The Sunwayfoto DB-44DL Ball Head With Duo Lever Clamp is an extremely sturdy ball head with a greatly improved screw-knob and lever Arca-style clamp for compatibility with a wide variety of dovetail camera plates. The DLC-50 clamp has a screw knob on one side and a lever on the other; the knob adjusts the width of the clamp, and the lever locks it. It will accommodate any Arca-style plate in a range of 38mm to 41.5mm. The DB-44L features separate controls for pan lock, tilt lock, and friction. There are dual tilt grooves to accommodate switching to portrait orientation as well as full 90° front-to-back tilt without needing to alter the head's pan position.
Like other higher-end ball heads, the DB-44L features an ellipsoidal ball that helps it better handle off-center loads – this shape introduces progressive resistance to reduce accidents. But for smoother operation, the aspherical nature of the ball is subtler than that of other heads – the y-axis diameter is only 0.03mm longer than the x-axis diameter (other similar heads typically have a disparity of 0.07mm). The DB-44L supports loads up to 66 lb.
Rigorous testing has resulted in a very strong shell. The control knobs of the DB-44L are 100% metal – no plastic or rubber is used. This ensures a smooth operation as well as reliability and durability.
Well-marked components facilitate precise positioning. The tilt lock knob is laser-engraved with marks from 1 to 12, and the pan base features laser-engraved degree markers in increments of 5°. These, combined with the independence of the pan and tilt locks, make the DB-44L well-suited for capturing horizontally overlapping photos in order to create panoramas.
- The DLC-50 clamp features a screw knob on one side and a lever on the other. The knob side is for adjusting the width of the clamp, and the lever side is for locking the clamp. The opening range of 38mm to 41.5mm will accommodate any Arca-style plate.
- Situated inside the pan lock knob, the friction control knob allows you to handle safely a wide range of load sizes.
- Independent pan lock knob facilitates 360° panning movement with calibrated precision--ideal for capturing overlapping images when making horizontal panorama photos.
