Does it has the function to prevent from hand shaking caused from a long exposure?

Yes. The Canon 18-200mm has optical image stabilization. This function can be turned on or off as the user desires. However, optical image stabilization will only help for 3 or 4 stops. For really long exposures, the use of a tripod is recommended. I hope this helps.

Worth every penny. No matter if you manually focus or zoom. Set your camera to how you want the shot to look first. This device is to prevent shaking or blur while moving. Every time I use it I get the shot I need. I hope this helped.

I think so especially if you tend to be clumsy, bad sense of balance etc. When I try to stop I tend to get tipsy so I'm thinking the stabilizer bar would have helped. Also when I'm jumping it would have kept me more upright and balanced (if that makes sense).

Yes it does. I personally have taken 40+ second exposures. And yes you can have intervals and/or delays set with that as well.

Yes you can set it at 2 or 10 seconds. There is also about a one second delay when recording video. This may just be the camera or a built in self timer to not record your hands.

I have found it to be very effective in controlling perspiration on my hands. I've been using it for several years now.

this won't change the functionality of your camera. almost any canon camera now (which this is for) can do long exposures

To keep it reliable it does not hurt to shake monthly to avoid separation/settling, similar to a fire extinguisher. Do not need to shake before use like you do spray paint.

I haven't focused on my hands but the skin on your hands is as fragile as your face so i would believe it would help. The issue would be the harsh substance your hands come in contact.

You can move your hand. Depending on how tight you make the grip it may restrict access to some of the minor controls.

No, it doesn't go up high enough to keep you from clenching. It will keep you from curling your wrist.

It helps. Not 100% for me. I am highly sensitive and wear an EMF pendent too and still feel some low level that irritates me after prolonged use.

Jeffrey,I use this to minimize camera vibrations when the shutter button is pressed. I'm an astrophotographer and when the camera is mounted on my telescope for a picture, it will giggle the scope when I either click it or when I keep the shutter open for 5 minutes or so, if I have to keep my finger on the button. With the remote shutter cord there is no vibration and the photo comes out clear and sharp. The old film cameras had the same thing for decades and decades. They called the item a "cable release" back then. I've been shooting pictures through the telescope for 40 years.

I believe I would ask the manufacturer who makes this product that question! I never experienced the shakes nor rapid heartbeat, it just didn't work for me!

I do not know the answer to that as I (thankfully) have not used it. I tested it by pushing the button and it works. I'm thinking that you would not need a prolonged time. Anyone (person or animal) would back off pretty quick.

Yes, that is its function. It also measures your pulse (heart beats per minute).

It only communicates with one of the Pentax cameras it was designed for, such as the K-r and the K-5. It does not work with external devices. The shake reduction is in the camera and is controlled by moving the focal plane. The astrotracer function in the GPS moves the focal plane in the camera at the same rate as the earth's rotation depending on your latitude. This is the reason that the length of time it works (exposure) is dependent on the focal length of the lens you're using; it can only move the focal plane so far until it has to stop.
