I just shot a whole day with my Canon 7D on the monopod Ultra Stick L50 Velbon and a small ball that I bought for the occasion. I must admit that the monopod is very good and very convenient compared to the other: it is light, compact (it is within my backpack), unfolds very high (1 m 55) and remains very stable. The ball did not even served me so the monopod is handy with its rubber tip. Any small problem: everything is screwed. The camera is screwed and unscrewed (rather quickly that matter) on the monopod, like segments. So, to change the height of the foot, we must let go of the camera to keep the monopod when handling segments not the device is unscrewed too! But it is not so binding with respect to all its qualities. Anyway, I recommend, I am delighted with my purchase. In addition, I received ultra fast (2-3 days).
