You're on steady ground®

Thank you for choosing Oben!

This versatile and durable Oben tripod and ballhead is a compact and lightweight kit that sets up quickly, folds up neatly into its own carry bag, and offers a variety of options ideal for the photographer on the go.

The Oben AT/CT-3500 Series 5-section tripod features twist locks for fast and effortless height adjustment. Each leg can be positioned independently at three locking angles to ensure stable support when shooting on uneven terrain. Integrated spiked feet beneath the nonslip rubber feet provide stability on soft ground, grass, or sand. The adjustable center column is equipped with a spring-loaded weight hook for added steadiness in windy conditions.

This tripod boasts several options for low-angle shooting. A low-angle center column is included with the tripod for mounting a camera close to the ground. The tripod's standard center column is also reversible for extremely close proximity to the surface. For additional adaptability, one leg of the tripod can be removed and used as a completely functional monopod.

Oben's BE-Series dual-action or BZ-Series triple-action ballhead is included with the tripod to provide smooth and effortless operation. It features two locks that provide independent adjustment of the ball and panoramic base. Integrated bubble levels ensure accurate camera alignment with the horizon. An Arca-type quick-release plate allows for mounting and dismounting the camera quickly and effortlessly.

Please read through this entire manual before using the AT/CT-3500 Series tripod and the BE/BZ-Series ballhead.

Ballhead Operation

The AT/CT-3500 Series tripod and BE/BZ Series ballhead come assembled. During normal operation, the ballhead will occasionally have to be removed in order to make adjustments to the tripod.

THE TRIPOD MOUNTING SCREW

The tripod includes a mounting screw with a 3/8-16 thread on one end and a 1/4-20 thread on the other, allowing you to mount a tripod head with either size mounting socket.

To switch between the two mounting screw sizes, do the following:

1. Unscrew the ballhead, and use the included hex key to loosen the set screw that is next to the mounting screw.

2. Unscrew the baseplate from the tripod.

3. Lift the screw out, reverse it, and insert the opposite end back into the baseplate.

4. Replace the baseplate by screwing it back into the tripod and tightening the set screw with the hex key.

MOUNTING THE BALLHEAD

When returning the ballhead to the tripod, follow these steps:

1. Tighten all of the knobs on the head.
2. Align the ballhead socket with the tripod mounting screw.
3. Rotate the ballhead clockwise onto the tripod, and tighten it by hand. To prevent damage to the ballhead and mounting screw, do not overtighten.

Note: If a different size mounting screw is needed to mount the ballhead, refer to The Tripod Mounting Screw section above for instructions.

MOUNTING THE QUICK-RELEASE PLATE TO THE CAMERA

The quick-release plate has a 1/4-20 screw that fits most cameras.

1. Loosen the quick-release knob by turning it counterclockwise, and remove the quick-release plate from the ballhead.

2. Align the mounting screw with the threaded socket on the base of the camera.

3. Use the supplied hex key, a slotted screwdriver, or the D-ring to tighten the screw into the camera's socket.

Ballhead Operation (continued)

Note: If a 3/8-inch mounting screw is needed, use the included 1/4 to 3/8 adapter bushing.

Warning: Some manufacturers' plates do not meet our specifications and may not lock your equipment securely in the Oben quick-release clamp. Please test all camera and lens plates made by manufacturers other than Oben to ensure compatibility.

MOUNTING THE CAMERA AND QUICK-RELEASE PLATE TO THE BALLHEAD

After mounting the quick-release plate to your camera, make sure that all knobs on the ballhead are tightened, except for the quick-release knob.

1. Turn the quick-release knob counterclockwise until it stops.

2. Mount the camera to the ballhead by placing one edge of the quick-release plate into the ballhead. Then lower the other side until the quick-release plate is lying flat in the quick-release clamp.

Note: Make sure the mounting screw's D-ring is flush with the bottom of the plate.

1. Turn the quick-release knob clockwise to lock the plate.

The main locking knob locks and unlocks the ballhead, which allows for changing the position of the camera.

When changing camera positions via the main locking knob, always keep one hand on the camera.

Turn the knob counterclockwise to unlock the head, and clockwise to lock it. Make sure that the knob is firmly tightened before letting go of the camera.

Use the 90° groove to switch between landscape and portrait orientations.

Ballhead Operation (continued)

TENSION KNOB

(BZ-217T & BZ-226T BALLHEADS)

The tension knob is used to control the amount of friction on the ball in order to maintain strict control when positioning it. The tension knob is the medium-sized knob, and it has a different look and texture than the main and panning locking knobs so you won't confuse the two, even if you're operating them by touch.

ADJUSTING THE FRICTION (BZ-217T & BZ-226T BALLHEADS)

To adjust the friction accurately, follow these steps:

Diagram of a mechanical device with rotating components and red arrows indicating motion (no text or symbols)

1. Turn the locking knob and the tension knob clockwise until they are completely tightened. Then mount the camera and lens combination that you will regularly use.

2. Once the camera is securely mounted, hold the camera with one hand and completely loosen the locking knob by turning it counterclockwise until it stops. Then gradually loosen the tension knob until you reach the desired friction level.

3. Tighten the locking knob to secure the camera in place, or when you aren't holding onto the camera.

Ballhead Operation (continued)

PANORAMIC BASE

The base of the ballhead can be independently rotated 360°. The base is controlled by loosening the pan knob.

1. Twist the knob counterclockwise to unlock the base.
2. Rotate the base to the desired position, and then lock the base by turning the knob clockwise.

COUNTERWEIGHT

When shooting in windy conditions or when using a telephoto lens, the stability of your camera is critical. A built-in spring-loaded hook at the bottom of the center column allows you to hang a counterweight, such as a sandbag (not included) or loaded equipment bag (not included), to provide increased stability.

Tripod Operation (continued)

SPIKED FEET

The rubber non-skid feet are for use indoors or on flat surfaces. Spikes are for soft ground, grass, sand, and uneven terrain.

To expose the spikes, follow these steps:

AT/CT-3535:

Remove the rubber feet by pulling them off. When finished using the spikes, replace the rubber feet.
