Question about OIS
 
We have an xl1 at our church that we keep the ois on. The people who run it are not professional camera operators and with out it the pic is very shakey.

I have noticed that when we do a pan that when the camera stops, the picture is still moving and it never ends up where you originally expected it. Is this normal or is something wrong with the lens? Would a new lens help?

We usually run it on the auto setting. It does not do this when the ois is off, but the pic is shakey as mentioned earlier

Any help is appreciated!!

That's why most people turn of the OIS while running on the sticks. When you pan the camera, it confuses your starting and stopping of the pan as camera shake and tries to counteract it.

Best to turn it off while on the tripod. There are a few tricks to getting smoother pans such as grabbing the panhandle close to the head, or putting a rubber band (like a #64) on the panhandle and pulling it with your finger. This helps absorb the sudden acceleration/deceleration problems.

So in short, what you are experiencing is completely normal.

Gregg is absolutly right with OIS "on" every move you make with the camera is concidered as a shake or unwanted movement by the OIS system. So, when you stop the movement it will kind of back up slightly, in compensation.

When on a tripod keep it off. When hand-held it is invaluable, and the best I have seen.

Remember, its whole purpose is to stop or compensate for movement!

Some thoughts on reducting cameas shake without knowing the details of your setup.

Sounds like the tripod you are using may not be very steady. A better tripod with a good fluid head should help the operators do a better jobs.

Be sure the camcorder and tripod are on a steady and stable floor, not on a bench or pew where people standing and sitting can cause movement.

You may be able to improve things a bit if you can move the camcorder closer and use less zoom-in.

If you use an external monitor the operators will not need to have their eye to the viewfinder and that can eliminate a source of shake.

A change in camera poition/angle may reduce the need for camera movement such as pans.

A remote zoom controller such as the Canon ZR-1000, or the third-party alternatives will reduce the need to trouch the camcorder body for changes in zoom setting.

Great Responses
 
Thanks for the great responses....We will try the Canon ZR-1000 to see if that works. I think the biggest problem is actually touching the camcorder to do zooms and focus...Hopefully this will take care of it.


THanks again!!
