Arca-Swiss Z1 sp overview

  • 1Description

The Arca Swiss Monoball Z1 sp (Single Pan) Ballhead builds on the success and popularity of their B-series ballheads. Z-Series ballheads are just as elegant, and even more perfect. The size and weight of the ball heads have been significantly reduced. The ball and fastening are now assembled using a patented bayonet mount. Various accessories can thus be quickly mounted to adapt the tripod as required.

In addition to the proven, patented Arca-Swiss features, including aspherical ball heads, axial clamping and PMF (progressive motion related friction control), the Z-Series also boasts new technical developments and optimized materials and coatings. The Z series can withstand an incredible 130 lb (59 kg) off-axis.

This model is the "sp" version, which features a single panning base. The Z1 head is also available as the "dp" version, with a double panning design.

Ever since their introduction over forty years ago, the Arca Swiss Monoballs have been at the forefront of quality and performance. Today, their unique shape (an ellipse rather than a sphere) is still what separates them from all others. With other ballheads, no matter how good the tension modulation, you invariably will need to increase the tension control as you move the load away from the center. This is because gravity has a greater effect on gear when not perfectly level.

The Arca Swiss Monoball eliminates the need to modulate the tension, because its elliptical nature corrects it by virtue of its own design. The load stays exactly where you tell it to once it's locked into position. A separate control is set to apply a constant minimum friction, which allows the photographer the peace of mind that comes with knowing that his gear will never move of its own volition. The heavier the equipment, the more the advantages of the Arca Swiss become evident.
A tension adjustment thumb-dial is built into the indexed friction control knob.
Includes a round camera mounting base, with a 3/8" screw.
Base diameter of 2.7" (69mm), excluding knobs

    Arca-Swiss Z1 sp reviews

    Monoball Z1 sp with 3/8" Screw is rated 4.6 out of 5 by 20.
    Rated 2 out of 5 by from Check your threads Arca Swiss is known for its quality in performance and finish of their ballheads. Well I am beginning to question that. I bought one monoball Z1 from B&H and two from B&H's competitors:Z1 sp & Z1 dp and was suprised when I turned over the ballheads to check out the threads before attaching them to my Gitzo GT3530LS tripod. All three ballheads had threads that looked like they were chewed up. They weren't smooth, had chucks of threads missing or had holes in the threads. Three ballheads!! Shame on your quallity control Arca Swiss. There all going back. I ordered a fourth one. Hope this one is better or I'm giving up on Arca Swiss.

    Rated 5 out of 5 by from Excellent ballhead I used this ballhead on a Gitzo 1341L tripod in all kinds of weather. Never an issue with operation. I have owned Kirk, RRS ballheads in the past. The kirk was heavier. On the RRS, the panning knob and lock knobs require you to switch hands on the camera which lead to too much fumbling around. This is perfect. Solid panning lock, unlike my small Markin's. The ovalized ball works as stated, and this is smaller and lighter than the older B1. Overall an excellent ballhead. With a RRS lever clamp this is an incredible combination. No weaknesses at this point

    Rated 5 out of 5 by from Top of the line ball head! I have used a Markins head and the very interesting Novoflex Magic Ball made for the Berlebach tripod but nothing compares with the Z1 for large format use. I wish I'd gotten this about six years earlier. It is smoooth and precise. The asymmetrical ball is hard to believe until you try it. I can only sing praise of this ball head ...What a combination - Arca Swiss and B&H.

    Rated 5 out of 5 by from Awesome head Great ballhead that does everything you want. Mounts perfectly on my Gitzo 3541LS tripod. I ordered this version because I replaced the screw mount with a RRS B2 AS II quick release plate. It fit perfectly and does not hit anywhere. To remove the installed screw plate you just need a #11 socket. Motion is smooth and locking with a quick twist is solid. There is no movement at all during the locking, a problem I've had with cheaper heads. It is nice to know I'll have this one for life as it will hold anything I could ever want to mount on it.

    Rated 5 out of 5 by from Great ball. Solid, very solid and not heavy. Smooth and comfortable operation. Checked with Tamron 180 + 1.4 TC on a Gitzo 2220 tripod and performs very well. Manfrotto 323 QUICK CHANGE RECT.PLATE ADAPT. used to fix the lens. Camera was a Canon EOS 30D. Little blur appears at speeds about 1/30 - 1/15 because of tripod vibration, I guess. At lower speeds, 0.5 seconds blur disappears again. No mirror lock up during tests. All test with camera/lens tilted about 45 degrees as this position is more critical than horizontal.

    Rated 5 out of 5 by from The Last Ballhead You'll Ever Need. I've got the Z1 with a QR clamp (for an L-Plate) from RRS mounted on some Gitzo GT3541 legs and could not be happier. It's a pricey setup, but I'm more than confident that this will last for a very, very long time. I shoot my stills with a Nikon D600 (with grip) with either a 14-24mm, 24-70mm or 70-200mm and, for once, not at all worried about my camera dropping or creeping as I was with my previous tripod setups. This thing locks tight and pans smoothly. I bought it for an upcoming trip to Europe and cannot wait to see what I can get. If you're thinking about purchasing this ballhead, I'd highly recommend picking up a separate QR clamp to receive the full benefit of shooting on a tripod.

    Rated 5 out of 5 by from Asymmetrical ball for the win. If you're looking at this ball head, no doubt you're already aware of its competitors, of which there aren't that many at this price level. Most of them are very, very good, and it essentially boils down to personal preference; you really can't make a wrong choice at this level. But what makes the Arca-Swiss Z1 stand just a hair above the others, in my opinion, is its asymmetrical ball design. It's a simple design concept that allows gradually increased tension as you move the camera past 45 degrees off-axis. This does two things: a) it prevents your expensive gear from flopping over and banging into a tripod leg, and b) it actually allows for a constant force needed to move the camera since it proportionally counteracts the effect of gravity as the camera goes more off-axis. Ingenious! The fact that this is one of the smoothest, lightest pro balls out there is just icing on a very nice cake. Some have noted that the panning lock can be difficult with wider tripod platforms. It's a teardrop design, the tail of which is completely above the base from full loosen to full tighten, so I haven't encountered any problems at all. I use the Kirk SQRC-Arca specialty quick release clamp, which is custom designed to fit this head. The hex bolt securing the camera platform on the Z1 was a locked in tight and required a ratchet and a bit of power to unscrew, but I got it loose and Loctited the Kirk in its place. Works great!

    Rated 4 out of 5 by from The ballhead moves smoothly. I use the Arca Swiss Monoball Z1 sp with GITZO 2330 tripod. This ballhead is very good. Moved smoothly and locked tightlyalthough the lock knob is smooth and light. There is only one weakness. Round plate contacting with a bottom of camera is slippery.
