The Sirui K-40X Ball Head is a versatile piece of equipment that every seasoned photographer should have.

The Sirui K-40X is an extremely robust fixture with pan control knobs. This manufacturer has provided Arca for the supplied quick release plate. The pan, tilt and quick release knobs are separate. The tension tool is integrated with the ball lock (tilt) handle. There is also a video pin on the board to keep the cameras from twisting. Other technical advantages of this device include:

  • Head tilts 90 ° for vertical orientation
  • Two bubble levels on this platform ensure the frame reaches the horizon in portrait or orientation
  • The manufacturer opted for an aluminum alloy

Our Take on the Sirui K-40X Ball Head:

Three control dials allow photographers to control very precisely the orientation of their camera. This device is compatible with medium format models and even some camcorders. With such a fixture, it will be easier for any photographer to adjust the panorama and tilt angle. This aggregate provides precise and measurable movement. There are degree markers on the body. For fans of panoramic photography, this is an indispensable functionality. The K-40X is CNC machined from aerospace aluminum alloy and anodized through an oxidation process for a durable, high-quality finish.

The internal ball lock of the K-40X head has a ball permissible variation of 0.01 mm. Such a fixture is equipped with a locking disc with orientation memory. This helps withstand the 77 pound load. The Arca-style platform is compatible with standard dimensions, so you can use compatible boards from other manufacturers with this quick release plate with a rubberized surface. The quick-release clasp has an additional release button. This arrangement prevents the camera/plate from being accidentally detached from the clamp. This increases the overall safety and stability of the head. The manufacturer made sure that the photographer and the videographer did not have any incidental situations.

Sirui’s hardware supports Arca style quick start with added security. Two bubble levels on this platform ensure the frame reaches the horizon in portrait orientation. This is very practical for every videographer. A friction control knob, integrated with the ball lock knob, allows any photographer to adjust the resistance to ball movement. You can buy this fixture today. Our store delivers any equipment in just 3-5 days. The manufacturer also used an aluminum alloy quick release plate with a rubberized surface. The screw is made of stainless steel. This means that this equipment will remain for centuries.
