most of the time you will find a tripod able to hold 4kg with a 3way pan and tilt head works great. generally brands arent so important when dealing with such light loads. most brands use a 1/4" thread so most heads are interchangeable inbetween brands. i currently have a velbon sherpa 200r and qb-157 head. great combo for most photography. i also use a macro slider with it. it supports a 5d and 180mm lens so a fair bit of weight. quick release is great particularly with multiple lenses i can switch a lens in 30secs and its more safe. also find the best point of balance with your setup. sometimes youll have the body attached sometimes the lens.
