I do lots of landscape and macro photography as well as bird photograph with 100-400 IS lens. I use the Gitzo tripod with Linhof head and Novoflex MiniConnect plate. I am frustrated with this setup which I have been using for many years. I would like to find a plate and head that would hold my 100mm lens firmly while doing macro. I also don't like the knob for tightening the head. Any suggestions?
