Manfrotto l bracket q5 is a unique accessory that saves you time and increases stability. Q5 allows photographers to change camera orientation quickly from landscape to portrait without upsetting shooting position. Without an l bracket you would have to readjust setting of your current head each time you change orientation to exactly how it was, increasing setup time and decreasing stability. Magnesium structure provides a sturdy solution in terms of stability and transportability for all types of equipment. This light accessory helps to extend vertical and horizontal range of movement, keeping camera's weight centered over tripod and avoiding lens movement when flipping from landscape to portrait position. L bracket is adaptable to different camera models maintaining a high level of precision and ergonomics. At bottom of l bracket are two 501pl qr plates which slide onto your rc5 head and provide a perfect weight balance for heavy equipment.
