Summary: I got the monopod to support the long lenses, including 500 nikkor. I was trying to decide between 4 and 6-section product. I am glad I decided to buy GT 5561 as the set up is fast enough, product solid and I clearly appreciate the advantage of the shorter length by over 5".
Summary: I use this with my Nikon 600mm lens for nature photography. It sets up quickly and is easy to use. Extremely sturdy, light as a feather. I really can not say there any down sides to this product except the price. But I'm a firm believer in, you get what you pay for. In this case I got a great product.
Pros: Durable, Good Value, High Quality, Very Lightwieght
Summary: Strictly speaking, I didn't need another monopod: they all do the same job, whatever the cost. But I'm very glad indeed that I bought this one. I use a monopod a lot - for supporting heavier lenses when out and about and for steadying the camera for close-ups and macro (where a monopod is often quicker and easier to use than a tripod). This Gitzo model is not just easy to carry, it's beautifully-engineered - and this enables quick and easy height adjustments.
Pros: Beautiful Movement, Durable, Great Features, Lightweight, Simple Controls
Summary: There are, quite simply, times and places when carrying a solid tripod is not possible, yet camera support is essential. This monpod delivers. It does what is needed, is fuss-free, easy to carry and does not get in your way. Built for the working photographer, I have tested it in some awkward places and got the steady shot I was seeking.
