Acratech 1155 overview

  • 1Description

The Acratech GP Ballhead is not only a first-class ballhead, it can also function as a gimbal head for shooting with telephoto lenses, and even be used upside down as a leveling base for stitched panoramic images. The GP Ballhead makes it possible for you to pan parallel to the horizon, even on very rough terrain, so there's no need for a separate leveling base for accurate panoramic images. All of this, and it only weighs 1 lb. It also includes a quick release clamp with bullseye level, double-speed knob and detent pin (which prevents the plate and anything attached to it from sliding out of the quick-release clamp when it's partially loosened).

Works as a gimbal head with lenses up to 400 f4.0
Weighs less than 1 lb (0.45 kg) with quick-release clamp
Easily holds over 25 lbs (11.4 kg) at any angle
Full movements allow any camera position
Precision machined aluminum
Compatible with Kirk, Arca, R.R.S., and many other QR plates
Fits all standard tripods (1/4-20 and 3/8-16 threads)
Laser-engraved dual degree markings
Beautiful satin black-anodized finish
Long-lasting stainless-steel hardware
All knobs are secured so they cannot vibrate loose and fall off
Oilless and greaseless ball will not attract or hold dirt and debris
Made in U.S.A.

    Acratech 1155 reviews

    GP Ballhead is rated 4.9 out of 5 by 74.
    Rated 5 out of 5 by from Smooth and strong I use this GP Ballhead with my Canon 5DMKII and my largest glass is a Canon 100-400mm telephoto. My tripod is a Manfrotto 190CXPRO4. This ballhead is SMOOTH! It is also plenty strong for my equipment. The rubber knobs are easy to operate, even for a hand that I cut off and it was reattached (years ago). No matter what size glass I use, the ballhead operates as though the equipment is weightless, and I love how quickly I can change the position of the camera to respond to subjects. It is also easy to put the camera in any position. It is a beautiful piece of equipment, made in the USA with great precision. I am very happy with this purchase.

    Rated 4 out of 5 by from Flexible and light I was torn between this and RRS BH-40 or BH-55. The 40 and the GP are about the same weight, but the GP does the neat head flip trick (see the video on Acratech). The GP also looks like it will be easier to maintain and I liked the simple operation on it. The clamp is surprisingly good, I have been thinking about putting a RRS lever clamp on, but there's one issue. Both companies have a system to keep the clamp from turning on the head screw, and yes they are different and incompatible. So if you want a RRS lever, get a RRS head. Overall, I'm pleased with the unit, solid construction with light weight and holds my 70-200 f2.8 without a problem. I also like the poor man's gimble head trick the head can do.

    Rated 5 out of 5 by from Versatile and capable ballhead. I use this ballhead with a Induro Carbon CT213 tripod and Canon 7D camera body and a variety of lenses, the heaviest being the Canon 70-200mm f/2.8L IS II lens. The controls are distinct enough that I can easily make adjustments by feel. I like the flexibility to use it upside down as a leveling base for panos -- easier than trying to get the tripod precisely level but needing an allen wrench to invert it is slightly inconvenient and it doesn't attach as firmly to the tripod when upside down. I've used it in gimble mode some but for most shooting I prefer to lock it down tight. It's lightweight for travel and super easy to clean if used in dirty/sandy conditions -- a huge plus! Have had it almost a year now and use it all the time. The folks at Acratech very responsive to support questions.

    Rated 5 out of 5 by from A Top Notch All in One Solution I have been searching for the right tripod head for years. I went through pan heads, standard ball heads, and nearly every other kind of tripod head you can imagine. I finally bit the bullet and purchased this tripod head along with 2 quick release plates. All I can say is WOW. The workmanship on this head is wonderful: solid and lightweight. The ballhead has a tension ring making the mounting of larger heavier lenses much safer and easier. Each knob has a soft rubberized grip that makes adjusting this head very easy even with gloves on. Movement of the ball is very smooth and having the ball itself exposed makes cleaning it and keeping it smooth very easy. The thing that really sets this head apart from many of the other ballheads I shopped for was the panorama head base. It can be used upright or upside down (see manufacturer's website for how to reverse the head) as a panorama head and includes a leveling base. There is also a gimbal head feature which makes handling a larger camera rig precisely very easy. The head takes standard arca-swiss style plates making it easy to find custom sized plates for nearly every camera setup. All in all, this head is everything I had been searching for and more. It easily handles my 1D Mk II + Canon 100-400 + 580 EX II combination smoothly and efficiently. I couldn't be happier with my purchase!

    Rated 5 out of 5 by from Excellent Product This is an excellent product, well worth the money. I had a different vendor ball head and found the camera twisted on the ball head mounting plate to camera interface in large wind with the camera at portrait position on top of the Golden Gate Bridge at nighttime. The acra-swiss plate (Kirk) use with the Arcatech GP Ballhead is great. Tee adjustments are super and you can use a large knob or a small knob to adjust. It's a gimball head as well and this makes it the last ball head I will ever have to purchase. I've used in in Australia and Singapore and it meets my needs with D7100 and 17-55mm f2.8 lens

    Rated 5 out of 5 by from Above my expectations - excellent I choosed this ballhead because it is light and allows flexible pan for landscapes (together with the optionals for panning)in invertered position. I must say I had some doubt about the construction, but it was a great surprise to find that the construction is excellent and, above all, there is a great engineering work behind this product. Moreover it's absolutely firm and confortable in every situation of use (at least in my experience with 5DII + 70/200). The only note is about the level spirit. It's not usable in ordinary position (I think it's the same on other ballheads), but if you use the ballhead in inverted position with the optionals for landscape everything is ok and you can level your camera quite easily.

    Rated 4 out of 5 by from Sturdy with great customer service I shoot mostly wildlife and plants and carry my tripod on trails where it is subjected to the elements. My previous ballhead got sticky and I was unable to clean it out. The open ballhead design of the Acratech allows you to blow out dust and sand grains. The design, especially the smooth-moving ballhead, allows lots of options for your shooting situation. When shooting extremely close up for detailed plant parts, I notice the ballhead slips a small amount after locking it down, so I have learned to compensate for that. A few months after purchasing the GP, my photography instructor noticed that there was no fluid in the level, oops, and he encouraged me to call Acratech to get it fixed. I called Acratech and then shipped the tripod head to them. They replaced the level for free, cleaned and lubricated the whole unit and returned it in less than a week. They were very helpful and I am encouraged to be working with such a responsive company.

    Rated 5 out of 5 by from The best on the market. I'm not sure why online reviews of ballheads do not include this piece. It's leaps and bounds ahead of the competition. Why did I purchase this? I will be honest, the price tag alone is enough to sober someone up. And I hesitated for quite some time, over a year. In the past I purchased a grip action Manfrotto ballhead and I liked it. I took it on a trip to Great Sand Dunes National Park and I instantly destroyed it. The sand got inside, stuck with the lubricant, and ate the entire system up. Smooth motion became a sandpaper-on-sandpaper choppy, grinding movement. And you can't open those enclosed ballheads and clean them in the field either; they are factory assembled and you need special equipment to put them back together. The Acratech GP design is amazing; No sticky lubricant to trap debris, easy to clean functionally, and still has the performance I need. Actually it has more performance than other ball heads because you're getting a leveling base for panoramic work AND a gimbal head for light weight telephoto lenses. I also hesitated to purchase because of the quick plate attach mechanism. It looked very loose compared to other systems I've used before; like manfrotto's locking lever system. I never worried about a falling camera. But honestly I like this system more; i'm fairly surprised. It doesn't lock per se; but the indent pin works well at preventing a slip in the event the plate attach mechanism comes loose. But it doesn't come loose. It's rock solid. It's a quick turn to release too. No fancy levers and locks to deal with. Place the camera in, turn, secure. Very quick to setup. The weight and compactness are also great features vs the competition. I often hike through the Adirondacks with my tripod slung over my shoulder and those are two things that matter; bulk and weight. It's extremely light weight; almost half a pound or great in difference from some other heads i've used. And the fact there's no large handles to catch branches is also nice. I could have opted for the smaller, lighter series of GP (GPs or GPss) but the difference wasn't enough to change my mind. When we're talking half a pound, yea that's great, a few oz's not a big deal. The GP appears more rugged and the knobs fit better with my hands than the smaller series. But I guess time will tell. Using this ballhead along with my new Manfrotto 190cx Pro4 I now have a tripod that weighs less than 5 lbs, that functions as a ballhead, gimbal and panoramic base, closes down to 24.85 and reaches 67.25, and does so much more for me. I cannot complain with this setup. Very happy. The only downside is that it does not include a baseplate. But that's fine because it gives you the ability to pick and choose which plate fits your needs; instead of indirectly paying for one that doesn't. Made in USA.
