Vibrations??

I recently mounted a Sigma 50-500 OS (Bigma) in my gimbal, locked in place. While on 400mm I lightly tapped the leg and saw the image really shake. I was using a Manfrotto 055CXPRO4 carbon fiber. I then mount the system up to an old heavy aluminum 3section Bogen and tapped the leg and got the same shake. I tried this with another al. 3-section Oben, same thing. Then I mounted the system on an Arca Swiss ball head and no shake! I have taken many photos using the gimbal head, some moving some still. So I guess I might be better off moving the camera or at least having my hands on it. I've experimented with leaving the OS on and off and saw very little difference. What do you think?

In fairness:
That your tripods would not withstand being whacked with no vibration occurring is an unreasonable expectation. If Manfrotto/Bogen were to make a tripod to withstand that test, you would need help carrying it to your photo-sight.
A more reasonable test would be to photograph a scene containing fine detail, at 1/2 sec. exposure with a remote release and view the result.
I, too, would like the tripod that will fold up to fit in my pocket, weigh in at .5 oz., and dispense ice and cold drinks with the push of a button. Wake me up for breakfast...

I agree. The long exposure would be a good test. I'm still amazed at the movement with just a very light tap. I've also noticed a light breeze will do about the same thing. Also a running car motor. I guess I need one of those old wooden, double leg tripods but weighs about 3lbs. I'm still looking.

Dare I suggest that a tripod is only as good as the connections between the camera and tripod?
I wonder how much play is present on the tripod mounts. I can see where a worn QR plate or slightly loose screw could cause problems. I have an old Davis & Sanford tripod that just won't tighten good enough for a long exposure.

I went to my doctor a few weeks ago. I said, "Hey, Doc, when I move my arm like this, it really hurts."
"Then don't move it like that," he told me. :D
I'm glad you were able to find a solution to your problem.

I haven't even mentioned mirror flop. When setting up for remote shooting (birds at feeder) maybe I can lock up the mirror if it isn't done electronically which may drain the battery.

Most cameras will let you use a setting to delay the shutter about one second after the mirror flips up.

I rarely use a remote or mirror up for my tripod shots. But I always either apply downward pressure on the camera or grab the hook from under the camera and pull downward. The hook is meant to add weight to help with vibration and I've seen experts add a sandbag to top of camera so No vibration happens at all. But who wants to carry more stuff to the field.

I agree. Another vibe source I've noticed is when you're wading a shallow stream with your tripod and set up for a shot, the water flowing past your tripod legs will cause shake.

I may not have the best tripod on the market but if I leave the strap on my camera and it is moving it will affect the photo. Take off any unnessary straps etc and weigh your tripod down with your bag or a sandbag if you're at home.....

You said you were shooting with the 50-500 lens. At full telephoto a heavy thought could shake the focus. I photo'd the full moon this morning on a concrete bridge. Trucks passing over shook the focus on my 150-500. Had to wait for the heavy loads to pass. Got real sharp pictures( soon to post)

Doing land survey work we would test to see that the compensators in our levels we would tap on the heavy wooden legs and watch the line in the level bounce up and down. If the shutter makes the camera shake that is one thing but tapping on the legs is not a fair test in my opinion.

I always carry two 25-lb sandbags in my trunk. When I go on a shoot, I carry the camera equipment, and my wife carries the sandbags. She tends to get annoyed when I don't bother to use them. :D

or, maybe she'd like to carry the camera and you carry the sand???
