera is mounted. I also like the fact that it keeps the clamp form-factor smaller, a factor for stowage in the side pocket of my pack.

With the lever clamp, the spirit level is covered once the camera is inserted; see the two photos on this page and why this is so will be immediately clear.

Weight as actually weighed on my lab scale.

GP-SS: 386g with screw clamp
GP-S: 400g (nominal)
GP: 452 with screw clamp
GP: 475 with quick release lever clamp

Together with a small and light tripod like the Gitzo 0531 tripod, carrying a tripod need not be so burdensome.

The 386g weight is in line with the Really Right Stuff BH-30, but I prefer the Acratech head for its superior control layout, which interferes less with rotating/aiming the camera.

Reader comments

I've been following your blog and subscribing to Making Sharp Images and DAP for a few years now. I got into photography after buying a Canon Digital Rebel in 2005 so consider myself a relative newcomer. Despite not having the time I'd like to invest in improving my craft, I really enjoy your articles. I learn something new every time I read them. I appreciate the attention to detail. I especially appreciate the MSI articles about avoiding blur. They are worth repeated study.

I am glad to see you review the Acratech ballheads. I think that they don't get the attention they deserve. Maybe people are freaked out by their very unconventional design.

I have used the Acratech GP ballhead with my Canon 40d and 7d and a variety of smaller lenses and also with a Wimberley Sidekick for my Canon 500 and 100-400 for about 18 months now. It's lightweight, well built, and gets the job done. I have used it everywhere from my own backyard to the Serengeti and it has never let me down. Acratech doesn't quote inflated weight limits - they say that they can handle 25 pounds at any angle and that's what they do with little fuss or hassle. Their design makes cleaning a non-issue. They don't need lubrication or much maintenance at all to keep working.

I also use their separate leveling base which works great as well. Note that the ballhead can be flipped over and used like it has a leveling base for quick panoramas in a pinch but it's a bit awkward so I recommend a dedicated leveling base. I agree with another comment that notes the limitations of the gimbal mode - I would only use it in a pinch if I forgot my Sidekick. With a replacement lens foot for my 500/4 the weight is well centered over my tripod and I have lost little if any functionality over a full Wimberley. When you are limited to 15 kg of luggage on an African Safari and wish to actually have a few changes of clothes as well you will really appreciate the Acratech GP ballhead.

There are many quality options out there from manufacturers like RRS and Arca-Swiss but I recommend everybody at least take a hard look at the Acratech options.
