The Dolica B204 Professional Dual Knob Ball Head is an upgraded classic design ball head that utilizes a dual knob design to independently lock pan and tilt separately. The advantage of independent locking knobs is they are able to isolate tilt angle and pan across the same tilt angle. This is a great feature for horizontal panorama shots as well as shots that require the same tilt angle.
This heavy duty ball head can carry a camera load of up to 17 lb and makes it suitable for entry, mid and pro level DSLRs. It has upgraded features such as degree angle marks and anti-slip quick release lock. The Dolica B204 comes with a quick release plate with rubber padding and a 1/4 thumb screw to ensure a tight fit with camera.
