Hi
I am soon ( taking me a bit to commit the huge chunk of change) going to get a 500mm and up to now have mainly hand held shots and know very little about tripods/and monopods and the mounts and plates to go with. Can anyone give me some suggestions for a good set up does not have to be top of line but of course never want to have to worry about it collapsing. I am mainly going to be using it for bird and wildlife photgraphy.
I am sure this has been discussed some where in here but I could not find it. Thanks in advance for the help.
Go for Wimberly's sidekick. It's more than adequate for Canon's 500 f:4, and far more portable that the full size Wimberly head or its equivalents. I've owned the 500 f:4 for about 5 years, and initially I mounted it on Kirk's "King Cobra" head, which is a very smooth but heavy gimbal head that commits your tripod to using it only for long lenses. I tried out the sidekick, and now the King Cobra is gathering dust. It's extremely solid and beautifully machined, small enough to fit into the side pocket of your long lens pack, and copes with the 500 mm lens without difficulty if you have a solid ball head. It isn't enough to handle the 600 f:4, but the 500 mm lens only weighs 8.5 lbs. so it works just fine. And you can still use the same tripod for shorter lenses without having to replace the entire head.
I wouldn't want to use a monopod with this lens. It'll work well enough to support it for a few minutes if you're following, say, a football drive down the field. But the whole time you'll be worrying about dropping the thing. And trying to swap out a full CF card? Yikes. That's why those Sports Illustrated guys have assistants.
