Looking for a nice fluid head tripod, trying to keep it under 300.
Any advice for what would work well with a DSLR set up?
I will be running a 5D III with the Zacuto eye piece.
Are you for real man? Fur coat and no knickers! You spend serious cash on a camera and finder and want to put it on a crap or adapted photo tripod?
If you must get at least a Manfrotto 502 head, and 190 legs. I would go for a 438 leveller too.
But really you want a Sachtler ACE. It is worth the extra. You didn't mention lenses, would you put an EF 28-80 f3.5-5.6 mkIII non USM on your 5D3? If not, then why are you scrimping on a tripod?
If you want crap ramping then go for a cheap tripod. If you want time consuming frustrating balancing, go for a cheap tripod, if you want a tripod that will break, and for which spares are not available, get a cheap tripod.
It's like putting remoulds on a brand new ferrari. Or chip fat in a BMW 530d.
You want to shoot nice footage, need to get a nice tripod.
See that 300 (apples, pounds, oranges, pence?) either go and have a good night out with it, put it on a horse, or put it in the bank. You'll chuck your '300' tripod in three weeks and buy a Sachtler anyway.
Been that soldier.
