I like these I like the first one more and the second one as they are compact. I travel by public transport, bike and foot I also like the third one as it is heavy for landscapes and I like the centre pole also open to advise on other tripods. But I do like compactness. My old tripod broke but it was only a cheap one (hama star 62) the leg snapped clean off.
It is to old a nikon d5100 but it will be upgraded to a d7100 but not for a long time It main use will be landscapes and long exposers
