Hi if i'am posting in the wrong place i am sorry,
My question is i have a canon 10d plus a selection of lens just recently i have become the owner of a 600 f4 which as you all are aware is big and heavy,i have taken some really good bird shots with it on a bean bag from a hide,my big problem is mounting it for ease of use.
can anyone recommend a suitable tripod/ head setup which gives a secure mount to the lens, i want to be able to carry the setup on my shoulder without any chance of it coming apart,i want a lightish but solid setup ,what is the general opinion on carbon fibre pods?are they as solid ,i know this is a never ending story but the more input i recieve will give me a much wider knowledge on the subject thanks paul
I have a Fiesol CF tripod and monopod. I am quite happy with both, especially considering the price. I use the monopod with a Sigma 120-300 2.8 zoom and a 1.4TC. I have shot 420mm at 1/15 second with fairly good results. I also use a Acratec ballhead and a Wimberely Sidekick.
I also have a 600mm. I use a Gitzo 1410 with a RRS ballhead and a Wimberely Sidekick. No question about it the Gitzo and the RRS ballhead are better. Part of this is due to the weight (over 4 kilos), while the CF and the Acratec come in at less than 2 kilos.
Now comes the physics 101. Motion is a direct function of force and an inverse function of weight. The force in this problem can be considered constant (you dont press the shutter with more force depending on the tripod you use). But the heavier the tripod and ballhead (and gimbaled mount) is the less they will move if force is held constant. This is good when you are taking pix, but bad when you are carrying.
To some extent this explains why there is such a debate. You are always trading off the ease of carrying your support system against the quality of the image from that system. And not everyone has the same scale for rating ease of carrying or quality of image.
In addation the location of the weight is important. It is much easier to tip over a light CF tripod with a heavy RRS ballhead at the top than to tip over a heavy 1410 with a light Acratech ballhead at the top.
As for your support system comming apart, this is more a function of the ballhead than any other part. The Acratec ballhead is rated to 25lbs, and the RRS 80lbs. I have never had any slipage with them. But dont forget I am using a gimbal type mount. The implication of this is that the weight is well ballanced. Thru experience I can place the plate in the mount by eye and the ballance is nearly perfect. This places much less stress on the possible failure points.
If you go to the RRS web site you will notice there are several different plates for different big lens. And the same is true for the Wimberely site. While these plates are not cheap they do provide better ballance. And I will point out that the plates they recomend may not be the best one for you to use. I had to return the first one I got for a different size.
The upside is once you get the setup tuned up the way it is suppose to be it is a joy to use.
